I tested this branch with the arm64 kernel and runs ok (I get couple
of compiler warnings because reparent_to_kthread and
__set_special_pids are no longer used with the removal of daemonize).

I have three arm64 patches on this branch:

git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64.git execve

Catalin Marinas (3):
      arm64: Use generic kernel_thread() implementation
      arm64: Use generic kernel_execve() implementation
      arm64: Use generic sys_execve() implementation
