Cayman and trinity allow for variable sized VM page
tables, but SI requires that all page tables be the
same size. The current code assumes variablely sized
VM page tables so SI may end up with part of each page
table overlapping with other memory which could end
up being interpreted by the VM hw as garbage.
Change the code to better accomodate SI. Allocate enough
space for at least 2 full page tables and always set
last_pfn to max_pfn on SI so each VM is backed by a full
page table. This limits us to only 2 VMs active at any
given time on SI. This will be rectified and the code can
be reunified once we move to two level page tables.

The correct behavior is to program the interrupt coalescing regs
(RXICr/TXICr) in accordance with the Rx/Tx Q's "rx/txcoalescing"
flag. That is, if the coalescing flag is 0 for a given Rx/Tx queue
then the corresponding coalescing register should be cleared.
This behavior is correctly implemented for the single-queue mode
(SQ_SG_MODE), but not for the multi-queue mode (MQ_MG_MODE).
This fixes the later case.

Commit e978aa7d7d ( cpuidle: Move
dev->last_residency update to driver enter routine; remove dev->last_state)
was breaking suspend on laptops, as reported in the below link
- https://lkml.org/lkml/2011/11/11/164
This was fixed in commit 3439a8da16
(ACPI / cpuidle: Remove acpi_idle_suspend (to fix suspend regression)
by removing acpi_idle_suspend flag.
- https://lkml.org/lkml/2011/11/14/74
But this did fix did not work on all systems
as Suspend/resume regression was reported on Lenovo S10-3
recently by Dave.
- https://lkml.org/lkml/2012/5/27/115
It looked like with commit e978aa7d broke suspend and
with commit 3439a8da resume was not working with acpi_idle driver.
This patch fixes the regression that caused this issue
in the first place. acpi_idle_suspend flag is essential on
some x86 systems to prevent the cpus from going to deeper C-states
when suspend is triggered ( commit b04e7bdb98 )
So reverting the commit 3439a8da is essential.
By default, irqs are disabled in cpu_idle arch specific call
and re-enabled in idle state return path . During suspend,
the acpi_idle_suspend flag is set, which
prevents the cpus from going to deeper idle states,
it is essential to enabling the irqs in this return path too.
To address the suspend issue,
we were not re-enabling the interrupts while returning from
acpi_idle_enter_bm() routine if acpi_idle_suspend flag is set.
and this caused suspend failure.
In addition to the above, to improve the readability of the code,
return of -ENIVAL is replaced with -EBUSY in acpi_idle_suspend
return path. Implying that the system is currently busy when suspend
is in progress, which prevents the cpus from entering deeper C-states.

On some architectures address spaces are set up in a way that this is
not necessary to work properly but on some others (like s390) it is.
Make sure we operate on the user address space to allow copy_xxx_user()
from the vhost_worker() thread by setting it explicitly before calling
use_mm() and revert it after unuse_mm().

It seems that currently GPIO module is not working correctly during idle
when debounce is enabled - the system almost never responds to button
presses (observed on OMAP3530 ES2.1 and OMAP3630 ES1.2 pandora boards).
Even though wakeups are probably working, it seems that the GPIO module
itself is unable to detect input events and generate interrupts.
OMAP35x TRM also states that:
"If the debounce clock is inactive, the debounce cell gates all
input signals and thus cannot be used."
So whenever we are disabling debounce clocks (for PM or other reasons),
be sure the module's debounce feature is disabled too.

FCoE target mode was experiencing issues due to the fact that we were
sending up data frames that were padded to 60 bytes after the DDP logic had
already stripped the frame down to 52 or 56 depending on the use of VLANs.
This was resulting in the FCoE DDP logic having issues since it thought the
frame still had data in it due to the padding.
To resolve this, adding code so that we do not pad FCoE frames prior to
handling them to the stack.

This patch reverts the commit dba3c29ea4.
After bisecting, this commit dba3c29 is found to ruin micro-SD card data
(writing incorrect file, or fs is corrupt after several times mount)
on the beagle-xm revB, and reverting the commit will fix the problem.
Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about
the Auto CMD12 Enable bit.
- SDIO does not support this feature.
- SD card only.
Looks it is not suitable to always enable Auto CMD12 in host controller
driver.
Considered that the commit is not mature enough, so ask to revert it
first.

