Subject: [PATCH 0/6] perf tools amd ibs: Fixes + future enhancements

o Drop perf unit test that assumes IBS don't have hardware-assisted
  privilege filter. This is now supported.
o Starting with Zen4, the validity of several IBS fields changes. Add
  the required dependency checks when decoding IBS MSRs.
o Future CPUs extend IBS OP with Streaming-Store and Remote-Socket
  indicators for load/store instructions. Add decoding support for
  these new bits.

Patches are prepared on perf-tools-next/perf-tools-next (571d29baa07e).
