Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/signal
Pull first series of signal handling cleanups from Al Viro:
"This is just the first part of the queue (about a half of it);
assorted fixes all over the place in signal handling.
This one ends with all sigsuspend() implementations switched to
generic one (->saved_sigmask-based).
With this, a bunch of assorted old buglets are fixed and most of the
missing bits of NOTIFY_RESUME hookup are in place. Two more fixes sit
in arm and um trees respectively, and there's a couple of broken ones
that need obvious fixes - parisc and avr32 check TIF_NOTIFY_RESUME
only on one of two codepaths; fixes for that will happen in the next
series"

unicore32: if there's no handler we need to restore sigmask, syscall or no syscall
xtensa: add handling of TIF_NOTIFY_RESUME
microblaze: drop 'oldset' argument of do_notify_resume()
microblaze: handle TIF_NOTIFY_RESUME
score: add handling of NOTIFY_RESUME to do_notify_resume()
m68k: add TIF_NOTIFY_RESUME and handle it.
sparc: kill ancient comment in sparc_sigaction()

sh: missing checks of __get_user()/__put_user() return values
sparc: missing checks of __get_user()/__put_user() return values
avr32: struct old_sigaction is never used
m32r: struct old_sigaction is never used
xtensa: xtensa_sigaction doesn't exist
alpha: tidy signal delivery up
score: don't open-code force_sigsegv()
