Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Will Deacon:
"The main thing here is a long-awaited workaround for a CPU erratum on
ThunderX2 which we have developed in conjunction with engineers from
Cavium/Marvell.
At the moment, the workaround is unconditionally enabled for affected
CPUs at runtime but we may add a command-line option to disable it in
future if performance numbers show up indicating a significant cost
for real workloads.
Summary:
- Work around Cavium/Marvell ThunderX2 erratum #219
- Fix regression in mlock() ABI caused by sign-extension of TTBR1 addresses
- More fixes to the spurious kernel fault detection logic
- Fix pathological preemption race when enabling some CPU features at boot
- Drop broken kcore macros in favour of generic implementations
- Fix userspace view of ID_AA64ZFR0_EL1 when SVE is disabled
- Avoid NULL dereference on allocation failure during hibernation"