If multi block write operation fails for SD card, during
error handling we send the SD_APP_SEND_NUM_WR_BLKS (ACMD22)
to know how many blocks were already programmed by card.
But mmc_sd_num_wr_blocks() function which sends the ACMD22
calculates the data timeout value from csd.tacc_ns and
csd.tacc_clks parameters which will be 0 for block addressed
(>2GB cards) SD card. This would result in timeout_ns and
timeout_clks being 0 in the mmc_request passed to host driver.
This means host controller would program its data timeout timer
value with 0 which could result in DATA TIMEOUT errors from
controller.
To fix this issue, mmc_sd_num_wr_blocks() should instead
just call the mmc_set_data_timeout() to calculate the
data timeout value. mmc_set_data_timeout() function
ensures that non zero timeout value is set even for
block addressed SD cards.

nv_two_heads() was never meant to be used outside of pre-nv50 code. The
code checks for >= NV_10 for 2 CRTCs, then downgrades a few specific
chipsets to 1 CRTC based on (pci_device & 0x0ff0).
The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which
gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing
memory corruption because there's actually 2 CRTCs..
This switches fbcon to use the CRTC count directly from the mode_config
structure, which will also fix the same issue on Kepler boards which have
4 CRTCs.

Parent clocks for muxes are cached in clk->parents to
avoid frequent lookups, however the cache allocation happens
only during clock registeration and later clk_set_parent()
assumes a cache space available and allocated.
This is not entirely true for platforms which do early clock
registerations wherein the cache allocation using kzalloc
could fail during clock registeration.
Allow cache allocation to happen later as part of clk_set_parent()
to help such cases and avoid crashes assuming a cache being
available.
While here also replace existing kmalloc() with kzalloc()
in the file.

When authentication/association timed out, the driver would
complain bitterly, printing the message
ACTIVATE a non DRIVER active station id ... addr ...
The cause turns out to be that when the AP station is added
but we don't associate, the IWL_STA_UCODE_INPROGRESS is set
but never cleared. This then causes iwl_restore_stations()
to attempt to resend it because it uses the flag internally
and uploads even if it didn't set it itself.
To fix this issue and not upload the station again when it
has already been removed by mac80211, clear the flag after
adding it in case we add it only for association.

ath9k_hw: fix interpretation of the rx KeyMiss flag
This commit used the rx key miss indication to detect packets that were

this bit is not only undefined in the static WEP case, but also for
dynamically allocated WEP keys. This caused a regression when using

This patch fixes the regression by keeping track of which key indexes

Also remove some error logs printed for events that aren't critical and
are normal conditions for some system configurations.
Also check if the device have been properly run-time enabled during

When a device is added to the system at runtime the AMD
IOMMU driver initializes the necessary data structures to
handle translation for it. But it forgets to change the
per-device dma_ops to point to the AMD IOMMU driver. So
mapping actually never happens and all DMA accesses end in
an IO_PAGE_FAULT. Fix this.

Author: Ben Collins <bcollins@ubuntu.com>
from udlfb to udl kms driver.
The driver was not using le16_to_cpu when reading keys from the vendor
descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
being parsed on big-endian systems. This would result in a blank screen
on big-endian CPUs where the DL chips's max mode was smaller than the

This patch (as1560) reverts commit
afff07e61a (usb-storage: Add 090c:1000
to unusal-devs). It is no longer needed, because usb-storage now
tells the sd driver to try READ CAPACITY(10) before READ CAPACITY(16)
for every USB mass-storage device.

Several bug reports have been received recently for USB mass-storage
devices that don't handle READ CAPACITY(16) commands properly. They
report bogus sizes, in some cases becoming unusable as a result.
The bugs were triggered by commit
09b6b51b0b (SCSI & usb-storage: add
flags for VPD pages and REPORT LUNS), which caused usb-storage to stop
overriding the SCSI level reported by devices. By default, the sd
driver will try READ CAPACITY(16) first for any device whose level is
above SCSI_SPC_2.
It seems likely that any device large enough to require the use of
READ CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ
CAPACITY(10) commands properly. Indeed, I don't know of any devices
that don't handle READ CAPACITY(10) properly.
Therefore this patch (as1559) adds a new flag telling the sd driver
to try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag
for every USB mass-storage device. If a device really is larger than
2 TB, sd will fall back to READ CAPACITY(16) just as it used to.
This fixes Bugzilla #43391.

