Zhanghaoyu (A) 764bcbc5a6 KVM: x86: remove vcpu's CPL check in host-invoked XCR set
__kvm_set_xcr function does the CPL check when set xcr. __kvm_set_xcr is
called in two flows, one is invoked by guest, call stack shown as below,

  handle_xsetbv(or xsetbv_interception)
    kvm_set_xcr
      __kvm_set_xcr

the other one is invoked by host, for example during system reset:

  kvm_arch_vcpu_ioctl
    kvm_vcpu_ioctl_x86_set_xcrs
      __kvm_set_xcr

The former does need the CPL check, but the latter does not.

Fernando Luis Vazquez Cao 788dfcacac vlan: restore ethtool ABI to control VLAN hardware acceleration
As part of the push to add 802.1ad server provider tagging support to the
kernel the VLAN features flags were renamed. Unfortunately the kernel name
for the VLAN hardware acceleration features that the kernel shows user space
was included in the rename, which broke ethtool (txvlan and rxvlan options
do not work). This patch restores the original names, i.e. the original ABI.
If we wanted to make clear to users that we are refering to CTAGs we can
always change ethtool's short_name and long_name for these features (for
example something along the lines of txvlan -> txvlan-ctag, tx-vlan-offload ->
tx-vlan-ctag-offload).

Maxim Patlasov 14c14414d1 fuse: hold i_mutex in fuse_file_fallocate()
Changing size of a file on server and local update (fuse_write_update_size)
should be always protected by inode->i_mutex. Otherwise a race like this is
possible:

1. Process 'A' calls fallocate(2) to extend file (~FALLOC_FL_KEEP_SIZE).
fuse_file_fallocate() sends FUSE_FALLOCATE request to the server.
2. Process 'B' calls ftruncate(2) shrinking the file. fuse_do_setattr()
sends shrinking FUSE_SETATTR request to the server and updates local i_size
by i_size_write(inode, outarg.attr.size).
3. Process 'A' resumes execution of fuse_file_fallocate() and calls
fuse_write_update_size(inode, offset + length). But 'offset + length' was
obsoleted by ftruncate from previous step.

Changed in v2 (thanks Brian and Anand for suggestions):
 - made relation between mutex_lock() and fuse_set_nowrite(inode) more
   explicit and clear.
 - updated patch description to use ftruncate(2) in example

David S. Miller c5b248dd05 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless
John W. Linville says:

====================
This will probably be the last batch of wireless fixes intended
for 3.10.  Many of these are one- or two-liners, and a couple of
others are mostly relocating existing code to avoid races or to
limit the code to effecting specific hardware, etc.

The mac80211 fixes have a couple of exceptions to the above.
Regarding those, Johannes says:

"Following davem's complaint about my patch, here's a new pull request
w/o the patch he was complaining about, but instead with the const
fix rolled into the fix.

I have a fix for radar detection, one for rate control and a workaround
for broken HT APs which is a regression fix because we didn't rely
on them to be correct before."

Johannes also sends some iwlwifi fixes:

"I picked up Nikolay's patch for the chain noise calibration bug
that seems to have been there forever, a fix from Emmanuel for
setting TX flags on BAR frames and a fix of my own to avoid printing
request_module() errors if the kernel isn't even modular. We also
have our own version of Stanislaw's fix for rate control."

Along with those...

Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU
value is set to too small of a value.

Arend van Spriel sends a revised brcmsmac bug that fixes a regression
caused by a bad return value in an earlier patch.  He also sends a
brcmfmac fix to avoid an oops when loading the driver at boot.

Daniel Drake fixes a race condition in btmrvl that causes hangs on
suspend for OLPC hardware.

Johan Hedberg adds a check to avoid sending a
HCI_Delete_Stored_Link_Key command to devices that don't support them,
avoiding some scary looking log spam.

Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates
higher than 1Mb/s on older wireless networks.  He also sends an rt2x00
fix to reinstate older tx power handling behavior for some devices
that didn't work well with the current code.

Johannes Berg ab69bde6b2 alx: add a simple AR816x/AR817x device driver
This is a very simple driver, based on the original vendor
driver that Qualcomm/Atheros published/submitted previously,
but reworked to make the code saner. However, it also lost
a number of features (TSO/GSO, VLAN acceleration and multi-
queue support) in the process, as well as debugging support
features I didn't have any use for. The only thing I left
is checksum offload.

More features can obviously be added, but this seemed like
a good start for having a driver in mainline at all.

Johannes Stezenbach has verified that the driver works on
AR8161, I have a AR8171 myself. The E2200 device ID I found
on github in somebody's repository.

Stephen Warren 19ab428f4b ARM: 7759/1: decouple CPU offlining from reboot/shutdown
Add comments to machine_shutdown()/halt()/power_off()/restart() that
describe their purpose and/or requirements re: CPUs being active/not.

In machine_shutdown(), replace the call to smp_send_stop() with a call to
disable_nonboot_cpus(). This completely disables all but one CPU, thus
satisfying the requirement that only a single CPU be active for kexec.
Adjust Kconfig dependencies for this change.

In machine_halt()/power_off()/restart(), call smp_send_stop() directly,
rather than via machine_shutdown(); these functions don't need to
completely de-activate all CPUs using hotplug, but rather just quiesce
them.

