Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"I'd been collecting these whilst we debugged a CPU hotplug failure,
but we ended up diagnosing that one to tglx, who has taken a fix via
the -tip tree separately.
We're seeing some NFS issues that we haven't gotten to the bottom of
yet, and we've uncovered some issues with our backtracing too so there
might be another fixes pull before we're done.
Summary:
- Ensure we have a guard page after the kernel image in vmalloc
- Fix incorrect prefetch stride in copy_page
- Ensure irqs are disabled in die()
- Fix for event group validation in QCOM L2 PMU driver
- Fix requesting of PMU IRQs on AMD Seattle
- Minor cleanups and fixes"
