From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Today's linux-next build (x86_64 allmodconfig) failed like this:
kernel/user-return-notifier.c: In function
'fire_user_return_notifiers': kernel/user-return-notifier.c:45:
error: expected expression before ')' token
Introduced by commit 7c68af6e32c73992bad24107311f3433c89016e2
("core, x86: Add user return notifiers") from the tip and kvm trees
but revealed by commit e0fdb0e050eae331046385643618f12452aa7e73
("percpu: add __percpu for sparse") from the percpu tree.
Before that percpu tree commit, "put_cpu_var()" would compile
without error (even though it really needs a parameter).
