[PATCH v2 0/8] perf tools amd ibs: Fixes + Zen6 enhancements

[Ravi Bangoria <ravi.bangoria@amd.com>]

o Fix kernel version check in perf IBS unit test.
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 Zen6 and future platforms extends IBS OP with Streaming-Store and
  Remote-Socket indicators for load/store instructions. Add decoding
  support for these new bits.
o Document new IBS features in perf-amd-ibs man page
