      HID: roccat: potential out of bounds in pyra_sysfs_write_settings() · 606185b2
      Dan Carpenter authored
      
      
      This is a static checker fix.  We write some binary settings to the
      sysfs file.  One of the settings is the "->startup_profile".  There
      isn't any checking to make sure it fits into the
      pyra->profile_settings[] array in the profile_activated() function.
      
      I added a check to pyra_sysfs_write_settings() in both places because
      I wasn't positive that the other callers were correct.

      mutex: Always clear owner field upon mutex_unlock() · a63b03e2
      Chris Wilson authored
      Currently if DEBUG_MUTEXES is enabled, the mutex->owner field is only
      cleared iff debug_locks is active. This exposes a race to other users of
      the field where the mutex->owner may be still set to a stale value,
      potentially upsetting mutex_spin_on_owner() among others.

      perf/x86/uncore/hsw-ep: Handle systems with only two SBOXes · 5306c31c
      Andi Kleen authored
      
      
      There was another report of a boot failure with a #GP fault in the
      uncore SBOX initialization. The earlier work around was not enough
      for this system.
      
      The boot was failing while trying to initialize the third SBOX.
      
      This patch detects parts with only two SBOXes and limits the number
      of SBOX units to two there.
      
      Stable material, as it affects boot problems on 3.18.

      perf/x86_64: Improve user regs sampling · 86c269fe
      Andy Lutomirski authored
      
      
      Perf reports user regs for kernel-mode samples so that samples can
      be backtraced through user code.  The old code was very broken in
      syscall context, resulting in useless backtraces.
      
      The new code, in contrast, is still dangerously racy, but it should
      at least work most of the time.

      perf: Move task_pt_regs sampling into arch code · 88a7c26a
      Andy Lutomirski authored
      
      
      On x86_64, at least, task_pt_regs may be only partially initialized
      in many contexts, so x86_64 should not use it without extra care
      from interrupt context, let alone NMI context.
      
      This will allow x86_64 to override the logic and will supply some
      scratch space to use to make a cleaner copy of user regs.
