Pull signal handling cleanups from Al Viro:
 "This is the first pile; another one will come a bit later and will
  contain SYSCALL_DEFINE-related patches.

   - a bunch of signal-related syscalls (both native and compat)
     unified.

   - a bunch of compat syscalls switched to COMPAT_SYSCALL_DEFINE
     (fixing several potential problems with missing argument
     validation, while we are at it)

   - a lot of now-pointless wrappers killed

   - a couple of architectures (cris and hexagon) forgot to save
     altstack settings into sigframe, even though they used the
     (uninitialized) values in sigreturn; fixed.

   - microblaze fixes for delivery of multiple signals arriving at once

   - saner set of helpers for signal delivery introduced, several
     architectures switched to using those."

Commit def8203 ("microblaze idle: delete pm_idle") introduced the following
compile error:

	arch/microblaze/kernel/process.c: In function 'cpu_idle':
	arch/microblaze/kernel/process.c:100: error: 'idle' undeclared (first use in this function)
	arch/microblaze/kernel/process.c:100: error: (Each undeclared identifier is reported only once
	arch/microblaze/kernel/process.c:100: error: for each function it appears in.)
	arch/microblaze/kernel/process.c:106: error: implicit declaration of function 'idle'

This patch fixes it.
