      Pull virtio S3 support patches from Amit Shah:
 "Turns out S3 is not different from S4 for virtio devices: the device
  is assumed to be reset, so the host and guest state are to be assumed
  to be out of sync upon resume.  We handle the S4 case with exactly the
  same scenario, so just point the suspend/resume routines to the
  freeze/restore ones.

  Once that is done, we also use the PM API's macro to initialise the
  sleep functions.

  A couple of cleanups are included: there's no need for special thaw
  processing in the balloon driver, so that's addressed in patches 1 and
  2.

  Testing: both S3 and S4 support have been tested using these patches
  using a similar method used earlier during S4 patch development: a
  guest is started with virtio-blk as the only disk, a virtio network
  card, a virtio-serial port and a virtio balloon device.  Ping from
  guest to host, dd /dev/zero to a file on the disk, and IO from the
  host on the virtio-serial port, all at once, while exercising S4 and
  S3 (separately) were tested.  They all continue to work fine after
  resume.  virtio balloon values too were tested by inflating and
  deflating the balloon."

Pulling from Amit, since Rusty is off getting married (and presumably
shaving people).

      Pull second try at vfs part d#2 from Al Viro:
 "Miklos' first series (with do_lookup() rewrite split into edible
  chunks) + assorted bits and pieces.

  The 'untangling of do_lookup()' series is is a splitup of what used to
  be a monolithic patch from Miklos, so this series is basically "how do
  I convince myself that his patch is correct (or find a hole in it)".
  No holes found and I like the resulting cleanup, so in it went..."

      Pull perf updates and fixes from Ingo Molnar:
 "It's mostly fixes, but there's also two late items:

   - preliminary GTK GUI support for perf report
   - PMU raw event format descriptors in sysfs, to be parsed by tooling

  The raw event format in sysfs is a new ABI.  For example for the 'CPU'
  PMU we have:

    aldebaran:~> ll /sys/bus/event_source/devices/cpu/format/*
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/any
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/cmask
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/edge
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/event
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/inv
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/offcore_rsp
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/pc
    -r--r--r--. 1 root root 4096 Mar 31 10:29 /sys/bus/event_source/devices/cpu/format/umask

  those lists of fields contain a specific format:

    aldebaran:~> cat /sys/bus/event_source/devices/cpu/format/offcore_rsp
    config1:0-63

  So, those who wish to specify raw events can now use the following
  event format:

    -e cpu/cmask=1,event=2,umask=3

  Most people will not want to specify any events (let alone raw
  events), they'll just use whatever default event the tools use.

  But for more obscure PMU events that have no cross-architecture
  generic events the above syntax is more usable and a bit more
  structured than specifying hex numbers."

 "This is primarily another round of driver updates (lpfc, bfa, fcoe,

      vfs: split __lookup_hash · bad61189
      Miklos Szeredi authored 
      Split __lookup_hash into two component functions:

 lookup_dcache - tries cached lookup, returns whether real lookup is needed
 lookup_real - calls i_op->lookup

This eliminates code duplication between d_alloc_and_lookup() and
d_inode_lookup().
