Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull more arm64 updates from Catalin Marinas:
- Silence module allocation failures when CONFIG_ARM*_MODULE_PLTS is
enabled. This requires a check for __GFP_NOWARN in alloc_vmap_area()
- Improve/sanitise user tagged pointers handling in the kernel
- Inline asm fixes/cleanups
