Merge remote-tracking branch 'torvalds/master' into perf/core
To pick up the fixes sent for v5.12 and continue development based on v5.12-rc2, i.e. without the swap on file bug. This also gets a slightly newer and better tools/perf/arch/arm/util/cs-etm.c patch version, using the BIT() macro, that had already been slated to v5.13 but ended up going to v5.12-rc1 on an older version.
