Alan Cox dc9250f55c Correct a lock assertion failure in sparc64's pmap_page_is_mapped() that is
a consequence of sparc64/sparc64/vm_machdep.c revision 1.76.  It occurs
when uma_small_free() frees a page.  The solution has two parts: (1) Mark
pages allocated with VM_ALLOC_NOOBJ as PG_UNMANAGED.  (2) Defer the lock
assertion in pmap_page_is_mapped() until after PG_UNMANAGED is tested.
This is safe because both PG_UNMANAGED and PG_FICTITIOUS are immutable
flags, i.e., they do not change state between the time that a page is
allocated and freed.
