linux-next: manual merge of the signal tree with Linus' tree

Hi Al,

Today's linux-next merge of the signal tree got a conflict in
arch/powerpc/kernel/entry_64.S between commit c58ce2b1e3c7 ("ppc64: fix
missing to check all bits of _TIF_USER_WORK_MASK in preempt") from Linus'
tree and commit d07644a97726 ("powerpc: missing NOTIFY_RESUME check on
64bit if CONFIG_PREEMPT is set") from the signal tree.

I *think* that the former is a superset of the latter, so I just used the
former.
