Hi Al,
Today's linux-next merge of the signal tree got a conflict in
arch/x86/kernel/signal.c between commit 1ea856be75ce ("x86: Exit RCU
extended QS on notify resume") from the rcu tree and commit 02bf6b04fcd5
("x86: switch uses of TIF_IRET to TIF_NOTIFY_RESUME, kill TIF_IRET") from
the signal tree.
Just context changes. I have fixed it up (see below) and can carry the
fix as necessary.
