Patch series "ima: carry the measurement list across kexec", v8.
The TPM PCRs are only reset on a hard reboot. In order to validate a
TPM's quote after a soft reboot (eg. kexec -e), the IMA measurement
list of the running kernel must be saved and then restored on the
subsequent boot, possibly of a different architecture.
The existing securityfs binary_runtime_measurements file conveniently
provides a serialized format of the IMA measurement list. This patch
set serializes the measurement list in this format and restores it.
Up to now, the binary_runtime_measurements was defined as architecture
native format. The assumption being that userspace could and would
handle any architecture conversions. With the ability of carrying the
measurement list across kexec, possibly from one architecture to a
different one, the per boot architecture information is lost and with it
the ability of recalculating the template digest hash. To resolve this
problem, without breaking the existing ABI, this patch set introduces
the boot command line option "ima_canonical_fmt", which is arbitrarily
defined as little endian.
The need for this boot command line option will be limited to the
existing version 1 format of the binary_runtime_measurements.
Subsequent formats will be defined as canonical format (eg. TPM 2.0
support for larger digests).
A simplified method of Thiago Bauermann's "kexec buffer handover" patch
series for carrying the IMA measurement list across kexec is included in
this patch set. The simplified method requires all file measurements be
taken prior to executing the kexec load, as subsequent measurements will
not be carried across the kexec and restored.
This patch (of 10):
The IMA kexec buffer allows the currently running kernel to pass the
measurement list via a kexec segment to the kernel that will be kexec'd.
The second kernel can check whether the previous kernel sent the buffer
and retrieve it.
This is the architecture-specific part which enables IMA to receive the
measurement list passed by the previous kernel. It will be used in the
next patch.
The change in machine_kexec_64.c is to factor out the logic of removing
an FDT memory reservation so that it can be used by remove_ima_buffer.

We use sync_core() in the alternatives code to stop speculative
execution of prefetched instructions because we are potentially changing
them and don't want to execute stale bytes.
What it does on most machines is call CPUID which is a serializing
instruction. And that's expensive.
However, the instruction cache is serialized when we're on the local CPU
and are changing the data through the same virtual address. So then, we
don't need the serializing CPUID but a simple control flow change. Last
being accomplished with a CALL/RET which the noinline causes.

There is a feature in Hyper-V ('Debug-VM --InjectNonMaskableInterrupt')
which injects NMI to the guest. We may want to crash the guest and do kdump
on this NMI by enabling unknown_nmi_panic. To make kdump succeed we need to
allow the kdump kernel to re-establish VMBus connection so it will see
VMBus devices (storage, network,..).
To properly unload VMBus making it possible to start over during kdump we
need to do the following:
- Send an 'unload' message to the hypervisor. This can be done on any CPU
so we do this the crashing CPU.
- Receive the 'unload finished' reply message. WS2012R2 delivers this
message to the CPU which was used to establish VMBus connection during
module load and this CPU may differ from the CPU sending 'unload'.
Receiving a VMBus message means the following:
- There is a per-CPU slot in memory for one message. This slot can in
theory be accessed by any CPU.
- We get an interrupt on the CPU when a message was placed into the slot.
- When we read the message we need to clear the slot and signal the fact
to the hypervisor. In case there are more messages to this CPU pending
the hypervisor will deliver the next message. The signaling is done by
writing to an MSR so this can only be done on the appropriate CPU.
To avoid doing cross-CPU work on crash we have vmbus_wait_for_unload()
function which checks message slots for all CPUs in a loop waiting for the
'unload finished' messages. However, there is an issue which arises when
these conditions are met:
- We're crashing on a CPU which is different from the one which was used
to initially contact the hypervisor.
- The CPU which was used for the initial contact is blocked with interrupts
disabled and there is a message pending in the message slot.
In this case we won't be able to read the 'unload finished' message on the
crashing CPU. This is reproducible when we receive unknown NMIs on all CPUs
simultaneously: the first CPU entering panic() will proceed to crash and
all other CPUs will stop themselves with interrupts disabled.
The suggested solution is to handle unknown NMIs for Hyper-V guests on the
first CPU which gets them only. This will allow us to rely on VMBus
interrupt handler being able to receive the 'unload finish' message in
case it is delivered to a different CPU.
The issue is not reproducible on WS2016 as Debug-VM delivers NMI to the
boot CPU only, WS2012R2 and earlier Hyper-V versions are affected.

