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)
