Log Message:
Pull up revision 1.29 (requested by yamt in ticket #271):
fix a amap_wirerange deadlock problem by re-introducing
PG_RELEASED for anon pages.  PR/23171 from Christian Limpach.
for details, see discussion filed in the PR database.
uvm_anon_release: a new function to free anon-owned PG_RELEASED page.
uvm_anfree: we can't wait for the page here because the caller might hold
        amap lock.  instead, just mark the page as PG_RELEASED.
        who unbusy the page should check the PG_RELEASED.
uvm_aio_aiodone: uvm_anon_release() instead of uvm_page_unbusy()
        if appropriate.
uvmfault_anonget: check PG_RELEASED.