Aside from being excessively slow, CPUID is problematic: Linux runs
on a handful of CPUs that don't have CPUID. Use IRET-to-self
instead. IRET-to-self works everywhere, so it makes testing easy.
For reference, On my laptop, IRET-to-self is ~110ns,
CPUID(eax=1, ecx=0) is ~83ns on native and very very slow under KVM,
and MOV-to-CR2 is ~42ns.
While we're at it: sync_core() serves a very specific purpose.

This reverts commit ed68d7e9b9.
The patch wasn't quite correct -- there are non-Intel (and hence
non-486) CPUs that we support that don't have CPUID. Since we no
longer require CPUID for sync_core(), just revert the patch.
I think the relevant CPUs are Geode and Elan, but I'm not sure.
In principle, we should try to do better at identifying CPUID-less
CPUs in early boot, but that's more complicated.

Somehow, CONFIG_PARAVIRT=n convinces gcc to change the

129: 55 push %rbp
12a: 48 89 e5 mov %rsp,%rbp

12d: 41 ff 72 f8 pushq -0x8(%r10)
131: 55 push %rbp
132: 48 89 e5 mov %rsp,%rbp
This is an unusual pattern which aligns rsp (though in this case it's
already aligned) and saves the start_cpu() return address again on the
stack before storing the frame pointer.
The unwinder assumes the last stack frame header is at a certain offset,
but the above code breaks that assumption, resulting in the following

ca not possible have i8042 (as is the case with Inrel MID platform),
firmware (such as ACPI) reports that i8042 is absent from the device,

When CONFIG_PARAVIRT is selected, cpuid() becomes a call. Since
for 32-bit kernels load_ucode_amd_bsp() is executed before paging
is enabled the call cannot be completed (as kernel virtual addresses
are not reachable yet).
Use native_cpuid() instead which is an asm wrapper for the CPUID
instruction.

Doing so is completely void of sense for multiple reasons so prevent
it. Set dis_ucode_ldr to true and thus disable the microcode loader by
default to address xen pv guests which execute the AP path but not the
BSP path.
By having it turned off by default, the APs won't run into the loader
either.
Also, check CPUID(1).ECX[31] which hypervisors set. Well almost, not the
xen pv one. That one gets the aforementioned "fix".
Also, improve the detection method by caching the final decision whether
to continue loading in dis_ucode_ldr and do it once on the BSP. The APs
then simply test that value.

Make it simply return bool to denote whether it found a container or not
and return the pointer to the container and its size in the handed-in

Pull timer updates from Thomas Gleixner:
"This is the last functional update from the tip tree for 4.10. It got
delayed due to a newly reported and anlyzed variant of BIOS bug and
the resulting wreckage:
- Seperation of TSC being marked realiable and the fact that the
platform provides the TSC frequency via CPUID/MSRs and making use
for it for GOLDMONT.
- TSC adjust MSR validation and sanitizing:
The TSC adjust MSR contains the offset to the hardware counter. The
sum of the adjust MSR and the counter is the TSC value which is
read via RDTSC.
On at least two machines from different vendors the BIOS sets the
TSC adjust MSR to negative values. This happens on cold and warm
boot. While on cold boot the offset is a few milliseconds, on warm
boot it basically compensates the power on time of the system. The
BIOSes are not even using the adjust MSR to set all CPUs in the
package to the same offset. The offsets are different which renders
the TSC unusable,
What's worse is that the TSC deadline timer has a HW feature^Wbug.
It malfunctions when the TSC adjust value is negative or greater
equal 0x80000000 resulting in silent boot failures, hard lockups or
non firing timers. This looks like some hardware internal 32/64bit
issue with a sign extension problem. Intel has been silent so far
on the issue.
The update contains sanity checks and keeps the adjust register
within working limits and in sync on the package.
As it looks like this disease is spreading via BIOS crapware, we
need to address this urgently as the boot failures are hard to
debug for users"

Adjust value 0x80000000 and other values larger than that render the TSC
deadline timer disfunctional.
We have not yet any information about this from Intel, but experimentation
clearly proves that this is a 32/64 bit and sign extension issue.
If adjust values larger than that are actually required, which might be the
case for physical CPU hotplug, then we need to disable the deadline timer
on the affected package/CPUs and use the local APIC timer instead.
That requires some surgery in the APIC setup code, so we just limit the
ADJUST register value into the known to work range for now and revisit this
when Intel comes forth with proper information.

