[PATCH 0/2] sched/wait: abort_exclusive_wait() should pass TASK_NORMAL to wake_up()

To clarify, this can't fix the lock_page() hang reported by Bart,
__wait_on_bit_lock() is fine even if abort_exclusive_wait() is buggy.
Still should be fixed I think. And perhaps we should simply kill
abort_exclusive_wait() ? See 2/2.
And this reminds me... I still fail to understand why/how the commit
68985633bccb60 "sched/wait: Fix signal handling in bit wait helpers"
can help. Apart from s/return 1/return -EINTR/. Peter, do you have any
theory?
Oleg.
