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.