Currently bd_addr lives in mm_struct, which is otherwise architecture
independent. Architecture-specific data is supposed to live within
mm_context_t (itself contained in mm_struct).
Other x86-specific context like the pkey accounting data lives in
mm_context_t, and there's no readon the MPX data can't also live there.
So as to keep the arch-specific data togather, and to set a good example
for others, this patch moves bd_addr into x86's mm_context_t.

The semantics of the old tile __write_once are the same as the
newer generic __ro_after_init, so rename them all and get rid
of the tile-specific version.
This does not enable actual support for __ro_after_init,
which had been dropped from the tile architecture before the
initial upstreaming was done, since we had at that time switched
to using 16MB huge pages to map the kernel.

This directive was put in the kernel source before the "pragma

is upstreamed. This avoids a warning when building the kernel.
This routine is not on a hot path in any case, so the extra
optimization here was mostly just for its own sake.

* A multiplication for the size determination of a memory allocation
indicated that an array data structure should be processed.
Thus use the corresponding function "kmalloc_array".
* Replace the specification of a data type by a pointer dereference
to make the corresponding size determination a bit safer according to
the Linux coding style convention.

Highlights include:
- Support for the kexec_file_load() syscall, which is a prereq for secure and

- Prevent kernel execution of userspace on P9 Radix (similar to SMEP/PXN).
- Sort the exception tables at build time, to save time at boot, and store
them as relative offsets to save space in the kernel image & memory.
- Allow building the kernel with thin archives, which should allow us to build
an allyesconfig once some other fixes land.
- Build fixes to allow us to correctly rebuild when changing the kernel endian
from big to little or vice versa.
- Plumbing so that we can avoid doing a full mm TLB flush on P9 Radix.
- Initial stack protector support (-fstack-protector).
- Support for dumping the radix (aka. Linux) and hash page tables via debugfs.
- Fix an oops in cxl coredump generation when cxl_get_fd() is used.

Pull m ore s390 updates from Martin Schwidefsky:
"Over 95% of the changes in this pull request are related to the zcrypt
driver. There are five improvements for zcrypt: the ID for the CEX6
cards is added, workload balancing and multi-domain support are
introduced, the debug logs are overhauled and a set of tracepoints is
added.
Then there are several patches in regard to inline assemblies. One
compile fix and several missing memory clobbers. As far as we can tell
the omitted memory clobbers have not caused any breakage.
A small change to the PCI arch code, the machine can tells us how big
the function measurement blocks are. The PCI function measurement will
be disabled for a device if the queried length is larger than the
allocated size for these blocks.
And two more patches to correct five printk messages.
That is it for s390 in regard to the 4.10 merge window. Happy holidays"

This includes the new virtio crypto device, and fixes all over the
place. In particular enabling endian-ness checks for sparse builds
found some bugs which this fixes. And it appears that everyone is in
agreement that disabling endian-ness sparse checks shouldn't be
necessary any longer.
So this enables them for everyone, and drops __CHECK_ENDIAN__
and __bitwise__ APIs.
IRQ handling in virtio has been refactored somewhat, the
larger switch to IRQ_SHARED will have to wait as
it proved too aggressive.

this time:
- Huawei Nexus 6P (Angler) mobile phone
- LG Nexus 5x (Bullhead) mobile phone
- Nexbox A1 and A95X Android TV boxes
- Pine64 development board based on Allwinner A64
- Globalscale Marvell ESPRESSOBin community board based on Armada 3700
- Renesas "R-Car Starter Kit Pro" (M3ULCB) low-cost automotive board

