   # HEAD: f91072ed1b7283b13ca57fcfbece5a3b92726143 perf/core: Fix race in the perf_mmap_close() function

These are the performance events changes for v5.10:

x86 Intel updates:

 - Add Jasper Lake support

 - Add support for TopDown metrics on Ice Lake

 - Fix Ice Lake & Tiger Lake uncore support, add Snow Ridge support

 - Add a PCI sub driver to support uncore PMUs where the PCI resources
   have been claimed already - extending the range of supported systems.

x86 AMD updates:

 - Restore 'perf stat -a' behaviour to program the uncore PMU
   to count all CPU threads.

 - Fix setting the proper count when sampling Large Increment
   per Cycle events / 'paired' events.

 - Fix IBS Fetch sampling on F17h and some other IBS fine tuning,
   greatly reducing the number of interrupts when large sample
   periods are specified.

 - Extends Family 17h RAPL support to also work on compatible
   F19h machines.

Core code updates:

 - Fix race in perf_mmap_close()

 - Add PERF_EV_CAP_SIBLING, to denote that sibling events should be
   closed if the leader is removed.

 - Smaller fixes and updates.

 Thanks,

	Ingo
