This series enables perf branch stack sampling support on arm64 via a

on BRBE can be found in the Arm ARM[1] chapter D18.

I've picked up this series from Anshuman. v19 and later versions have
been reworked quite a bit by Mark and myself. The bulk of those changes
are in patch 5.

Applied the '__init_el2_fgt' label cleanup to arm64 (for-next/entry), thanks!

[2/5] arm64: el2_setup.h: Make __init_el2_fgt labels consistent, again
