The changed files were only including linux/module.h for the
EXPORT_SYMBOL infrastructure, and nothing else. Revector them
onto the isolated export header for faster compile times.
Nothing to see here but a whole lot of instances of:
-#include <linux/module.h>
+#include <linux/export.h>
This commit is only changing the kernel dir; next targets
will probably be mm, fs, the arch dirs, etc.

Instead of using per_cpu(..., raw_smp_processor_id()), use
__get_cpu_var(...).

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 7c68af6e32
("core, x86: Add user return notifiers") from the tip and kvm trees
but revealed by commit e0fdb0e050
("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).

Add a general per-cpu notifier that is called whenever the kernel is
about to return to userspace. The notifier uses a thread_info flag
and existing checks, so there is no impact on user return or context
switch fast paths.
This will be used initially to speed up KVM task switching by lazily
updating MSRs.
