Merge tag 'rodata-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull rodata updates from Kees Cook:
"This renames the (now inaccurate) DEBUG_RODATA and related
SET_MODULE_RONX configs to the more sensible STRICT_KERNEL_RWX and
STRICT_MODULE_RWX"
* tag 'rodata-v4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
arch: Rename CONFIG_DEBUG_RODATA and CONFIG_DEBUG_MODULE_RONX
arch: Move CONFIG_DEBUG_RODATA and CONFIG_SET_MODULE_RONX to be common
Core changes:
- Switch the generic pin config argument from 16 to 24 bits,
only use 8 bits for the configuration type. We might need to
encode more information about a certain setting than we need
to encode different generic settings.
- Add a cross-talk API to the pin control GPIO back-end,
utilizing pinctrl_gpio_set_config() from GPIO drivers that
want to set up a certain pin configuration in the back-end.
This also includes the .set_config() refactoring of the
GPIO chips, so that they pass a generic configuration for
things like debouncing and single ended (typically open
drain). This change has also been merged in an immutable
branch to the GPIO tree.
- Take hogs with a delayed work, so that we finalize probing
a pin controller before trying to get any hogs.
- For pin controllers putting all group and function definitions
into the device tree, we now have generic code to deal with
this and it is used in two drivers so far.
- Simplifications of the pin request conflict check.
- Make dt_free_map() optional.
Updates to drivers:
- pinctrl-single now use the generic helpers to generate dynamic
group and function tables from the device tree.
- Texas Instruments IOdelay configuration driver add-on to
pinctrl-single.
- i.MX: use radix trees to store groups and functions, use the new
generic group and function helpers to manage them.
- Intel: add support for hardware debouncing and 1K pull-down.
New subdriver for the Gemini Lake SoC.
- Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
- Aspeed: use syscon cross-dependencies to set up related bits in
the LPC host controller and display controller.
- Aspeed: finalize G4 and G5 support. Fix mux configuration on
GPIOs. Add banks Y, Z, AA, AB and AC.
- AMD: support additional GPIO.
- STM32: set this controller to strict muxing mode.
STM32H743 MCU support.
- Allwinner sunxi: deep simplifications on how to support
subvariants of SoCs without adding to much SoC-specific data
for each subvariant, especially for sun5i variants. New driver
for V3s SoCs. New driver for the H5 SoC. Support A31/A31s
variants with the new variant framework.
- Mvebu: simplifications to use a MMIO and regmap abstraction.
New subdrivers for the 98DX3236, 98DX5241 SoCs.
- Samsung Exynos: delete Exynos4415 support. Add crosstalk to the
SoC driver to access regmaps. Add infrastructure for pin-bank
retention control. Clean out the pin retention control from
arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly
in the Samsung pin control driver(s).
- Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
- Qualcomm: use raw spinlock variants: this makes the qualcomm
driver realtime-safe.

Pull exception table module split from Paul Gortmaker:
"Final extable.h related changes.
This completes the separation of exception table content from the
module.h header file. This is achieved with the final commit that
removes the one line back compatible change that sourced extable.h
into the module.h file.
The commits are unchanged since January, with the exception of a
couple Acks that came in for the last two commits a bit later. The
changes have been in linux-next for quite some time[1] and have got
widespread arch coverage via toolchains I have and also from
additional ones the kbuild bot has.
Maintaners of the various arch were Cc'd during the postings to
lkml[2] and informed that the intention was to take the remaining arch
specific changes and lump them together with the final two non-arch
specific changes and submit for this merge window.
The ia64 diffstat stands out and probably warrants a mention. In an
earlier review, Al Viro made a valid comment that the original header
separation of content left something to be desired, and that it get
fixed as a part of this change, hence the larger diffstat"

Pull power management updates from Rafael Wysocki:
"The majority of changes go into the Operating Performance Points (OPP)
framework and cpufreq this time, followed by devfreq and some
scattered updates all over.
The OPP changes are mostly related to switching over from RCU-based
synchronization, that turned out to be overly complicated and
problematic, to reference counting using krefs.
In the cpufreq land there are core cleanups, documentation updates, a
new driver for Broadcom BMIPS SoCs, a new cpufreq-dt sub-driver for TI
SoCs that require special handling, ARM64 SoCs support for the qoriq
driver, intel_pstate updates, powernv driver update and assorted
fixes.
The devfreq changes are mostly fixes related to the sysfs interface
and some Exynos drivers updates.
Apart from that, the cpuidle menu governor will support per-CPU PM QoS
constraints for the wakeup latency now, some bugs in the wakeup IRQs
framework are fixed, the generic power domains framework should handle
asynchronous invocations of *noirq suspend/resume callbacks from now
on, the analyze_suspend.py script is updated and there is a new tool
for intel_pstate diagnostics.

