[GIT PULL] arm64 fixes for -rc4

[Will Deacon <will@kernel.org>]

Hi Linus,

We've got a steady trickle of arm64 fixes coming in, but I figured it
was better to send you what we've collected so far rather than keep
waiting for it to settle down. I've already queued some more for next
week.

Anyway, in this batch we've got a couple of hibernation fixes, a couple
of minor MTE fixes, some per-cpu codegen fixes (which were found as part
of Mark's series adding preemptible this_cpu_*() operations) and a fix
for the Arm CMN PMU driver. The summary is in the tag,

Cheers,

Will

- Fix MTE ptrace documentation to reflect the de-facto ABI behaviour

- Fix pthread_join() usage in MTE selftest

- Fix port selection in the Arm CMN PMU driver
