8139cp: revert "set ring address before enabling receiver"
commit b26623dab7eeb1e9f5898c7a49458789dd492f20 upstream.
This patch reverts b01af4579ec41f48e9b9c774e70bd6474ad210db.
The original patch was tested with emulated hardware. Real
hardware chokes.

x86, amd: Disable way access filter on Piledriver CPUs
commit 2bbf0a1427c377350f001fbc6260995334739ad7 upstream.
The Way Access Filter in recent AMD CPUs may hurt the performance of
some workloads, caused by aliasing issues in the L1 cache.
This patch disables it on the affected CPUs.
The issue is similar to that one of last year:
http://lkml.indiana.edu/hypermail/linux/kernel/1107.3/00041.html
This new patch does not replace the old one, we just need another
quirk for newer CPUs.
The performance penalty without the patch depends on the
circumstances, but is a bit less than the last year's 3%.
The workloads affected would be those that access code from the same
physical page under different virtual addresses, so different
processes using the same libraries with ASLR or multiple instances of
PIE-binaries. The code needs to be accessed simultaneously from both
cores of the same compute unit.
More details can be found here:
http://developer.amd.com/Assets/SharedL1InstructionCacheonAMD15hCPU.pdf
CPUs affected are anything with the core known as Piledriver.
That includes the new parts of the AMD A-Series (aka Trinity) and the
just released new CPUs of the FX-Series (aka Vishera).
The model numbering is a bit odd here: FX CPUs have model 2,
A-Series has model 10h, with possible extensions to 1Fh. Hence the
range of model ids.

net: qmi_wwan: add Huawei E173
commit ba695af067f9cadfec84457ac06b44e3fa849b15 upstream.
The Huawei E173 is a QMI/wwan device which normally appear
as 12d1:1436 in Linux. The descriptors displayed in that
mode will be picked up by cdc_ether. But the modem has
another mode with a different device ID and a slightly
different set of descriptors. This is the mode used by
Windows like this:

i7core_edac: fix panic when accessing sysfs files
commit 42709efb3a47524c6252e1bdc85e205f7bc356fb upstream.
The i7core_edac addrmatch_dev and chancounts_dev have sysfs files
associated with them. The sysfs files, however, are coded so that the
parent device is is the mci device. This is incorrect and the mci struct
should be obtained through the addrmatch_dev and chancounts_dev device's
private data field which is populated in i7core_create_sysfs_devices().

Revert "sched, autogroup: Stop going ahead if autogroup is disabled"
commit fd8ef11730f1d03d5d6555aa53126e9e34f52f12 upstream.
This reverts commit 800d4d30c8f20bd728e5741a3b77c4859a613f7c.
Between commits 8323f26ce342 ("sched: Fix race in task_group()") and
800d4d30c8f2 ("sched, autogroup: Stop going ahead if autogroup is
disabled"), autogroup is a wreck.
With both applied, all you have to do to crash a box is disable
autogroup during boot up, then reboot.. boom, NULL pointer dereference
due to commit 800d4d30c8f2 not allowing autogroup to move things, and
commit 8323f26ce342 making that the only way to switch runqueues:

md/raid1{,0}: fix deadlock in bitmap_unplug.
commit 874807a83139abc094f939e93623c5623573d543 upstream.
If the raid1 or raid10 unplug function gets called
from a make_request function (which is very possible) when
there are bios on the current->bio_list list, then it will not
be able to successfully call bitmap_unplug() and it could
need to submit more bios and wait for them to complete.
But they won't complete while current->bio_list is non-empty.
So detect that case and handle the unplugging off to another thread
just like we already do when called from within the scheduler.
RAID1 version of bug was introduced in 3.6, so that part of fix is
suitable for 3.6.y. RAID10 part won't apply.

mac80211: fix remain-on-channel (non-)cancelling
commit 6bdd253f635f7b2ef027d116933a6c9ec148b87f upstream.
Felix Liao reported that when an interface is set DOWN
while another interface is executing a ROC, the warning
in ieee80211_start_next_roc() (about the first item on
the list having started already) triggers.
This is because ieee80211_roc_purge() calls it even if
it never actually changed the list of ROC items. To fix
this, simply remove the function call. If it is needed
then it will be done by the ieee80211_sw_roc_work()
function when the ROC item that is being removed while
active is cleaned up.

x86, fpu: Avoid FPU lazy restore after suspend
commit 644c154186386bb1fa6446bc5e037b9ed098db46 upstream.
When a cpu enters S3 state, the FPU state is lost.
After resuming for S3, if we try to lazy restore the FPU for a process running
on the same CPU, this will result in a corrupted FPU context.
Ensure that "fpu_owner_task" is properly invalided when (re-)initializing a CPU,
so nobody will try to lazy restore a state which doesn't exist in the hardware.
Tested with a 64-bit kernel on a 4-core Ivybridge CPU with eagerfpu=off,
by doing thousands of suspend/resume cycles with 4 processes doing FPU
operations running. Without the patch, a process is killed after a
few hundreds cycles by a SIGFPE.

