Time is nature's way of making sure that everything doesn't happen at once.
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chris Wilson <[email protected]>
commit 3eef8918ff440837f6af791942d8dd07e1a268ee upstream.
By correctly describing the rinbuffers as being in the GTT domain, it
appears that we are more careful with the management of the CPU cache
upon resume and so prevent some coherency issue when submitting commands
to the GPU later. A secondary effect is that the debug logs are then
consistent with the actual usage (i.e. they no longer describe the
ringbuffers as being in the CPU write domain when we are accessing them
through an wc iomapping.)

commit cb05d8dedefa3066bf5d74ef88c6ca6cf4bd1c87 upstream.
Or at least plug another gapping hole. Apparrently hw desingers only
moved the bit field, but did not bother ot re-enumerate the planes
when adding support for a 3rd pipe.
Discovered by i-g-t/flip_test.
This may or may not fix the reference bugzilla, because that one
smells like we have still larger fish to fry.
v2: Fixup the impossible case to catch programming errors, noticed by
Chris Wilson.

From: Emmanuel Grumbach <[email protected]>
commit d6ee27eb13beab94056e0de52d81220058ca2297 upstream.
When we remove a key, we put a key index which was supposed
to tell the fw that we are actually removing the key. But
instead the fw took that index as a valid index and messed
up the SRAM of the device.
This memory corruption on the device mangled the data of
the SCD. The impact on the user is that SCD queue 2 got
stuck after having removed keys.
The message is the log that was printed is:
Queue 2 stuck for 10000ms
This doesn't seem to fix the higher queues that get stuck
from time to time.

commit 350ab15bb2ffe7103bc6bf6c634f3c5b286eaf2a upstream.
The statically defined I/O memory regions for the i.MX21 on chip
peripherals and the on board I/O peripherals of the i.MX21ADS board
overlap. This results in a kernel crash during startup. This is fixed
by reducing the memory range for the on board I/O peripherals to the
actually required range.

From: Hugh Dickins <[email protected]>
commit 9b15b817f3d62409290fd56fe3cbb076a931bb0a upstream.
Minchan Kim reports that when a system has many swap areas, and tmpfs
swaps out to the ninth or more, shmem_getpage_gfp()'s attempts to read
back the page cannot locate it, and the read fails with -ENOMEM.
Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry(
swp_entry_to_pte()) technique for determining maximum usable swap
offset, without stopping to realize that that actually depends upon the
pte swap encoding shifting swap offset to the higher bits and truncating
it there. Whereas our radix_tree swap encoding leaves offset in the
lower bits: it's swap "type" (that is, index of swap area) that was
truncated.
Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the
broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header().
This does not reduce the usable size of a swap area any further, it
leaves it as claimed when making the original commit: no change from 3.0
on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB
per swapfile on i386 with PAE. It's not a change I would have risked
five years ago, but with x86_64 supported for ten years, I believe it's
appropriate now.
Hmm, and what if some architecture implements its swap pte with offset
encoded below type? That would equally break the maximum usable swap
offset check. Happily, they all follow the same tradition of encoding
offset above type, but I'll prepare a check on that for next.

commit 7c8d51848a88aafdb68f42b6b650c83485ea2f84 upstream.
The 32 bit variant of cbc(aes) decrypt is using instructions requiring
128 bit aligned memory locations but fails to ensure this constraint in
the code. Fix this by loading the data into intermediate registers with
load unaligned instructions.
This fixes reported general protection faults related to aesni.

From: AnilKumar Ch <[email protected]>
commit 148c87c89e1a8863d3d965179f3ab1a06490569e upstream.
This patch fixes an interrupt thrash issue with c_can driver.
In c_can_isr() function interrupts are disabled and enabled only in
c_can_poll() function. c_can_isr() & c_can_poll() both read the
irqstatus flag. However, irqstatus is always read as 0 in c_can_poll()
because all C_CAN interrupts are disabled in c_can_isr(). This causes
all interrupts to be re-enabled in c_can_poll() which in turn causes
another interrupt since the event is not really handled. This keeps
happening causing a flood of interrupts.
To fix this, read the irqstatus register in isr and use the same cached
value in the poll function.

