Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux into next
Pull arm64 updates from Catalin Marinas:
- Optimised assembly string/memory routines (based on the AArch64
Cortex Strings library contributed to glibc but re-licensed under
GPLv2)
- Optimised crypto algorithms making use of the ARMv8 crypto extensions
(together with kernel API for using FPSIMD instructions in interrupt
context)
- Ftrace support
- CPU topology parsing from DT
- ESR_EL1 (Exception Syndrome Register) exposed to user space signal
handlers for SIGSEGV/SIGBUS (useful to emulation tools like Qemu)
- 1GB section linear mapping if applicable
- Barriers usage clean-up
- Default pgprot clean-up
Conflicts as per Catalin.