Pull perf updates from Ingo Molnar:
"On the kernel side the main changes in this cycle were:
- Add Intel Kaby Lake CPU support (Srinivas Pandruvada)
- AMD uncore driver updates for fam17 (Janakarajan Natarajan)
- Intel/PT updates and core events optimizations and cleanups
(Alexander Shishkin)
- cgroups events fixes (David Carrillo-Cisneros)
- kprobes improvements (Masami Hiramatsu)
- ... plus misc fixes and updates.
On the tooling side the main changes were:
- Support clang build in tools/{perf,lib/{bpf,traceevent,api}} with
CC=clang, to, for instance, take advantage of better warnings
(Arnaldo Carvalho de Melo):
- Introduce the 'delta-abs' 'perf diff' compute method, that orders
the histogram entries by the absolute value of the percentage delta
for a function in two perf.data files, i.e. the functions that
changed the most (increase or decrease in samples) comes first
(Namhyung Kim)
- Add support for parsing Intel uncore vendor event files and add
uncore vendor events for the Intel server processors (Haswell,
Broadwell, IvyBridge), Xeon Phi (Knights Landing) and Broadwell DE
(Andi Kleen)
- Introduce 'perf ftrace' a perf front end to the kernel's ftrace
function and function_graph tracer, defaulting to the
"function_graph" tracer, more work will be done in reviving this
effort, forward porting it from its initial patch submission
(Namhyung Kim)
- Add 'e' and 'c' hotkeys to expand/collapse call chains for a single
hist entry in the 'perf report' and 'perf top' TUI (Jiri Olsa)
- Account thread wait time (off CPU time) separately: sleep, iowait
and preempt, based on the prev_state of the last event, show the
breakdown when using "perf sched timehist --state" (Namhyumg Kim)
- Add more triggers to switch the output file (perf.data.TIMESTAMP).
Now, in addition to switching to a different output file when
receiving a SIGUSR2, one can also specify file size and time based
triggers:
perf record -a --switch-output=signal
is equivalent to what we had before:
perf record -a --switch-output
While we can also ask for the file to be "sliced" by size, taking
into account that that will happen only when we get woken up by the
kernel, i.e. one has to take into account the --mmap-pages (the
size of the perf mmap ring buffer):
perf record -a --switch-output=2G
will break the perf.data output into multiple files limited to 2GB
of samples, right when generating the output.
For time based samples, alert() will be used, so to have 1 minute
limited perf.data output files:
perf record -a --switch-output=1m
(Jiri Olsa)
- Improve 'perf trace' (Arnaldo Carvalho de Melo)
- 'perf kallsyms' toy tool to look for extended symbol information on
the running kernel and demonstrate the machine/thread/symbol APIs
for use in other tools, such as 'perf probe' (Arnaldo Carvalho de
Melo)
- ... plus tons of other changes, see the shortlog and Git log for
details"

Two more bugfixes that came in during this week:
- one defconfig change to enable a vital driver used on some Qualcomm
based phones. This was already queued for 4.11, but the maintainer
asked to have it in 4.10 after all.
- One regression fix for the reset controller framework, this got
broken by a typo in the 4.10 merge window.

One fix from Paul, we can not use the radix MMU under a hypervisor for now.
Although the current code checks if the processor supports radix, that is not
sufficient.

One of the last remaining failures in kernelci.org is for a gcc bug:
drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: error: insn does not satisfy its constraints:
drivers/net/ethernet/qlogic/qlge/qlge_main.c:4819:1: internal compiler error: in extract_constrain_insn, at recog.c:2190
This is apparently broken in gcc-6 but fixed in gcc-7, and I cannot
reproduce the problem here. However, it is clear that ip27_defconfig
does not actually need this driver as the platform has only PCI-X but
not PCIe, and the qlge adapter in turn is PCIe-only.
The driver was originally enabled in 2010 along with lots of other
drivers.

Early clock API pic32_get_pbclk() is defined in early_clk.c and used by
time.c and early_console.c. When CONFIG_EARLY_PRINTK isn't set,
early_clk.c isn't compiled and time.c fails to link.
Fix it by compiling early_clk.c always. Also sort files in alphabetical
order.

Disabling ethernet during reboot (only to enable it again when the
ethernet driver attaches) can put the chip into a faulty state where it
corrupts the header of all incoming packets.
This happens if packets arrive during the time window where the core is
disabled, and it can be easily reproduced by rebooting while sending a
flood ping to the broadcast address.

If copy_from_user is called with a large buffer (>= 128 bytes) and the
userspace buffer refers partially to unreadable memory, then it is
possible for Octeon's copy_from_user to report the wrong number of bytes
have been copied. In the case where the buffer size is an exact multiple
of 128 and the fault occurs in the last 64 bytes, copy_from_user will
report that all the bytes were copied successfully but leave some
garbage in the destination buffer.
The bug is in the main __copy_user_common loop in octeon-memcpy.S where
in the middle of the loop, src and dst are incremented by 128 bytes. The
l_exc_copy fault handler is used after this but that assumes that
"src < THREAD_BUADDR($28)". This is not the case if src has already been
incremented.
Fix by adding an extra fault handler which rewinds the src and dst
pointers 128 bytes before falling though to l_exc_copy.
Thanks to the pwritev test from the strace test suite for originally
highlighting this bug!

len = 80, proto = 17, sum = 0x7eae049d there will be a carry when
folding the intermediate 64 bit checksum to 32 bit but the code doesn't
add the carry back to the one's complement sum, thus an incorrect result
