      ASoC: set idle_bias_off=1 for all platform DAPM contexts · 3fec6b6d
      Stephen Warren authored
      
      
      The ASoC core currently defaults to using STANDBY rather than OFF for
      idle ASoC platform devices, which causes a permanent pm_runtime_get() on
      them. This keeps the device active unnecessarily. This can be especially
      problematic when the ASoC platform device and DAI device are the same
      device.
      
      The distinction between OFF and STANDBY is likely not relevant for ASoC
      platform drivers, since they aren't analog devices. So, solve this issue
      by hard-coding idle_bias_off = 1 for all ASoC platform devices. If this
      turns out to be a problem, this value could be sourced from the
      snd_soc_platform_driver, similarly to soc_probe_codec().
      
      Note: Prior to this change, this caused a large (10) runtime_active count
      for the Tegra I2S controller even when not in use, and a leak in that
      value as streams were started and stopped. This change probably hides a
      bug.

      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

      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."

      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().

      and if d_need_lookup() had already been false the first time around, it
      will remain false on the second call as well.

      d_lookup() *will* fail after successful d_invalidate(), if we are
      holding i_mutex all along.  IOW, we don't need to jump back to
      l: - we know what path will be taken there and can do that (i.e.
      d_alloc_and_lookup()) directly.

      Duplicate the revalidation-related parts into if (!dentry) branch.
      Next step will be to pull them under i_mutex.
      
      This and the next 8 commits are more or less a splitup of patch
      by Miklos; folks, when you are working with something that convoluted,
      carve your patches up into easily reviewed steps, especially when
      a lot of codepaths involved are rarely hit...