Pull ARM 64-bit DT updates from Arnd Bergmann:
"A couple of interesting new SoC platforms are now supported, these are
the respective DTS sources:
- Samsung Exynos5433 mobile phone platform, including an (almost)
fully supported phone reference board.
- Hisilicon Hip07 server platform and D05 board, the latest iteration
of their product line, now with 64 Cortex-A72 cores across two
sockets.
- Allwinner A64 SoC, the first 64-bit chip from their "sunxi" product
line, used in Android tablets and ultra-cheap development boards
- NXP LS1046A Communication processor, improving on the earlier
LS1043A with faster CPU cores
- Qualcomm MSM8992 (Snapdragon 808) and MSM8994 (Snapdragon 810)
mobile phone SoCs
- Early support for the Nvidia Tegra Tegra186 SoC
- Amlogic S905D is a minor variant of their existing Android consumer
product line
- Rockchip PX5 automotive platform, a close relative of their popular
rk3368 Android tablet chips
Aside from the respective evaluation platforms for the above chips,
there are only a few consumer devices and boards added this time:
- Huawei Nexus 6P (Angler) mobile phone
- LG Nexus 5x (Bullhead) mobile phone
- Nexbox A1 and A95X Android TV boxes
- Pine64 development board based on Allwinner A64
- Globalscale Marvell ESPRESSOBin community board based on Armada 3700
- Renesas "R-Car Starter Kit Pro" (M3ULCB) low-cost automotive board
For the existing platforms, we get bug fixes and new peripheral
support for Juno, Renesas, Uniphier, Amlogic, Samsung, Broadcom,
Rockchip, Berlin, and ZTE"

Lots of changes as usual, so I'm trying to be brief here. Most of the
new hardware support has the respective driver changes merged through
other trees or has had it available for a while, so this is where things
come together.
We get a DT descriptions for a couple of new SoCs, all of them variants
of other chips we already support, and usually coming with a new
evaluation board:
- Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
- Qualcomm MDM9615 LTE baseband
- NXP imx6ull, the latest and smallest i.MX6 application processor variant
- Renesas RZ/G (r8a7743 and r8a7745) application processors
- Rockchip PX3, a variant of the rk3188 chip used in Android tablets
- Rockchip rk1108 single-core application processor
- ST stm32f746 Cortex-M7 based microcontroller
- TI DRA71x automotive processors
These are commercially available consumer platforms we now support:
- Motorola Droid 4 (xt894) mobile phone
- Rikomagic MK808 Android TV stick based on Rockchips rx3066
- Cloud Engines PogoPlug v3 based on OX820
- Various Broadcom based wireless devices:
- Netgear R8500 router
- Tenda AC9 router
- TP-LINK Archer C9 V1
- Luxul XAP-1510 Access point
- Turris Omnia open hardware router based on Armada 385
And a couple of new boards targeted at developers, makers
or industrial integration:
- Macnica Sodia development platform for Altera socfpga (Cyclone V)
- MicroZed board based on Xilinx Zynq FPGA platforms
- TOPEET itop/elite based on exynos4412
- WP8548 MangOH Open Hardware platform for IOT, based on
Qualcomm MDM9615
- NextThing CHIP Pro gadget
- NanoPi M1 development board
- AM571x-IDK industrial board based on TI AM5718
- i.MX6SX UDOO Neo
- Boundary Devices Nitrogen6_SOM2 (i.MX6)
- Engicam i.CoreM6
- Grinn i.MX6UL liteSOM/liteBoard
- Toradex Colibri iMX6 module
Other changes:
- added peripherals on renesas, davinci, stm32f429, uniphier, sti,
mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
mvebu, allwinner, broadcom, exynos, zynq
- Continued fixes for W=1 dtc warnings
- The old STiH415/416 SoC support gets removed, these never made it into
products and have served their purpose in the kernel as a template
for teh newer chips from ST
- The exynos4415 dtsi file is removed as nothing uses it.
- Intel PXA25x can now be booted using devicetree
Conflicts:
arch/arm/boot/dts/r8a*.dtsi: a node was added

Changes to platform code for 64-bit ARM platforms. We are not adding
any new platforms that require code or Kconfig changes this time, so
it's basically just defconfig changes to enable support for more
drivers used on the existing platforms.
This is mainly interesting for the Raspberry Pi 3, which should
now work much better with the default build.

