[PATCH v3 0/8] perf tools amd ibs: Fixes + Zen6 enhancements

[Ravi Bangoria]

o Fix kernel version check in perf IBS unit test.
o On Zen6 and newer platforms, skip perf unit test that assumes IBS don't
  have hardware-assisted privilege filter.
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

 - Instead of removing the priv modifier unit test completely, skip
   it on platforms that supports hardware privilege filtering. (Namhyung)
 - Rebased the series on latest perf-tools-next/perf-tools-next.
