Linus,

please pull the latest perf/urgent updates and fixes from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-2020-04-05

up to: 7dc41b9b99cd: Merge tag 'perf-urgent-for-mingo-5.7-20200403' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/urgent

perf updates all over the place:

core:

- Support for cgroup tracking in samples to allow cgroup based
analysis

tools:

- Support for cgroup analysis

- Commandline option and hotkey for perf top to change the sort order

- A set of fixes all over the place

- Various build system related improvements

- Updates of the X86 pmu event JSON data

- Documentation updates

Thanks,

tglx
