Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
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)