ARM: Kirkwood: Update PCI-E fixup
commit 1dc831bf53fddcc6443f74a39e72db5bcea4f15d upstream.
- The code relies on rc_pci_fixup being called, which only happens
when CONFIG_PCI_QUIRKS is enabled, so add that to Kconfig. Omitting
this causes a booting failure with a non-obvious cause.
- Update rc_pci_fixup to set the class properly, copying the
more modern style from other places
- Correct the rc_pci_fixup comment

commit 3ea160b3e8f0de8161861995d9901f61192fc0b0 upstream.
- If we stop processing an already-aborted command in
target_execute_cmd(), then we need to complete t_transport_stop_comp
to wake up the the TMR handling thread, or else it will end up
waiting forever.
- If we've a already sent an "aborted" status for a command in
transport_check_aborted_status() then we should bail out of
transport_send_task_abort() to avoid freeing the command twice.

commit 783657a7dc20e5c0efbc9a09a9dd38e238a723da upstream.
When we try to soft-offline a thp tail page, put_page() is called on the
tail page unthinkingly and VM_BUG_ON is triggered in put_compound_page().
This patch splits thp before going into the main body of soft-offlining.

mm: vmscan: fix endless loop in kswapd balancing
commit 60cefed485a02bd99b6299dad70666fe49245da7 upstream.
Kswapd does not in all places have the same criteria for a balanced
zone. Zones are only being reclaimed when their high watermark is
breached, but compaction checks loop over the zonelist again when the
zone does not meet the low watermark plus two times the size of the
allocation. This gets kswapd stuck in an endless loop over a small
zone, like the DMA zone, where the high watermark is smaller than the
compaction requirement.
Add a function, zone_balanced(), that checks the watermark, and, for
higher order allocations, if compaction has enough free memory. Then
use it uniformly to check for balanced zones.
This makes sure that when the compaction watermark is not met, at least
reclaim happens and progress is made - or the zone is declared
unreclaimable at some point and skipped entirely.

mm/vmemmap: fix wrong use of virt_to_page
commit ae64ffcac35de0db628ba9631edf8ff34c5cd7ac upstream.
I enable CONFIG_DEBUG_VIRTUAL and CONFIG_SPARSEMEM_VMEMMAP, when doing
memory hotremove, there is a kernel BUG at arch/x86/mm/physaddr.c:20.
It is caused by free_section_usemap()->virt_to_page(), virt_to_page() is
only used for kernel direct mapping address, but sparse-vmemmap uses
vmemmap address, so it is going wrong here.

commit d356cf5a74afa32b40decca3c9dd88bc3cd63eb5 upstream.
PMU interrupts start at IRQ_DOVE_PMU_START, not IRQ_DOVE_PMU_START + 1.
Fix the condition. (It may have been less likely to occur had the code
been written "if (irq >= IRQ_DOVE_PMU_START" which imho is the easier
to understand notation, and matches the normal way of thinking about
these things.)

Dove: Attempt to fix PMU/RTC interrupts
commit 5d3df935426271016b895aecaa247101b4bfa35e upstream.
Fix the acknowledgement of PMU interrupts on Dove: some Dove hardware
has not been sensibly designed so that interrupts can be handled in a
race free manner. The PMU is one such instance.
The pending (aka 'cause') register is a bunch of RW bits, meaning that
these bits can be both cleared and set by software (confirmed on the
Armada-510 on the cubox.)
Hardware sets the appropriate bit when an interrupt is asserted, and
software is required to clear the bits which are to be processed. If
we write ~(1 << bit), then we end up asserting every other interrupt
except the one we're processing. So, we need to do a read-modify-write
cycle to clear the asserted bit.
However, any interrupts which occur in the middle of this cycle will
also be written back as zero, which will also clear the new interrupts.
The upshot of this is: there is _no_ way to safely clear down interrupts
in this register (and other similarly behaving interrupt pending
registers on this device.) The patch below at least stops us creating
new interrupts.