From: AnilKumar Ch <[email protected]>
commit f461f27a4436dbe691908fe08b867ef888848cc3 upstream.
Fix the issue of C_CAN interrupts getting disabled forever when canconfig
utility is used multiple times. According to NAPI usage we disable all
the hardware interrupts in ISR and re-enable them in poll(). Current
implementation calls napi_enable() after hardware interrupts are enabled.
If we get any interrupts between these two steps then we do not process
those interrupts because napi is not enabled. Mostly these interrupts
come because of STATUS is not 0x7 or ERROR interrupts. If napi_enable()
happens before HW interrupts enabled then c_can_poll() function will be
called eventual re-enabling.
This patch moves the napi_enable() call before interrupts enabled.

From: Johannes Berg <[email protected]>
commit 71ecfa1893034eeb1c93e02e22ee2ad26d080858 upstream.
When any interface goes down, it could be the one that we
were doing a remain-on-channel with. We therefore need to
cancel the remain-on-channel and flush the related work
structs so they don't run after the interface has been
removed or even destroyed.
It's also possible in this case that an off-channel SKB
was never transmitted, so free it if this is the case.
Note that this can also happen if the driver finishes
the off-channel period without ever starting it.

On high CPU load the accumulating values in the running_avg_cap
register are very low (below 10), so averaging them too early leads
to unnecessary poor output resolution. Since we pretend to output
micro-Watt we better keep all the bits we have as long as possible.

From: AnilKumar Ch <[email protected]>
commit 617caccebe451716df21c069b079d5936ed7b0f3 upstream.
This patch fixes an issue with transmit routine, which causes
"can_put_echo_skb: BUG! echo_skb is occupied!" message when
using "cansequence -p" on D_CAN controller.
In c_can driver, while transmitting packets tx_echo flag holds
the no of can frames put for transmission into the hardware.
As the comment above c_can_do_tx() indicates, if we find any packet
which is not transmitted then we should stop looking for more.
In the current implementation this is not taken care of causing the
said message.
Also, fix the condition used to find if the packet is transmitted
or not. Current code skips the first tx message object and ends up
checking one extra invalid object.
While at it, fix the comment on top of c_can_do_tx() to use the
terminology "packet" instead of "package" since it is more
standard.

From: Peter Korsgaard <[email protected]>
commit 121daad8fd1dce63076fa55aaedd5dc3f981b334 upstream.
Data valid gets cleared by reading the ISR (status register) and NOT from
reading ODATA (data register). A new data word can become available between
checking ISR and reading ODATA, causing us to reuse the same data word next
time atmel_trng_read() gets called, if that happens before the following
data word is ready.
With this fixed, rngtest no longer complains of 'Continous run' errors.

3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Steffen Rumler <[email protected]>
commit 3c75296562f43e6fbc6cddd3de948a7b3e4e9bcf upstream.
This fixes a problem which can causes kernel oopses while loading
a kernel module.
According to the PowerPC EABI specification, GPR r11 is assigned
the dedicated function to point to the previous stack frame.
In the powerpc-specific kernel module loader, do_plt_call()
(in arch/powerpc/kernel/module_32.c), GPR r11 is also used
to generate trampoline code.
This combination crashes the kernel, in the case where the compiler
chooses to use a helper function for saving GPRs on entry, and the
module loader has placed the .init.text section far away from the
.text section, meaning that it has to generate a trampoline for
functions in the .init.text section to call the GPR save helper.
Because the trampoline trashes r11, references to the stack frame
using r11 can cause an oops.
The fix just uses GPR r12 instead of GPR r11 for generating the
trampoline code. According to the statements from Freescale, this is
safe from an EABI perspective.
I've tested the fix for kernel 2.6.33 on MPC8541.

commit 463454b5dbd8dbab6e2fc6c557329e5b811b9c32 upstream.
If a given interface combination doesn't contain
a required interface type then we missed checking
that and erroneously allowed it even though iface
type wasn't there at all. Add a check that makes
sure that all interface types are accounted for.

commit a2c658505bf5c75516ee0a79287223e86a2474af upstream.
When CONFIG_DEBUG_PREEMPT is enabled, bug is observed in the smp_processor_id().
This is because smp_processor_id() is not called in preempt safe condition.
To fix this issue, use raw_smp_processor_id instead of smp_processor_id.

commit bfd37bb5f681961e255fd2f346c20fdae2ef3f27 upstream.
Volume updates may not be acted upon if there is no clock applied when
the volume update is written. Ensure this doesn't happen by writing out
registers with volume updates after we enable each of the clocks.
There are more registers updated than before as previously we were
relying on wm_hubs to set those for controls it manages.

