Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal
Pull misc syscall fixes from Al Viro: - compat syscall fixes (discussed back in December) - a couple of "make life easier for sigaltstack stuff by reducing inter-tree dependencies" - fix up compiler/asmlinkage calling convention disagreement of sys_clone() - misc * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal: sys_clone() needs asmlinkage_protect make sure that /linuxrc has std{in,out,err} x32: fix sigtimedwait x32: fix waitid() switch compat_sys_wait4() and compat_sys_waitid() to COMPAT_SYSCALL_DEFINE switch compat_sys_sigaltstack() to COMPAT_SYSCALL_DEFINE CONFIG_GENERIC_SIGALTSTACK build breakage with asm-generic/syscalls.h Ensure that kernel_init_freeable() is not inlined into non __init code
