linux-next: manual merge of the signal tree with the sparc tree

Hi Al,

Today's linux-next merge of the signal tree got a conflict in
arch/sparc/kernel/sys_sparc_64.c between commit 517ffce4e1a0 ("sparc64:
Make montmul/montsqr/mpmul usable in 32-bit threads") from the sparc tree
and commit 2f12af35a988 ("sparc64: switch to generic kernel_execve()")
from the signal tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