From: Borislav Petkov <[email protected]>
commit f227d4306cf30e1d5b6f231e8ef9006c34f3d186 upstream.
Currently, the APIC LVT interrupt for error thresholding is implicitly
enabled. However, there are models in the F15h range which do not enable
it. Make the code machinery which sets up the APIC interrupt support
an optional setting and add an ->interrupt_capable member to the bank
representation mirroring that capability and enable the interrupt offset
programming only if it is true.
Simplify code and fixup comment style while at it.
This patch is for stable kernels v3.0 to v3.2.

From: Shawn Guo <[email protected]>
commit 602bf40971d7f9a1ec0b7ba2b7e6427849828651 upstream.
There is a system hang issue on imx6q which can easily be seen with
running a cpu hotplug stress testing (hotplug secondary cores from
user space via sysfs interface for thousands iterations).
It turns out that the issue is caused by coherency of the cpu that
is being shut down. When shutting down a cpu, we need to have the
cpu exit coherency to prevent it from receiving cache, TLB, or BTB
maintenance operations broadcast by other CPUs in the cluster.
Copy cpu_enter_lowpower() and cpu_leave_lowpower() from mach-vexpress
to have coherency properly handled in platform_cpu_die(), thus fix
the issue.

From: Trond Myklebust <[email protected]>
commit 2d0dbc6ae8a5194aaecb9cfffb9053f38fce8b86 upstream.
While nfs4_do_open() expects the fmode argument to be restricted to
combinations of FMODE_READ and FMODE_WRITE, both nfs4_atomic_open()
and nfs4_proc_create will pass the nfs_open_context->mode,
which contains the full fmode_t.
This patch ensures that nfs4_do_open strips the other fmode_t bits,
fixing a problem in which the nfs4_do_open call would result in an
unnecessary delegation return.

My patch
iwlwifi: use correct released ucode version
did not correctly report supported firmware
for the 6035 device. This patch fixes it. The
minimum supported firmware version for 6035
is v6.
Also correct the minimum supported firmware
version for the 6000g2 series of devices.

commit fec67b45bf045582c3172101970090d640cd56d9 upstream.
[v2: Editorial changes suggested by Sergei Shtylyov]
These modems use the Qualcomm MSM Interface (QMI) protocol for
management of their CDC ECM like wwan interface. This driver
is perfect for exporting the protocol to userspace.
The created character device will be indistinguishable from a
common AT command based Device Management interface, so
userspace applications must do some intelligent matching
on the USB device.

From: Andreas Herrmann <[email protected]>
BIOS will switch off the corresponding feature flag on family
15h models 10h-1fh non-desktop CPUs.
The topology extension CPUID leafs are required to detect which
cores belong to the same compute unit. (thread siblings mask is
set accordingly and also correct information about L1i and L2
cache sharing depends on this).
W/o this patch we wouldn't see which cores belong to the same
compute unit and also cache sharing information for L1i and L2
would be incorrect on such systems.

From: Dimitri Sivanich <[email protected]>
commit a841f8cef4bb124f0f5563314d0beaf2e1249d72 upstream.
It does not get processed because sched_domain_level_max is 0 at the
time that setup_relax_domain_level() is run.
Simply accept the value as it is, as we don't know the value of
sched_domain_level_max until sched domain construction is completed.
Fix sched_relax_domain_level in cpuset. The build_sched_domain() routine calls
the set_domain_attribute() routine prior to setting the sd->level, however,
the set_domain_attribute() routine relies on the sd->level to decide whether
idle load balancing will be off/on.

