Merge branch 'misc.compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull alpha syscall cleanups from Al Viro: "A couple of SYSCALL_DEFINE conversions and removal of pointless (and bitrotted) piece stuck in ret_from_kernel_thread since the kernel_exceve/kernel_thread conversions six years ago" * 'misc.compat' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: alpha: get rid of pointless insn in ret_from_kernel_thread alpha: switch pci syscalls to SYSCALL_DEFINE
