Kuninori Morimoto 504b61630a usb: ch9.h: usb_endpoint_maxp() uses __le16_to_cpu()
The usb/ch9.h will be installed to /usr/include/linux,
and be used from user space.
But le16_to_cpu() is only defined for kernel code.
Without this patch, user space compile will be broken.

Oleg Nesterov 6d08f2c713 proc: make sure mem_open() doesn't pin the target's memory
Once /proc/pid/mem is opened, the memory can't be released until
mem_release() even if its owner exits.

Change mem_open() to do atomic_inc(mm_count) + mmput(), this only
pins mm_struct. Change mem_rw() to do atomic_inc_not_zero(mm_count)
before access_remote_vm(), this verifies that this mm is still alive.

I am not sure what should mem_rw() return if atomic_inc_not_zero()
fails. With this patch it returns zero to match the "mm == NULL" case,
may be it should return -EINVAL like it did before e268337d.

Perhaps it makes sense to add the additional fatal_signal_pending()
check into the main loop, to ensure we do not hold this memory if
the target task was oom-killed.

Emmanuel Grumbach 3d29dd9b5b iwlwifi: don't mess up QoS counters with non-QoS frames
In my AMPDU rework, I rely on the sequence numbers of frames. But
I didn't check that the frame has a valid tid before updating the
tracking counters. As a result, the Tx queues were stalled. People
who hit this bug saw that we simply didn't let any data out.

This bug was introduced in 3.3.

This patch fixes that and checks that the frame is a QoS frame before
looking at its tid and changing the counters.

Luigi Tarenga 7fc4175564 rt2800lib: fix wrong -128dBm when signal is stronger than -12dBm
This patch correct the type of variables containing the rssi
values read from the rxwi.

In function rt2800_agc_to_rssi() 3 variables (rssi0, rssi1, rss2)
defined as int was assigned a 16bit signed values as unsigned.
From a test with a hi-gain antenna I verified that the rxwi
contains signed rssi values in the  range -13/+81 (inclusive)
with 0 as an error condition. In case of negative values a
condition is triggered and the function return -128dBm while
the signal is at its maximum. This patch correct the cast so
negative values are not treated as very high positive values
(ex. -13 does not become 243).

Artem Bityutskiy 7d73101921 mtd: fix merge conflict resolution breakage
This patch fixes merge conflict resolution breakage introduced by merge
d3712b9dfc ("Merge tag 'for-linus' of git://github.com/prasad-joshi/logfs_upstream").

The commit changed 'mtd_can_have_bb()' function and made it always
return zero, which is incorrect.  Instead, we need it to return whether
the underlying flash device can have bad eraseblocks or not.  UBI needs
this information because it affects how it handles the underlying flash.
E.g., if the underlying flash is NOR, it cannot have bad blocks and any
write or erase error is fatal, and all we can do is to switch to R/O
mode.  We do not need to reserve a pool of good eraseblocks for bad
eraseblocks handling, and so on.

This patch also removes 'mtd_can_have_bb()' invocations from Logfs to
ensure correct Logfs behavior.

I've tested that with this patch UBI works on top of NOR and NAND
flashes emulated by mtdram and nandsim correspondingly.

This patch is based on patch from Linus Torvalds.

The value of this register is transferred to the V_COUNTER register at the
beginning of vertical blank. V_COUNTER is the reference for VLINE waits and
goes from VIEWPORT_Y_START to VIEWPORT_Y_START+VIEWPORT_HEIGHT during scanout,
so if VIEWPORT_Y_START is not 0, V_COUNTER actually went backwards at the
beginning of vertical blank, and VLINE waits excluding the whole scanout area
could never finish (possibly only if VIEWPORT_Y_START is larger than the length
of vertical blank in scanlines). Setting DESKTOP_HEIGHT to the framebuffer
height should prevent this for any kind of VLINE wait.

Dmitry Kasatkin f58a08152c lib/digsig: additional sanity checks against badly formated key payload
Added sanity checks for possible wrongly formatted key payload data:
- minimum key payload size
- zero modulus length
- corrected upper key payload boundary.

do_encode_md() and mpi_get_keyid() are not parts of mpi library.
They were used early versions of gnupg and in digsig project,
but they are not used neither here nor there anymore.

David Henningsson 54c2a89f60 ALSA: HDA: Fix duplicated output to more than one codec
This typo caused the wrong codec's nid to be checked for wcaps type.
As a result, sometimes speakers would duplicate the output sent to
HDMI output.

Gleb Natapov 5753785fa9 KVM: do not #GP on perf MSR writes when vPMU is disabled
Return to behaviour perf MSR had before introducing vPMU in case vPMU
is disabled. Some guests access those registers unconditionally and do
not expect it to fail.

Stephan Bärwolf c2226fc9e8 KVM: x86: fix missing checks in syscall emulation
On hosts without this patch, 32bit guests will crash (and 64bit guests
may behave in a wrong way) for example by simply executing following
nasm-demo-application:

    [bits 32]
    global _start
    SECTION .text
    _start: syscall

(I tested it with winxp and linux - both always crashed)

    Disassembly of section .text:

    00000000 <_start>:
       0:   0f 05                   syscall

The reason seems a missing "invalid opcode"-trap (int6) for the
syscall opcode "0f05", which is not available on Intel CPUs
within non-longmodes, as also on some AMD CPUs within legacy-mode.
(depending on CPU vendor, MSR_EFER and cpuid)

Because previous mentioned OSs may not engage corresponding
syscall target-registers (STAR, LSTAR, CSTAR), they remain
NULL and (non trapping) syscalls are leading to multiple
faults and finally crashs.

Depending on the architecture (AMD or Intel) pretended by
guests, various checks according to vendor's documentation
are implemented to overcome the current issue and behave
like the CPUs physical counterparts.