From: Andre Przywara <[email protected]>
commit 5e626254206a709c6e937f3dda69bf26c7344f6f upstream.
Xen PV kernels allow access to the APERF/MPERF registers to read the
effective frequency. Access to the MSRs is however redirected to the
currently scheduled physical CPU, making consecutive read and
compares unreliable. In addition each rdmsr traps into the hypervisor.
So to avoid bogus readouts and expensive traps, disable the kernel
internal feature flag for APERF/MPERF if running under Xen.
This will
a) remove the aperfmperf flag from /proc/cpuinfo
b) not mislead the power scheduler (arch/x86/kernel/cpu/sched.c) to
use the feature to improve scheduling (by default disabled)
c) not mislead the cpufreq driver to use the MSRs
This does not cover userland programs which access the MSRs via the
device file interface, but this will be addressed separately.

A few machines with ALC861 & co are reported not to work properly with
the auto-mute feature in software. The auto-mute feature is implemented
in the hardware level, and the jack-detection never works with them.
Also, rename the fixup index as ALC861_FIXUP_* to follow the standard.

commit 45c72cd73c788dd18c8113d4a404d6b4a01decf1 upstream.
Now we store attr->ino at inode->i_ino, return attr->ino at the
first time and then return inode->i_ino if the attribute timeout
isn't expired. That's wrong on 32 bit platforms because attr->ino
is 64 bit and inode->i_ino is 32 bit in this case.
Fix this by saving 64 bit ino in fuse_inode structure and returning
it every time we call getattr. Also squash attr->ino into inode->i_ino
explicitly.

commit 954c3f8a5f1b7716be9eee978b3bc85bae92d7c8 upstream.
We need to make sure that the USB serial driver we find
matches the USB driver whose probe we are currently
executing. Otherwise we will end up with USB serial
devices bound to the correct serial driver but wrong
USB driver.
An example of such cross-probing, where the usbserial_generic
USB driver has found the sierra serial driver:

So we end up with a mismatch between the USB driver and the
USB serial driver. The reason for the above is simple: The
USB driver probe will succeed if *any* registered serial
driver matches, and will use that serial driver for all
serial driver functions.
This makes ref counting go wrong. We count the USB driver
as used, but not the USB serial driver. This may result
in Oops'es as demonstrated by Johan Hovold <[email protected]>:

Fix by only evaluating serial drivers pointing back to the
USB driver we are currently probing. This still allows two
or more drivers to match the same device, running their
serial driver probes to sort out which one to use.

commit d5d2d2eea84b0d8450b082edbc3dbde41fb8bfd8 upstream.
The SGI Altix UV2 BAU (Broadcast Assist Unit) as used for
tlb-shootdown (selective broadcast mode) always uses UV2
broadcast descriptor format. There is no need to clear the
'legacy' (UV1) mode, because the hardware always uses UV2 mode
for selective broadcast.
But the BIOS uses general broadcast and legacy mode, and the
hardware pays attention to the legacy mode bit for general
broadcast. So the kernel must not clear that mode bit.

From: Alan Stern <[email protected]>
commit c2fb8a3fa25513de8fedb38509b1f15a5bbee47b upstream.
This patch (as1558) fixes a problem affecting several ASUS computers:
The machine crashes or corrupts memory when going into suspend if the
ehci-hcd driver is bound to any controllers. Users have been forced
to unbind or unload ehci-hcd before putting their systems to sleep.
After extensive testing, it was determined that the machines don't
like going into suspend when any EHCI controllers are in the PCI D3
power state. Presumably this is a firmware bug, but there's nothing
we can do about it except to avoid putting the controllers in D3
during system sleep.
The patch adds a new flag to indicate whether the problem is present,
and avoids changing the controller's power state if the flag is set.
Runtime suspend is unaffected; this matters only for system suspend.
However as a side effect, the controller will not respond to remote
wakeup requests while the system is asleep. Hence USB wakeup is not
functional -- but of course, this is already true in the current state
of affairs.
A similar patch has already been applied as commit
151b61284776be2d6f02d48c23c3625678960b97 (USB: EHCI: fix crash during
suspend on ASUS computers). The patch supersedes that one and reverts
it. There are two differences:
The old patch added the flag at the USB level; this patch
adds it at the PCI level.
The old patch applied to all chipsets with the same vendor,
subsystem vendor, and product IDs; this patch makes an
exception for a known-good system (based on DMI information).

