[Ingo Molnar]

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

   # HEAD: e680a41fcaf07ccac8817c589fc4824988b48eac Merge tag 'perf-core-for-mingo-5.5-20191128' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

Mostly fixes:


 - Make /sys/devices/cpu/rdpmc based RDPMC enforcement more instantaneous

 - decoder: Update the Intel opcode map

 - Various tooling fixes, including a few late optimizations and cleanups.

 Thanks,

	Ingo
