    Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux into next · cc07aabc
    Linus Torvalds authored
    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.
