Merge tag 'arm64-uapi' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64
Pull arm64 uapi disintegration from Catalin Marinas:
"UAPI headers for arm64 together with some clean-up to make it
possible:
- Do not export the COMPAT_* definitions to user
- Simplify the compat unistd32.h definitions and remove the
__SYSCALL_COMPAT guard
- Disintegrate the arch/arm64/include/asm/* headers"
* tag 'arm64-uapi' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64:
UAPI: (Scripted) Disintegrate arch/arm64/include/asm
arm64: Do not export the compat-specific definitions to the user
arm64: Do not include asm/unistd32.h in asm/unistd.h
arm64: Remove unused definitions from asm/unistd32.h
