Alan Cox 7a35a21e7b Reimplement the reclamation of PV entries. Specifically, perform ... reclamation synchronously from get_pv_entry() instead of asynchronously as part of the page daemon. Additionally, limit the reclamation to inactive pages unless allocation from the PV entry zone or reclamation from the inactive queue fails. Previously, reclamation destroyed mappings to both inactive and active pages. get_pv_entry() still, however, wakes up the page daemon when reclamation occurs. The reason being that the page daemon may move some pages from the active queue to the inactive queue, making some new pages available to future reclamations. Print the "reclaiming PV entries" message at most once per minute, but don't stop printing it after the fifth time. This way, we do not give the impression that the problem has gone away.
