commit 629c66a22c21b692b6e58b9c1d8fa56a60ccb52d upstream.
When tests were added to lkdtm that grew the stack frame, the stack
corruption test stopped working. This isolates the test in its own
function, and forces it not to be inlined.

commit 67aa4acbc97f6a55b328e4e2305ef19cbe949d85 upstream.
`comedi_alloc_spriv()` allocates private storage for a comedi subdevice
and sets the `SRF_FREE_SPRIV` flag in the `runflags` member of the
subdevice to allow the private storage to be automatically freed when
the comedi device is being cleaned up. Unfortunately, the flag gets
clobbered by `do_cmd_ioctl()` which calls
`comedi_set_subdevice_runflags()` with a mask value `~0` and only the
`SRF_USER` and `SRF_RUNNING` flags set, all the other SRF flags being
cleared.
Change the calls to `comedi_set_subdevice_runflags()` that currently use
a mask value of `~0` to use a more relevant mask value. For
`do_cmd_ioctl()`, the relevant SRF flags are `SRF_USER`, `SRF_ERROR` and
`SRF_RUNNING`. (At one time, `SRF_RT` would be included in that set of
flags, but it is no longer used.) For `comedi_alloc_spriv()` replace
the call to `comedi_set_subdevice_runflags()` with a simple
OR-assignment to avoid unnecessary use of a spin-lock.

commit 46a51c80216cb891f271ad021f59009f34677499 upstream.
This patch fixes the bug in reset_store caused by accessing NULL pointer.
The bdev gets its value from bdget_disk() which could fail when memory
pressure is severe and hence can return NULL because allocation of
inode in bdget could fail.
Hence, this patch introduces a check for bdev to prevent reference to a
NULL pointer in the later part of the code. It also removes unnecessary
check of bdev for fsync_bdev().

commit 176a88d79d6b5aebabaff16734e8b3107efcaaad upstream.
According to the ACPI spec (5.0, Section 6.3.5), the "Device
insertion in progress (pending)" (0x80) _OST status code is
reserved for the "Insertion Processing" (0x200) source event
which is "a result of an OSPM action". Specifically, it is not
a notification, so that status code should not be used during
notification processing, which unfortunately is done by
acpi_scan_bus_device_check().
For this reason, drop the ACPI_OST_SC_INSERT_IN_PROGRESS _OST
status evaluation from there (it was a mistake to put it in there
in the first place).

commit 2441191a19039002b2c454a261fb45986df15184 upstream.
It is required to do get_device() on the struct acpi_device in
question before passing it to acpi_bus_hot_remove_device() through
acpi_os_hotplug_execute(), because acpi_bus_hot_remove_device()
calls acpi_scan_hot_remove() that does put_device() on that
object.
The ACPI PCI root removal routine, handle_root_bridge_removal(),
doesn't do that, which may lead to premature freeing of the
device object or to executing put_device() on an object that
has been freed already.
Fix this problem by making handle_root_bridge_removal() use
get_device() as appropriate.

commit 2c62333a408f5badd2d2ffd7177f95deeccc5ca4 upstream.
Some firmware doesn't initialize initial backlight level to a proper
value and _BQC will return 0 on first time evaluation. We used to be
able to detect such incorrect value with our code logic, as value 0
normally isn't a valid value in _BCL. But with the introduction of Win8,
firmware begins to fill _BCL with values from 0 to 100, now 0 becomes
a valid value but that value will make user's screen black. This patch
test initial _BQC for value 0, if such a value is returned, do not use
it.

commit 36b15875a7819a2ec4cb5748ff7096ad7bd86cbb upstream.
A bug was introduced by commit b76b51ba0cef ('ACPI / EC: Add more debug
info and trivial code cleanup') that erroneously caused the struct member
to be accessed before acquiring the required lock. This change fixes
it by ensuring the lock acquisition is done first.

commit ea8117478918a4734586d35ff530721b682425be upstream.
Mike reported that commit 7d1a9417 ("x86: Use generic idle loop")
regressed several workloads and caused excessive reschedule
interrupts.
The patch in question failed to notice that the x86 code had an
inverted sense of the polling state versus the new generic code (x86:
default polling, generic: default !polling).
Fix the two prominent x86 mwait based idle drivers and introduce a few
new generic polling helpers (fixing the wrong smp_mb__after_clear_bit
usage).
Also switch the idle routines to using tif_need_resched() which is an
immediate TIF_NEED_RESCHED test as opposed to need_resched which will
end up being slightly different.

commit 5957324045ba2c127c9401fa3ac61ac52e043ca8 upstream.
Hopefully this isn't too late for 3.12.
In commit 7dc19d5aff (convert shrinkers to new count/scan API)
the return value to PURGE_ALL_CACHES was dropped, causing -EPERM
to always be returned.
This patch re-adds the ret assignment, setting it to the the
ashmem_shrink_count(), which is the lru_count.
(Sorry this was missed in the review!)

commit 5d0f801a2ccec3b1fdabc3392c8d99ed0413d216 upstream.
If we handle end of block messages with higher priority than a lost message,
we can run into an endless interrupt loop.
This is reproducable with a am335x processor and "cansequence -r" at 1Mbit.
As soon as we loose a packet we can't escape from an interrupt loop.
This patch fixes the problem by handling lost packets before EOB packets.

commit b4789b8e6be3151a955ade74872822f30e8cd914 upstream.
It appears that driver runs into a problem here if fibsize is too small
because we allocate user_srbcmd with fibsize size only but later we
access it until user_srbcmd->sg.count to copy it over to srbcmd.
It is not correct to test (fibsize < sizeof(*user_srbcmd)) because this
structure already includes one sg element and this is not needed for
commands without data. So, we would recommend to add the following
(instead of test for fibsize == 0).

commit 7ad9684721606efbfb9b347346816e1e6baff8bb upstream.
This patch adds a pci stub driver to hyper-fb. The hyperv framebuffer
driver will bind to the pci device then, so linux kernel and userspace
know there is a proper kernel driver for the device active. lspci shows
this for example:
[root@dhcp231 ~]# lspci -vs8
00:08.0 VGA compatible controller: Microsoft Corporation Hyper-V virtual
VGA (prog-if 00 [VGA controller])
Flags: bus master, fast devsel, latency 0, IRQ 11
Memory at f8000000 (32-bit, non-prefetchable) [size=64M]
Expansion ROM at <unassigned> [disabled]
Kernel driver in use: hyperv_fb
Another effect is that the xorg vesa driver will not attach to the
device and thus the Xorg server will automatically use the fbdev
driver instead.

[ Upstream commit 059dfa6a93b779516321e5112db9d7621b1367ba ]
time_after_eq() only works if the delta is < MAX_ULONG/2.
For a 32bit Dom0, if netfront sends packets at a very low rate, the time
between subsequent calls to tx_credit_exceeded() may exceed MAX_ULONG/2
and the test for timer_after_eq() will be incorrect. Credit will not be
replenished and the guest may become unable to send packets (e.g., if
prior to the long gap, all credit was exhausted).
Use jiffies_64 variant to mitigate this problem for 32bit Dom0.

Pull USB fixes from Greg KH:
"Here is a set of patches that revert all of the changes done to the
pl2303 USB serial driver in the 3.12-rc timeframe, as it turns out
they break some devices that work just fine on 3.11. As it's not a
good idea to break working systems, drop them all and they will be
reworked for future kernel versions such that there is no breakage.
I've also included a MAINTAINERS update for the USB serial subsystem
and a new device id for the ftdi_sio driver as well"

they cause regressions on some versions of the chip. This will all be
revisited for later kernel versions when we can figure out how to handle