If RMCR is not set, the controller will clear the EDRRR after it received

The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards
are very prone to NETDEV watchdog problems without this change. See
https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance.
I don't know why it *works*. It's depressingly effective though.
For the record:
- the problem may go along IOMMU (AMD-Vi) errors but it really looks
like a red herring.
- the patch sets the RX_MULTI_EN bit. If the 8168c doc is any guide,
the chipset now fetches several Rx descriptors at a time.
- long ago the driver ignored the RX_MULTI_EN bit.
e542a2269f changed the RxConfig
settings. Whatever the problem it's now labeled a regression.
- Realtek's own driver can identify two different 8168evl devices
(CFG_METHOD_16 and CFG_METHOD_17) where the r8169 driver only
sees one. It sucks.

Ignoring interfaces with additional descriptors is not a reliable
method for locating the correct interface on Gobi devices. There
is at least one device where this method fails:
https://bbs.archlinux.org/viewtopic.php?id=143506
The result is that the AT command port (interface #2) is hidden
from qcserial, preventing traditional serial modem usage:

[ 15.570372] qcserial 4-1.6:1.3: Qualcomm USB modem converter detected
[ 15.570430] usb 4-1.6: Qualcomm USB modem converter now attached to ttyUSB1
Use static interface numbers taken from the interface map in
qcserial for all Gobi devices instead:
Gobi 1K USB layout:
0: serial port (doesn't respond)
1: serial port (doesn't respond)
2: AT-capable modem port
3: QMI/net
Gobi 2K+ USB layout:
0: QMI/net
1: DM/DIAG (use libqcdm from ModemManager for communication)
2: AT-capable modem port
3: NMEA
This should be more reliable over all, and will also prevent the
noisy "probe failed" messages. The whitelisting logic is expected
to be replaced by direct interface number matching in 3.6.

After banging my head against this for the past few months, I still
don't see how this could possible race under the premise that once an
irq bit is masked in PM_IMR and reset in PM_IIR it won't show up again
until we unmask it in PM_IMR.
Still, we have reports of this being seen in the wild. Now Bspec has
this little bit of lovely language in the PMIIR register:
Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR":
"For each bit, the IIR can store a second pending interrupt if two or
more of the same interrupt conditions occur before the first condition
is cleared. Upon clearing the interrupt, the IIR bit will momentarily
go low, then return high to indicate there is another interrupt
pending."
Now if we presume that PMIMR only prevent new interrupts from being
queued, we could easily end up masking an interrupt and clearing it,
but the 2nd pending interrupt setting the bit in PMIIR right away
again. Which leads, the next time the irq handler runs, to hitting the
WARN.
Also, no bad side effects of this have ever been reported. And we've
tracked down our issues with the gpu turbo getting stuck to bogus
interrupt generation limits in th RPLIMIT register.
So let's just rip out this WARN as bogus and call it a day. The only
shallow thing here is that this 2-deep irq queue in the hw makes you
wonder how racy the windows irq handler is ...

This patch ensures uniformity in event skb sent by interface code
(USB/PCIe/SDIO) which automatically fixes following bugs.
1) For USB interface, same buffer is reused for receiving cmd and
events from firmware. While handling events, we perform
skb_pull(skb, 4) to remove event header. Corresponding skb_push()
call is missing while submitting the buffer.
2) For PCIe interface, event skb is passed with event header.
Recently added uAP events EVENT_UAP_STA_ASSOC, EVENT_UAP_STA_DEAUTH
will not work for PCIe, as they assume event skb points to event body.

After association, STA will go through eapol handshake with WPS
enabled AP. It's observed that WPS handshake fails with some 11n
AP. The reason for the failure is that the eapol packet is sent
via 11n frame aggregation.
The eapol packet should be sent directly without 11n aggregation.
This patch fixes the problem by adding WPS session control while
dequeuing Tx packets for transmission.

