d030260ad3 perf tools: Fix perf_event.h header usage
This patch fixes the usage of the perf_event.h header file
between command modules and the supporting code in util.

It is necessary to ensure that ALL files use the SAME
perf_event.h header from the kernel source tree.

There were a couple of #include <linux/perf_event.h> mixed
with #include "../../perf_event.h".

This caused issues on some distros because of mismatch
in the layout of struct perf_event_attr. That eventually
led perf stat to segfault.

454a3bbe9b perf test: Clarify some error reports in the open syscall test
Rebooted my devel machine, first thing I ran was perf test, that expects

Also add missing newlines and add more informative message when
sys_perf_event_open fails.

a7862aa90f [media] cx25821: Fix compilation breakage due to BKL dependency
drivers/staging/cx25821/cx25821-video.c: In function ‘video_open’:
drivers/staging/cx25821/cx25821-video.c:817:8: error: implicit declaration of function ‘lock_kernel’
drivers/staging/cx25821/cx25821-video.c:834:9: error: implicit declaration of function ‘unlock_kernel’

This patch just adds a header with BKL function. It should be enough
to avoid compilation breakage, but, as BKL will be removed, we need
to properly fix it on a latter patch.

554ec06398 x86: Avoid calling arch_trigger_all_cpu_backtrace() at the same time
The spin_lock_debug/rcu_cpu_stall detector uses
trigger_all_cpu_backtrace() to dump cpu backtrace.
Therefore it is possible that trigger_all_cpu_backtrace()
could be called at the same time on different CPUs, which
triggers and 'unknown reason NMI' warning. The following case
illustrates the problem:

      CPU1                    CPU2                     ...   CPU N
                       trigger_all_cpu_backtrace()
                       set "backtrace_mask" to cpu mask
                               |
generate NMI interrupts  generate NMI interrupts       ...
    \                          |                               /
     \                         |                              /

The "backtrace_mask" will be cleaned by the first NMI interrupt
at nmi_watchdog_tick(), then the following NMI interrupts
generated by other cpus's arch_trigger_all_cpu_backtrace() will
be taken as unknown reason NMI interrupts.

This patch uses a test_and_set to avoid the problem, and stop
the arch_trigger_all_cpu_backtrace() from calling to avoid
dumping a double cpu backtrace info when there is already a
trigger_all_cpu_backtrace() in progress.

6bf4123760 sched: Change wait_for_completion_*_timeout() to return a signed long
wait_for_completion_*_timeout() can return:

   0: if the wait timed out
 -ve: if the wait was interrupted
 +ve: if the completion was completed.

As they currently return an 'unsigned long', the last two cases
are not easily distinguished which can easily result in buggy
code, as is the case for the recently added
wait_for_completion_interruptible_timeout() call in
net/sunrpc/cache.c

So change them both to return 'long'.  As MAX_SCHEDULE_TIMEOUT
is LONG_MAX, a large +ve return value should never overflow.

cb2ded37fd x86: Fix APIC ID sizing bug on larger systems, clean up MAX_APICS confusion
Found one x2apic pre-enabled system, x2apic_mode suddenly get
corrupted after register some cpus, when compiled
CONFIG_NR_CPUS=255 instead of 512.

It turns out that generic_processor_info() ==> phyid_set(apicid,
phys_cpu_present_map) causes the problem.

phys_cpu_present_map is sized by MAX_APICS bits, and pre-enabled
system some cpus have an apic id > 255.

The variable after phys_cpu_present_map may get corrupted
silently:

 ffffffff828e8420 B phys_cpu_present_map
 ffffffff828e8440 B apic_verbosity
 ffffffff828e8444 B local_apic_timer_c2_ok
 ffffffff828e8448 B disable_apic
 ffffffff828e844c B x2apic_mode
 ffffffff828e8450 B x2apic_disabled
 ffffffff828e8454 B num_processors
 ...

Actually phys_cpu_present_map is referenced via apic id, instead
index. We should use MAX_LOCAL_APIC instead MAX_APICS.

For 64-bit it will be 32768 in all cases. BSS will increase by 4k bytes
on 64-bit:

	text		data		bss		dec		filename
	21696943	4193748		12787712	38678403	vmlinux.before
	21696943	4193748		12791808	38682499	vmlinux.after

No change on 32bit.

Finally we can remove MAX_APCIS that was rather confusing.

24a8fdad35 mac80211: serialize rx path workers
This patch addresses the issue of serialization between
the main rx path and various reorder release timers.

<http://www.spinics.net/lists/linux-wireless/msg57214.html>

It converts the previously local "frames" queue into
a global rx queue [rx_skb_queue]. This way, everyone
(be it the main rx-path or some reorder release timeout)
can add frames to it.

Only one active rx handler worker [ieee80211_rx_handlers]
is needed. All other threads which have lost the race of
"runnning_rx_handler" can now simply "return", knowing that
the thread who had the "edge" will also take care of their
workload.

Event though with the above commit we obtain the configured DTIM period
from the AP rather than always hardcoding it to '1', this seems to cause
problems under the following scenarios:
* Preventing association with broken AP's
* Adds latency in roaming
So its better to always use the safe value of '1' for dtim period

f76b57b47e mac80211: Fix mesh portal communication with other mesh nodes.
Fixed a bug where if a mesh interface has a different MAC address from its bridge
interface, then it would not be able to send data traffic to any other mesh node.
This also adds support for communication between mesh nodes and external bridged
nodes by using a 6 address format if the source is a node within the mesh and the
destination is an external node proxied by a mesh portal.

1c30cc1908 ath9k_hw: fix dma descriptor rx error bit parsing
An Rx DMA descriptor can have multiple error bits set, and some error
bits (e.g. MIC failure) are filtered by the driver based on other criteria.
Remove the 'else' in various error bit checks so that all error information
is properly passed to the driver.

039a07215e ath9k_htc: Fix fast channel change
When returning to the operating channel, a full HW
reset has to be done instead of a fast channel change.
Since sw_scan_complete() is called after the config() call for the
home channel, we end up doing a FCC. Fix this issue by checking
the OFFCHANNEL flag to determine FCC.

The device has to be reset when a FATAL event is received.
Not doing so would leave the card in a non-working state.

ff8f59b5bb ath9k_htc: Handle pending URBs properly
When doing a channel change, the pending URBs have to be killed
properly on calling htc_stop().

This fixes the probe response timeout seen when sending UDP traffic at
a high rate and running background scan at the same time.
