Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 regression fix from Will Deacon:
"Apologies for the _extremely_ late pull request here, but we had a
'perf' (i.e. CPU PMU) regression on the Apple M1 reported on Wednesday
[1] which was introduced by bd2756811766 ("perf: Rewrite core context
handling") during the merge window.
Mark and I looked into this and noticed an additional problem caused
by the same patch, where the 'CHAIN' event (used to combine two
adjacent 32-bit counters into a single 64-bit counter) was not being
filtered correctly. Mark posted a series on Thursday [2] which
addresses both of these regressions and I queued it the same day.
The changes are small, self-contained and have been confirmed to fix
the original regression.
Summary:
- Fix 'perf' regression for non-standard CPU PMU hardware (i.e. Apple
M1)"
