Pull perf fixes from Thomas Gleixner:
 "Three fixlets for perf:

   - Return the proper error code if aux buffers for a event are not
     supported.

   - Calculate the probe offset for inlined functions correctly

   - Update the Skylake DTLB load/store miss event so it can count 1G
     TLB entries as well"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf probe: Fix probe definition for inlined functions
  perf/x86/intel: Add 1G DTLB load/store miss support for SKL
  perf/aux: Correct return code of rb_alloc_aux() if !has_aux(ev)
