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