As usual, we queue up a few fixes that don't seem urgent enough to go in
through -rc, or that just came a little too late given their size.
The zx fixes make the platform finally boot on real hardware, the
davinci and imx31 get the DT support working better for some of
the machines that are still normally used with classic board files.
One tegra fix is important for new bootloader versions, but the
bug has been around for a while without anyone noticing.
The other changes are mostly cosmetic.

Pull ARM SoC non-urgent fixes from Arnd Bergmann:
"As usual, we queue up a few fixes that don't seem urgent enough to go
in through -rc, or that just came a little too late given their size.
The zx fixes make the platform finally boot on real hardware, the
davinci and imx31 get the DT support working better for some of the
machines that are still normally used with classic board files. One
tegra fix is important for new bootloader versions, but the bug has
been around for a while without anyone noticing.
The other changes are mostly cosmetic"

it was just a matter of days before 4.9 would be released, and I
figured I would just submit them in the merge window. They are old

Roland reported that his DELL T5810 sports a value add BIOS which
completely wreckages the TSC. The squirmware [(TM) Ingo Molnar] boots with
random negative TSC_ADJUST values, different on all CPUs. That renders the
TSC useless because the sycnchronization check fails.
Roland tested the new TSC_ADJUST mechanism. While it manages to readjust
the TSCs he needs to disable the TSC deadline timer, otherwise the machine
just stops booting.
Deeper investigation unearthed that the TSC deadline timer is sensitive to
the TSC_ADJUST value. Writing TSC_ADJUST to a negative value results in an
interrupt storm caused by the TSC deadline timer.
This does not make any sense and it's hard to imagine what kind of hardware
wreckage is behind that misfeature, but it's reliably reproducible on other
systems which have TSC_ADJUST and TSC deadline timer.
While it would be understandable that a big enough negative value which
moves the resulting TSC readout into the negative space could have the
described effect, this happens even with a adjust value of -1, which keeps
the TSC readout definitely in the positive space. The compare register for
the TSC deadline timer is set to a positive value larger than the TSC, but
despite not having reached the deadline the interrupt is raised
immediately. If this happens on the boot CPU, then the machine dies
silently because this setup happens before the NMI watchdog is armed.
Further experiments showed that any other adjustment of TSC_ADJUST works as
expected as long as it stays in the positive range. The direction of the
adjustment has no influence either. See the lkml link for further analysis.
Yet another proof for the theory that timers are designed by janitors and
the underlying (obviously undocumented) mechanisms which allow BIOSes to
wreckage them are considered a feature. Well done Intel - NOT!
To address this wreckage add the following sanity measures:
- If the TSC_ADJUST value on the boot cpu is not 0, set it to 0
- If the TSC_ADJUST value on any cpu is negative, set it to 0
- Prevent the cross package synchronization mechanism from setting negative
TSC_ADJUST values.

prefill_possible_map() reinitializes the cpu_possible_map by setting the
possible cpu bits and clearing all other bits up to NR_CPUS.
This is technically always correct because cpu_possible_map is statically
allocated and sized NR_CPUS. With CPUMASK_OFFSTACK and DEBUG_PER_CPU_MAPS
enabled the bounds check of cpu masks happens on nr_cpu_ids. nr_cpu_ids is
initialized to NR_CPUS and only limited after the set/clear bit loops have
been executed.
But if the system was booted with "nr_cpus=N" on the command line, where N
is < NR_CPUS then nr_cpu_ids is limited in the parameter parsing function
before prefill_possible_map() is invoked. As a consequence the cpumask
bounds check triggers when clearing the bits past nr_cpu_ids.
Add a helper which allows to reset cpu_possible_map w/o the bounds check
and then set only the possible bits which are well inside bounds.

