Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull ARM64 updates from Catalin Marinas:
- CPU suspend support on top of PSCI (firmware Power State Coordination
Interface)
- jump label support
- CMA can now be enabled on arm64
- HWCAP bits for crypto and CRC32 extensions
- optimised percpu using tpidr_el1 register
- code cleanup
