Amir Vadai c8c40b7f32 net/mlx4_en: loopbacked packets are dropped when SMAC=DMAC
Should NOT check SMAC=DMAC when:
1. loopback is turned on
2. validate_loopback is true.

Fixed it accordingly.

Hiroaki SHIMODA 696ecdc106 net_sched: gact: Fix potential panic in tcf_gact().
gact_rand array is accessed by gact->tcfg_ptype whose value
is assumed to less than MAX_RAND, but any range checks are
not performed.

So add a check in tcf_gact_init(). And in tcf_gact(), we can
reduce a branch.

Artem Bityutskiy 34e5053fbe Documentation: get rid of write_super
The '->write_super' superblock method is gone, and this patch removes all the
references to 'write_super' from various pieces of the kernel documentation.

Artem Bityutskiy f0cd2dbb6c vfs: kill write_super and sync_supers
Finally we can kill the 'sync_supers' kernel thread along with the
'->write_super()' superblock operation because all the users are gone.
Now every file-system is supposed to self-manage own superblock and
its dirty state.

The nice thing about killing this thread is that it improves power management.
Indeed, 'sync_supers' is a source of monotonic system wake-ups - it woke up
every 5 seconds no matter what - even if there were no dirty superblocks and
even if there were no file-systems using this service (e.g., btrfs and
journalled ext4 do not need it). So it was wasting power most of the time. And
because the thread was in the core of the kernel, all systems had to have it.
So I am quite happy to make it go away.

Interestingly, this thread is a left-over from the pdflush kernel thread which
was a self-forking kernel thread responsible for all the write-back in old
Linux kernels. It was turned into per-block device BDI threads, and
'sync_supers' was a left-over. Thus, R.I.P, pdflush as well.

Shawn Guo 68b0562df9 ARM: imx: enable emi_slow_gate clock for imx5
The imx5 common clock migration causes a regression with smsc911x
driver on imx53-ard board, where a smsc lan9220 controller gets
connected on imx53 with EIM interface.  EIM needs clock emi_slow_gate
to be functional.  In the new imx5 clock driver, there is no use count
incremented for the clock by enabling it, so the framework closes the
clock at late init time and makes EIM stop working then.

Enable emi_slow_gate in clock driver initialization to fix the
regression.

David Ahern 6b118e92cc perf kvm top: Limit guest kernel info message to once
'perf kvm top' shows a continual flurry of:
    Can't find guest [5201]'s kernel information

if it can't find the guest info and with a lot of VMs running a user has no
chance of reading them all. Limit message to once per guest.

David Ahern ee8dd3ca43 perf tools: Change strlist to use the new rblist
Replaces the direct use of rbtree code with the rblist API. In the end
the patch is a no-op on strlist functionality; the API for strlist is
not changed, only its implementaton.

David Ahern 347ed9903a perf kvm: Use strtol for walking guestmount directory
Only want to process directories under the guestmnount directory that
have a pid as a name (ie, all digits). Other entries in the guestmount
directory should be ignored.  There is already a check that requires the
first character of each entry to be a digit, but atoi is used to convert
the directory name to a pid. For example if guestmount contains a
directory with the name 1foo, atoi converts it to a pid of 1 and a
machine is created with a pid of 1. This is wrong; this directory really
should be ignored. Use strtol to do that.

David Ahern 56e6f602aa perf tool: Save cmdline from user in file header vs what is passed to record
A number of builtin commands process some user args and then pass the rest to
cmd_record. cmd_record then saves argc/argv that it receives into the header of
the perf data file. But this loses the arguments handled by the first command
-- ie., the real command line from the user. This patch saves the command line
as typed by the user rather than what was passed to cmd_record.

As an example consider the command:
$ perf kvm --guest --host --guestmount=/tmp/guest-mount record
    -fo /tmp/perf.data -ag -- sleep 10

Currently the command saved to the header is:
    cmdline : /tmp/p3.5/perf record -o perf.data.kvm -fo /tmp/perf.data -ag -- sleep 1

(ignore the duplicated -o -- the first would be yet another bug with perf-kvm).

With this patch the command line saved to the header is:
cmdline : /tmp/p3.5/perf kvm --guest --host --guestmount=/tmp/guest-mount
    record -fo /tmp/perf.data -ag -- sleep 1

v2: simplified to saving the command in parse_options per Stephane's suggestion

Takashi Iwai fcfb7866af ALSA: emu10k1: Avoid access to invalid pages when period=1
When period=1, the driver tries to allocate a bit bigger buffer than
requested by the user due to the irq latency tolerance.  This may lead
to accesses over the actually allocated pages.

This patch adds a check of the page index and assigns the silent page
when it's over the given buffer size.

  arch/x86/platform and into drivers/platform/olpc.

  OLPC machines are now ARM-based (which means lots of x86 and ARM

  sense to go through a separate OLPC tree after getting the appropriate
  review/ACKs."

  x86: OLPC: switch over to using new EC driver on x86
  Platform: OLPC: add a suspended flag to the EC driver
  Platform: OLPC: turn EC driver into a platform_driver
  Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it
