[1/1] Export __lock_page_killable()

[Evgeniy Polyakov <johnpol@2ka.mipt.ru>]

Hi.

There are users, who would like to use lock_page_killable() in modules,
so far there are no users in kernel, but for consistency it can be
exported without them.

Not that it is particulary needed, but copying page_waitqueue() in
modules is frowned upon and unlikely to be exported either.

As a side note, do we want interruptible and time limited locking for
those who knows what is being done?
