Subject: [PATCH v2 0/7] perf/x86/amd: Miscellaneous updates

Hi,

Please merge:

Patch 1/7 restores 'perf stat -a' behaviour to program the uncore PMU
to count all CPU threads.

Patch 2/7 fixes setting the proper count when sampling Large Increment
per Cycle events / 'paired' events.

The next 4 patches fix IBS Fetch sampling on F17h and some other IBS
fine tuning, the last one greatly reducing the number of interrupts
when large sample periods are specified.

Finally, patch 7/7 extends Family 17h RAPL support to also work on
compatible F19h machines.

Thanks,

Kim

v2: Added this cover letter.  The only patch that changed in this
new submission is the fix for IBS Fetch sampling, which got a new
family check after testing on some other family machines.
