Merge branch 'sched-wait-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull wait_var_event updates from Ingo Molnar: "This introduces the new wait_var_event() API, which is a more flexible waiting primitive than wait_on_atomic_t(). All wait_on_atomic_t() users are migrated over to the new API and wait_on_atomic_t() is removed. The migration fixes one bug and should result in no functional changes for the other usecases" * 'sched-wait-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/wait: Improve __var_waitqueue() code generation sched/wait: Remove the wait_on_atomic_t() API sched/wait, arch/mips: Fix and convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait, fs/ocfs2: Convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait, fs/nfs: Convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait, fs/fscache: Convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait, fs/btrfs: Convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait, fs/afs: Convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait, drivers/media: Convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait, drivers/drm: Convert wait_on_atomic_t() usage to the new wait_var_event() API sched/wait: Introduce wait_var_event()