Implement functions watchdog_nmi_enable and watchdog_nmi_disable to
enable/disable nmi watchdog. Sparc uses arch specific nmi watchdog
handler. Currently, we do not have a way to enable/disable nmi watchdog
dynamically. With these patches we can enable or disable arch specific
nmi watchdogs using proc or sysctl interface.
Example commands.
To enable: echo 1 > /proc/sys/kernel/nmi_watchdog
To disable: echo 0 > /proc/sys/kernel/nmi_watchdog
It can also achieved using the sysctl parameter kernel.nmi_watchdog

Patch series "Add support for DMA writable pages being writable by the
network stack", v3.
The first 19 patches in the set add support for the DMA attribute
DMA_ATTR_SKIP_CPU_SYNC on multiple platforms/architectures. This is
needed so that we can flag the calls to dma_map/unmap_page so that we do
not invalidate cache lines that do not currently belong to the device.
Instead we have to take care of this in the driver via a call to
sync_single_range_for_cpu prior to freeing the Rx page.
Patch 20 adds support for dma_map_page_attrs and dma_unmap_page_attrs so
that we can unmap and map a page using the DMA_ATTR_SKIP_CPU_SYNC
attribute.
Patch 21 adds support for freeing a page that has multiple references
being held by a single caller. This way we can free page fragments that
were allocated by a given driver.
The last 2 patches use these updates in the igb driver, and lay the
groundwork to allow for us to reimplement the use of build_skb.
This patch (of 23):
This change allows us to pass DMA_ATTR_SKIP_CPU_SYNC which allows us to
avoid invoking cache line invalidation if the driver will just handle it
later via a sync_for_cpu or sync_for_device call.

Currently in x86_64, the symbol address of phys_base is exported to
vmcoreinfo. Dave Anderson complained this is really useless for his
Crash implementation. Because in user-space utility Crash and
Makedumpfile which exported vmcore information is mainly used for, value
of phys_base is needed to covert virtual address of exported kernel
symbol to physical address. Especially init_level4_pgt, if we want to
access and go over the page table to look up a PA corresponding to VA,
firstly we need calculate
page_dir = SYMBOL(init_level4_pgt) - __START_KERNEL_map + phys_base;
Now in Crash and Makedumpfile, we have to analyze the vmcore elf program
header to get value of phys_base. As Dave said, it would be preferable
if it were readily availabl in vmcoreinfo rather than depending upon the
PT_LOAD semantics.
Hence in this patch change to export the value of phys_base instead of
its virtual address.
And people also complained that KERNEL_IMAGE_SIZE exporting is x86_64
only, should be moved into arch dependent function
arch_crash_save_vmcoreinfo. Do the moving in this patch.

This reverts commit 0549a3c02e ("kdump, vmcoreinfo: report memory
sections virtual addresses").
Commit 0549a3c02e tells the userspace utility makedumpfile the
randomized base address of these memmory sections when mm kaslr is
enabled. However the following patch "kexec: export the value of
phys_base instead of symbol address" makes makedumpfile not need these
addresses any more.
Besides we should use VMCOREINFO_NUMBER to export the value of the
variable so that we can use the existing number_table mechanism of
Makedumpfile to fetch it. So revert it now. If needed we can add it
later.

Pull namespace updates from Eric Biederman:
"After a lot of discussion and work we have finally reachanged a basic
understanding of what is necessary to make unprivileged mounts safe in
the presence of EVM and IMA xattrs which the last commit in this
series reflects. While technically it is a revert the comments it adds
are important for people not getting confused in the future. Clearing
up that confusion allows us to seriously work on unprivileged mounts
of fuse in the next development cycle.
The rest of the fixes in this set are in the intersection of user
namespaces, ptrace, and exec. I started with the first fix which
started a feedback cycle of finding additional issues during review
and fixing them. Culiminating in a fix for a bug that has been present
since at least Linux v1.0.
Potentially these fixes were candidates for being merged during the rc
cycle, and are certainly backport candidates but enough little things
turned up during review and testing that I decided they should be
handled as part of the normal development process just to be certain
there were not any great surprises when it came time to backport some
of these fixes"

UBD at present is extremely slow because it handles only
one request at a time in the IO thread and IRQ handler.
The single request at a time is replaced by handling multiple
requests as well as necessary workarounds for short reads/writes.
Resulting performance improvement in disk IO - 30%

ARC HS Cores support configurable multiple interrupt priorities of upto
16 levels. In commit dec2b2849c ("ARCv2: intc: Allow interruption by
lowest priority interrupt") we switched to 15 which seems a bit
excessive given that there would be rare hardware implementing so many
preemption levels AND running Linux. It would seem that 2 levels will be
more common so switch to 1 as the default priority level. This will be
the "lower" priority level saving 0 for implementing NMI style support.
This scheme also works in systems with more than 2 prioity levels as
well.