From: Daniel Mack <[email protected]>
commit b3a3dd074f7053ef824ad077e5331b52220ceba1 upstream.
TEAC's UD-H01 (and probably other devices) have a gap in the interface
number allocation of their descriptors:
Configuration Descriptor:
bLength 9
bDescriptorType 2
wTotalLength 220
bNumInterfaces 3
[...]
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 0
bAlternateSetting 0
[...]
Interface Association:
bLength 8
bDescriptorType 11
bFirstInterface 2
bInterfaceCount 2
bFunctionClass 1 Audio
bFunctionSubClass 0
bFunctionProtocol 32
iFunction 4
Interface Descriptor:
bLength 9
bDescriptorType 4
bInterfaceNumber 2
bAlternateSetting 0
[...]
Once a configuration is selected, usb_set_configuration() walks the
known interfaces of a given configuration and calls find_iad() on
each of them to set the interface association pointer the interface
is included in.
The problem here is that the loop variable is taken for the interface
number in the comparison logic that gathers the association. Which is
fine as long as the descriptors are sane.
In the case above, however, the logic gets out of sync and the
interface association fields of all interfaces beyond the interface
number gap are wrong.
Fix this by passing the interface's bInterfaceNumber to find_iad()
instead.

From: Roland Dreier <[email protected]>
commit 59e4f541baf728dbb426949bfa9f6862387ffd0e upstream.
The error paths in target_emulate_set_target_port_groups() are all
essentially "rc = -EINVAL; goto out;" but the code at "out:" ignores
rc and always returns success. This means that even if eg explicit
ALUA is turned off, the initiator will always see a good SCSI status
for SET TARGET PORT GROUPS.
Fix this by returning rc as is intended. It appears this bug was
added by the following patch:

commit 42ca7da1c2363dbef4ba1b6917c4c02274b6a5e2 upstream.
Later firmwares for this device now have proper subclass and
protocol info so we can identify it nicely without needing to use
the blacklist. I'm not removing the old 0xff matching as there
may be devices in the field that still need that.

commit afff07e61a5243e14ee3f0a272a0380cd744a8a3 upstream.
This device gives a bogus answer to get_capacity(16):
[ 8628.278614] scsi 8:0:0:0: Direct-Access USB 2.0 USB Flash Drive 1100 PQ: 0 ANSI: 4

So set the quirk flag to avoid using get_capacity(16) with it:
[11731.386014] usb-storage 2-1.6:1.0: Quirks match for vid 090c pid 1000: 80000

PS3 EHCI HC errata fix 244. The SCC EHCI HC will not correctly perform QH
reads that occur near or span a micro-frame boundry. This is due to a problem
in the Nak Count Reload Control logic (EHCI Specification 1.0 Section 4.9.1).
The work-around for this problem is for the HC driver to set I=1 (inactive) for
QHs with H=1 (list head).

------------------
From: Takashi Iwai <[email protected]>
commit 32f1d2c536d0c26c5814cb0e6a0606c42d02fac1 upstream.
This patch fixes a few issues introduced in the recent fix
[f8a9e72d: USB: fix resource leak in xhci power loss path]
- The endpoints listed in bw table are just links and each entry is an
array member of dev->eps[]. But the commit above adds a kfree() call
to these instances, and thus it results in memory corruption.
- It clears only the first entry of rh_bw[], but there can be multiple
ports.
- It'd be safer to clear the list_head of ep as well, not only
removing from the list, as it's checked in

From: Otto Meta <[email protected]>
commit 6c4707f3f8c44ec18282e1c014c80e1c257042f9 upstream.
Currently CDC-ACM devices stay throttled when their TTY is closed while
throttled, stalling further communication attempts after the next open.
Unthrottling during open/activate got lost starting with kernel
3.0.0 and this patch reintroduces it.

