[PATCH] Add TIF_RESTORE_SIGMASK
We need TIF_RESTORE_SIGMASK in order to support ppoll() and pselect() system calls. This patch originally came from Andi, and was based heavily on David Howells' implementation of same on i386. I fixed a typo which was causing do_signal() to use the wrong signal mask. Signed-off-by: David Woodhouse <dwmw2@infradead.org> Signed-off-by: Andi Kleen <ak@suse.de>
