      Linus Torvalds authored
      Pull regmap updates from Mark Brown:
       "Things are really quieting down with the regmap API, while we're still
        seeing a trickle of new features coming in they're getting much
        smaller than they were.  It's also nice to have some features which
        support other subsystems building infrastructure on top of regmap.
        Highlights include:
      
        - Support for padding between the register and the value when
          interacting with the device, sometimes needed for fast interfaces.
        - Support for applying register updates to the device when restoring
          the register state.  This is intended to be used to apply updates
          supplied by manufacturers for tuning the performance of the device
          (many of which are to undocumented registers which aren't otherwise
          covered).
        - Support for multi-register operations on cached registers.
        - Support for syncing only part of the register cache.
        - Stubs and parameter query functions intended to make it easier for
          other subsystems to build infrastructure on top of the regmap API.
      
        plus a few driver updates making use of the new features which it was
        easier to merge via this tree."

      Pull IEEE 1394 (FireWire) subsystem updates post v3.3 from Stefan Richter:
      
       - Some SBP-2 initiator fixes, side product from ongoing work on a target.
      
       - Reintroduction of an isochronous I/O feature of the older ieee1394 driver
         stack (flush buffer completions); it was evidently rarely used but not
         actually unused.  Matching libraw1394 code is already available.

       "which has three neat features:
      
         - PV multiconsole support, so that there can be hvc1, hvc2, etc; This
           can be used in HVM and in PV mode.
      
         - P-state and C-state power management driver that uploads said power
           management data to the hypervisor.  It also inhibits cpufreq
           scaling drivers to load so that only the hypervisor can make power
           management decisions - fixing a weird perf bug.
      
           There is one thing in the Kconfig that you won't like: "default y
           if (X86_ACPI_CPUFREQ = y || X86_POWERNOW_K8 = y)" (note, that it
           all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by
           default is off).  I've a fix to convert that boolean expression
           into "default m" which I am going to post after the cpufreq git
           pull - as the two patches to make this work depend on a fix in Dave
           Jones's tree.
      
         - Function Level Reset (FLR) support in the Xen PCI backend.

         - Kconfig dependencies for Xen PV keyboard and video

      security: optimize avc_audit() common path · 48aab2f7
      Linus Torvalds authored
      avc_audit() did a lot of jumping around and had a big stack frame, all
      for the uncommon case.
      
      Split up the uncommon case (which we really can't make go fast anyway)
      into its own slow function, and mark the conditional branches
      appropriately for the common likely case.
      
      This causes avc_audit() to no longer show up as one of the hottest
      functions on the branch profiles (the new "perf -b" thing), and makes
      the cycle profiles look really nice and dense too.
      
      The whole audit path is still annoyingly very much one of the biggest
      costs of name lookup, so these things are worth optimizing for.  I wish
      we could just tell people to turn it off, but realistically we do need
      it: we just need to make sure that the overhead of the necessary evil is
      as low as possible.