3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andiry Xu <[email protected]>
commit 622eb783fe6ff4c1baa47db16c3a5db97f9e6e50 upstream.
When system software decides to power down the xHC with the intent of
resuming operation at a later time, it will ask xHC to save the internal
state and restore it when resume to correctly recover from a power event.
Two bits are used to enable this operation: Save State and Restore State.
xHCI spec 4.23.2 says software should "Set the Controller Save/Restore
State flag in the USBCMD register and wait for the Save/Restore State
Status flag in the USBSTS register to transition to '0'". However, it does
not define how long software should wait for the SSS/RSS bit to transition
to 0.
Currently the timeout is set to 1ms. There is bug report
(https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1002697)
indicates that the timeout is too short for ASMedia ASM1042 host controller
to save/restore the state successfully. Increase the timeout to 10ms helps to
resolve the issue.
This patch should be backported to stable kernels as old as 2.6.37, that
contain the commit 5535b1d5f8885695c6ded783c692e3c0d0eda8ca "USB: xHCI:

From: Takashi Iwai <[email protected]>
commit 46ed8f00d8982e49f8fe2c1a9cea192f640cb3ba upstream.
xhci_free_tt_info() may access the invalid memory when it removes the
last entry but the list is not empty. Then tt_next reaches to the
list head but it still tries to check the tt_info of that entry.
This patch fixes the bug and cleans up the messy code by rewriting
with a simple list_for_each_entry_safe().
This patch should be backported to kernels as old as 3.2, that contain
the commit 839c817ce67178ca3c7c7ad534c571bba1e69ebe "xhci: Store

From: Daniel Vetter <[email protected]>
commit b7884eb45ec98c0d34c7f49005ae9d4b4b4e38f6 upstream.
Empirical evidence suggests that we need to: On at least one ivb
machine when running the hangman i-g-t test, the rings don't properly
initialize properly - the RING_START registers seems to be stuck at
all zeros.
Holding forcewake around this register init sequences makes chip reset
reliable again. Note that this is not the first such issue:
commit f01db988ef6f6c70a6cc36ee71e4a98a68901229
Author: Sean Paul <[email protected]>
Date: Fri Mar 16 12:43:22 2012 -0400
drm/i915: Add wait_for in init_ring_common
added delay loops to make RING_START and RING_CTL initialization
reliable on the blt ring at boot-up. So I guess it won't hurt if we do
this unconditionally for all force_wake needing gpus.
To avoid copy&pasting of the HAS_FORCE_WAKE check I've added a new
intel_info bit for that.
v2: Fixup missing commas in static struct and properly handling the
error case in init_ring_common, both noticed by Jani Nikula.

This interface is half of a control+data interface set being handled by
the cdc-wdm and qmi_wwan drivers in cooperation. The qmi_wwan driver
was first included in 3.4.
Adding only half of the set to cdc-wdm in older stable versions does not
make much sense. I believe this patch should only be applied to 3.4.x
and later. Sorry for not thinking about this earlier and making it
clear in the patch submission.

OK, will drop them both.

Time is nature's way of making sure that everything doesn't happen at once.
Hi,
I'm not sure if this is needed with 3.2, it is needed with 3.4 because
recently the usb-storage driver was changed to report the supported
scsi level as reported by the device, rather then always report a
scsi level of 2. This change causes sd.c to try READ_CAPACITY(16)
first, which foobars up not only this one device, but as it turns
out a lot of others too, so we're working on another fix
(and I believe that 3.2 is unaffected).
With that said, this patch certainly cannot hurt in any way...
Regards,
Hans

Hi,
I wrote the original bug report for the Feiya QDI U2 DISK (bug 43265)
and can confirm that the bug was introduced with kernel 3.4.
3.2 and 3.3 are unaffected.
regards,
Simon

Shouldn't this have been "goto err_unpin;"?
It's not a problem in the backport for 3.2, same code is in the original
patch, just noticed it seems a problem while looking at it; but by what
changelog says the default case is said to not trigger in "practice"
(catch programming error), so I think it doesn't pose a real issue in
practice.

You are right, it should be err_unpin. I sent a patch rectifying this.
In practice, this should not happen, but still, better be safe than
sorry. Thanks for catching that!

So should I drop this until the second patch is upstream?

Nah, just merge it. It covers a truly impossible situation, and I've
decided to not push Eugeni's fixup through -fixes because if that.
Still, thanks for catching this.

I don't think there is a need. It is nearly impossible to hit this
situation, and if it happens the machine will be quite broken in a way
this patch won't help recovering it anyway.
So you could merge the original patch as is - it fixes some real
issues on Ivy Bridge which are much more likely to happen.
