Subject: [PATCH v2 0/3] tools perf: Add branch speculation info

AMD Last Branch Record Extension Version 2 (LbrExtV2) provides branch
speculation information and the perf UAPI is extended to provide this in
a generic way. Update the tools headers and perf tool to be able to show
this additional information.

The LbrExtV2 enablement and UAPI changes can be found at:
https://lore.kernel.org/all/cover.1660211399.git.sandipan.das@amd.com/

Previous versions can be found at:
v1: https://lore.kernel.org/all/cover.1660217326.git.sandipan.das@amd.com/

Changes in v2:
- Drop msr-index.h related changes for now.
- Rebase on top of latest perf/core.
- Fix UAPI breakage introduced by the ARM64 BRBE changes to perf branch
  entry.

Sandipan Das (3):
  tools headers uapi: Sync perf_event.h with kernel sources
  perf script: Show branch speculation info
  perf session: Show branch speculation info in raw dump