Remove smp_kill_cpus(), and its call from smp_send_stop().
smp_kill_cpus() was indirectly calling smp_ops.cpu_kill() without calling
smp_ops.cpu_die() on the target CPUs first. At least some implementations
of smp_ops had issues with this; it caused cpu_kill() to hang on Tegra,
for example. Since smp_send_stop() is only used for shutdown, halt, and
power-off, there is no need to attempt any kind of CPU hotplug here.

Adjust Kconfig to reflect that machine_shutdown() (and hence kexec)
relies upon disable_nonboot_cpus(). However, this alone doesn't guarantee
that hotplug will work, or even that hotplug is implemented for a
particular piece of HW that a multi-platform zImage runs on. Hence, add
error-checking to machine_kexec() to determine whether it did work.

the behavior when deallocating VT 1.  Previously if trying to
deallocate VT1 and it is busy, we would return EBUSY.  The commit
changed this to return 0 (success).

This commit restores the old behavior.

Commit f8b63c1 made flush_kernel_dcache_page a no-op assuming that
the pages it needs to handle are kernel mapped only.  However, for
example when doing direct I/O, pages with user space mappings may
occur.

Thus, continue to do lazy flushing if there are no user space
mappings.  Otherwise, flush the kernel cache lines directly.

Clemens Ladisch 342cda2934 ALSA: usb-audio: work around Android accessory firmware bug
When the Android firmware enables the audio interfaces in accessory
mode, it always declares in the control interface's baInterfaceNr array
that interfaces 0 and 1 belong to the audio function.  However, the
accessory interface itself, if also enabled, already is at index 0 and
shifts the actual audio interface numbers to 1 and 2, which prevents the
PCM streaming interface from being seen by the host driver.

To get the PCM interface interface to work, detect when the descriptors
point to the (for this driver useless) accessory interface, and redirect
to the correct one.

Chris Wilson 19b2dbde57 drm/i915: Restore fences after resume and GPU resets
Stéphane Marchesin found that fences for pinned objects (i.e. the
scanout) were not being restored upon resume, leading to corruption on
the display and reference counting issues. This is due to a bug in

commit 312817a39f [2.6.38]
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date:   Mon Nov 22 11:50:11 2010 +0000

    drm/i915: Only save and restore fences for UMS

that zapped the pinned fences even though they were in use.
Fortuitously, whilst we forced a VT switch during suspend and resume,
no fences were ever pinned at the time. However, we now can do
switchless S3 transitions and so the old bug finally surfaces.

David Daney f21afc25f9 smp.h: Use local_irq_{save,restore}() in !SMP version of on_each_cpu().
Thanks to commit f91eb62f71 ("init: scream bloody murder if interrupts
are enabled too early"), "bloody murder" is now being screamed.

With a MIPS OCTEON config, we use on_each_cpu() in our
irq_chip.irq_bus_sync_unlock() function.  This gets called in early as a
result of the time_init() call.  Because the !SMP version of
on_each_cpu() unconditionally enables irqs, we get:

    WARNING: at init/main.c:560 start_kernel+0x250/0x410()
    Interrupts were enabled early
    CPU: 0 PID: 0 Comm: swapper Not tainted 3.10.0-rc5-Cavium-Octeon+ #801
    Call Trace:
      show_stack+0x68/0x80
      warn_slowpath_common+0x78/0xb0
      warn_slowpath_fmt+0x38/0x48
      start_kernel+0x250/0x410

Suggested fix: Do what we already do in the SMP version of
on_each_cpu(), and use local_irq_save/local_irq_restore.  Because we
need a flags variable, make it a static inline to avoid name space
issues.

[ Change from v1: Convert on_each_cpu to a static inline function, add
  #include <linux/irqflags.h> to avoid build breakage on some files.

  on_each_cpu_mask() and on_each_cpu_cond() suffer the same problem as
  on_each_cpu(), but they are not causing !SMP bugs for me, so I will
  defer changing them to a less urgent patch. ]

When replaying interrupts (as a result of the interrupt occurring
while soft-disabled), in the case of the decrementer, we are exclusively
testing for a pending timer target. However we also use decrementer
interrupts to trigger the new "irq_work", which in this case would
be missed.

This change the logic to force a replay in both cases of a timer
boundary reached and a decrementer interrupt having actually occurred
while disabled. The former test is still useful to catch cases where
a CPU having been hard-disabled for a long time completely misses the
interrupt due to a decrementer rollover.

Paul Mackerras bf593907f7 powerpc: Fix emulation of illegal instructions on PowerNV platform
Normally, the kernel emulates a few instructions that are unimplemented
on some processors (e.g. the old dcba instruction), or privileged (e.g.
mfpvr).  The emulation of unimplemented instructions is currently not
working on the PowerNV platform.  The reason is that on these machines,
unimplemented and illegal instructions cause a hypervisor emulation
assist interrupt, rather than a program interrupt as on older CPUs.
Our vector for the emulation assist interrupt just calls
program_check_exception() directly, without setting the bit in SRR1
that indicates an illegal instruction interrupt.  This fixes it by
making the emulation assist interrupt set that bit before calling
program_check_interrupt().  With this, old programs that use no-longer
implemented instructions such as dcba now work again.
