Linus,

please pull the latest perf-urgent-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus

Another small set of perf tooling fixes and updates:

. Revert "perf pmu: Fix pmu events parsing rule", as it broke Intel PT
event description parsing (Arnaldo Carvalho de Melo)

. Sync x86's cpufeatures.h and kvm UAPI headers with the kernel sources,
suppressing the ABI drift warnings (Arnaldo Carvalho de Melo)

- Remove duplicated entry for westmereep-dp in Intel's mapfile.csv (William Cohen)

- Fix typo in 'perf bench numa' options description (Yisheng Xie)

Thanks,

tglx

------------------>
Arnaldo Carvalho de Melo (4):
tools headers: Sync x86 cpufeatures.h with the kernel sources
tools headers kvm: Sync uapi/linux/kvm.h with the kernel sources
tools headers kvm: Sync ARM UAPI headers with the kernel sources
