Merge tag 'arm64-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64

Pull ARM64 updates from Catalin Marinas:

 - Generic execve, kernel_thread, fork/vfork/clone.

 - Preparatory patches for KVM support (initialising EL2 mode for later
   installing KVM support, hypervisor stub).

 - Signal handling corner case fix (alternative signal stack set up for
   a SEGV handler, which is raised in response to RLIMIT_STACK being
   reached).

 - Sub-nanosecond timer error fix.
