      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."

      Pull SCSI updates from James Bottomley:
       "This is primarily another round of driver updates (lpfc, bfa, fcoe,
        ipr) plus a new ufshcd driver.  There shouldn't be anything
        controversial in here (The final deletion of scsi proc_ops which
        caused some build breakage has been held over until the next merge
        window to give us more time to stabilise it).
      
        I'm afraid, with me moving continents at exactly the wrong time,
        anything submitted after the merge window opened has been held over to
        the next merge window."
