Merge branch 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf fixes from Thomas Gleixner: - plug a memory leak in the intel pmu init code - clang fixes - tooling fix to avoid including kernel headers - a fix for jvmti to generate correct debug information for inlined code - replace backtick with a regular shell function - fix the build in hardened environments * 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: perf/x86/intel: Plug memory leak in intel_pmu_init() x86/asm: Allow again using asm.h when building for the 'bpf' clang target tools arch s390: Do not include header files from the kernel sources perf jvmti: Generate correct debug information for inlined code perf tools: Fix up build in hardened environments perf tools: Use shell function for perl cflags retrieval
