Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- ZONE_DMA32 initialisation fix when memblocks fall entirely within the
first GB (used by ZONE_DMA in 5.5 for Raspberry Pi 4).
- Couple of ftrace fixes following the FTRACE_WITH_REGS patchset.
- access_ok() fix for the Tagged Address ABI when called from from a
kernel thread (asynchronous I/O): the kthread does not have the TIF
flags of the mm owner, so untag the user address unconditionally.
- KVM compute_layout() called before the alternatives code patching.
- Minor clean-ups.
