[Andrew Morton]

The quilt patch titled
     Subject: sched/psi: export psi_memstall_{enter,leave}
has been removed from the -mm tree.  Its filename was
     sched-psi-export-psi_memstall_enterleave.patch

This patch was dropped because it was merged into mainline or a subsystem tree

To properly account for all refaults from file system logic, file systems
need to call psi_memstall_enter directly, so export it.