We have a couple of inline assemblies like memchr() and strlen() that
read from memory, but tell the compiler only they need the addresses
of the strings they access.
This allows the compiler to omit the initialization of such strings
and therefore generate broken code. Add the missing memory barrier to
all string related inline assemblies to fix this potential issue. It
looks like the compiler currently does not generate broken code due to
these bugs.

The qsi inline assembly takes an initialized "cc" variable as output
operand but specifies it as write-to operand only instead of
read/write operand. This allows the compiler to omit the
initialization, which in fact it also does (gcc 6.1).
Use the "+" constraint modifier to fix this. In addition also use the
Q constraint to specify the hws_qsi_info_block memory location, so the
compiler can generate slightly better code. Also get rid of the cc
clobber since none of the instructions within the inline assembly
modify the condition code.

This patch introduces tracepoint definitions and tracepoint
event invocations for the s390 zcrypt device.
Currently there are just two tracepoint events defined.
An s390_zcrypt_req request event occurs as soon as the
request is recognized by the zcrypt ioctl function. This
event may act as some kind of request-processing-starts-now
indication.
As late as possible within the zcrypt ioctl function there
occurs the s390_zcrypt_rep event which may act as the point
in time where the request has been processed by the kernel
and the result is about to be transferred back to userspace.
The glue which binds together request and reply event is the
ptr parameter, which is the local buffer address where the
request from userspace has been stored by the ioctl function.
The main purpose of this zcrypt tracepoint patch is to get
some data for performance measurements together with
information about the kind of request and on which card and
queue the request has been processed. It is not an ffdc
interface as there is already code in the zcrypt device
driver to serve the s390 debug feature interface.

Commit 4fd06960f1 ("Use the new x86 setup code for i386") introduced a
reference to the make variable LINUX_INCLUDE. That reference got moved
around a bit and copied twice and now there are three references to it.
There has never been a definition of that variable. (Presumably that is
because it started out as a mistyped reference to LINUXINCLUDE.) So this
reference has always been an empty string. Let's remove it before it
spreads any further.

Add these declarations for x86, and an architecture-independent file that

Here's the new driver core patches for 4.10-rc1.
Big thing here is the nice addition of "functional dependencies" to the
driver core. The idea has been talked about for a very long time, great
job to Rafael for stepping up and implementing it. It's been tested for
longer than the 4.9-rc1 date, we held off on merging it earlier in order
to feel more comfortable about it.
Other than that, it's just a handful of small other patches, some good
cleanups to the mess that is the firmware class code, and we have a test
driver for the deferred probe logic.
All of these have been in linux-next for a while with no reported
issues.

Pull block layer updates from Jens Axboe:
"This is the main block pull request this series. Contrary to previous
release, I've kept the core and driver changes in the same branch. We
always ended up having dependencies between the two for obvious
reasons, so makes more sense to keep them together. That said, I'll
probably try and keep more topical branches going forward, especially
for cycles that end up being as busy as this one.
The major parts of this pull request is:
- Improved support for O_DIRECT on block devices, with a small
private implementation instead of using the pig that is
fs/direct-io.c. From Christoph.
- Request completion tracking in a scalable fashion. This is utilized
by two components in this pull, the new hybrid polling and the
writeback queue throttling code.
- Improved support for polling with O_DIRECT, adding a hybrid mode
that combines pure polling with an initial sleep. From me.
- Support for automatic throttling of writeback queues on the block
side. This uses feedback from the device completion latencies to
scale the queue on the block side up or down. From me.
- Support from SMR drives in the block layer and for SD. From Hannes
and Shaun.
- Multi-connection support for nbd. From Josef.
- Cleanup of request and bio flags, so we have a clear split between