Currently we check the sequence number of last packet received
against start_win. If a sequence hole is detected, start_win is
updated to next sequence number.
Since the rx sequence number is initialized to 0, a corner case
exists when BA setup happens immediately after association. As
0 is a valid sequence number, start_win gets increased to 1
incorrectly. This causes the first packet with sequence number 0
being dropped.
Initialize rx sequence number as 0xffff and skip adjusting
start_win if the sequence number remains 0xffff. The sequence
number will be updated once the first packet is received.

oprofile_perf.c:28: error: variably modified 'perf_events' at file scope
This patch uses NR_CPUs instead of nr_cpumask_bits for the array
initialisation. If this causes space problems in the future, we can
always move to dynamic allocation for the events array.

On a freescale imx6q platform, a hardware phy chip KSZ9021 is
recognized as a KS8001 chip by the current driver like this:
eth0: Freescale FEC PHY driver [Micrel KS8001 or KS8721]
KSZ9021 has phy_id 0x00221610, while KSZ8001 has phy_id
0x0022161a, the current phy_id_mask (0x00fffff0/0x00ffff10) can't
distinguish them. So change phy_id_mask to resolve this problem.
Although the micrel datasheet says that the 4 LSB of phyid2 register
contains the chip revision number and the current driver is designed
to follow this rule, in reality the chip implementation doesn't follow
it.

This patch fixes a potential hole when configuring the cycle counter used to
generate the nanosecond time clock. This clock is based off of the SYSTIME
registers along with the TIMINCA registers. The TIMINCA register determines
the increment to be added to the SYSTIME registers every DMA clock tick. This
register needs to be reconfigured whenever the link-speed changes. However,
the value calculated stays the same when link is down and when link is up.
Misconfiguration can occur if the link status changes due to a reset, which
causes the TIMINCA register to be reset. This reset puts the device in an
unstable state where the SYSTIME registers stop incrementing and the PTP
protocol does not function.
The solution is to double check the TIMINCA value and always reset the value
if the register is zero. This prevents a misconfiguration bug that halts the
PHC.

If the GPIOs used by the MMCI driver are not registered yet when the driver is
probe()d, they can't be used. This happens if the mmci driver is probed before
the respective GPIO controller (e.g. on the LPC32xx EA3250 board, the PCA9532
GPIO controller would be initialized via DT after mmci). Therefore, we defer
mmci in this case.

This reverts commit 092945e11c.
This commit prevents a DP screen from properly training the link.
Oddly enough it works, once the machine has been warm-booted with an
older kernel.
According to DP docs this _should_ have been the right precharge time.
Also, the commit that originally introduces this was just general snb
DP enabling and didn't mention any specific reason for this special
value. Whatever, trust the reporter that this makes things worse and
let's just revert it.

After recent changes HDMI code is ready to be enabled on DCE5. This
patch just changes conditions to execute already present code on DCE5.

The filed object_idr of struct drm_sis_private was introduced with
commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=6de8a748881f1cd9d795454da2b6db616d5ca3d7 .
The idr_init(&dev->object_name_idr) is called instead of
idr_init(&dev_priv->object_idr) by mistake, leaving object_idr
uninitialized. Correct this.
This patch was not tested because of lack of hardware.

The field obejct_idr of struct drm_via_private was introduced with the
commit http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=77ee8f3825054f23b17e9c8f728f061defd86cdc .
In that patch idr_init(&dev->object_name_idr) was called instead of
idr_init(&dev_priv->object_idr) by mistake, leaving the dev_priv->object_idr
uninitialized. To be more exact, the object_idr buffer is filled with zeros
because of kzalloc(), but the dev_priv->object_idr.lock spinlock can cause
system freeze at lib/idr.c:move_to_free_list() when spin_lock_irqsave()
is called on this spinlock.
The patch was tested on Clevo D4J, model D410J laptop, on the following
hardware, without AGP kernel module loaded:

I finally got to test this code a bit more and hit the ttm
no reserved assert, so add the reservations around the pinning.

Not all asics have all rings, so make sure the ring is ready
before attempting to check it in the dynpm work handler.
