Fix a leak of the wired pages when unwiring of the PROT_NONE-mapped
wired region. Rework the handling of unwire to do the it in batch,
both at pmap and object level.
All commits below are by alc.
MFC r268327:
Introduce pmap_unwire().
MFC r268591:
Implement pmap_unwire() for powerpc.
MFC r268776:
Implement pmap_unwire() for arm.
MFC r268806:
pmap_unwire(9) man page.
MFC r269134:
When unwiring a region of an address space, do not assume that the
underlying physical pages are mapped by the pmap. This fixes a leak
of the wired pages on the unwiring of the region mapped with no access
allowed.
MFC r269339:
In the implementation of the new function pmap_unwire(), the call to
MOEA64_PVO_TO_PTE() must be performed before any changes are made to the
PVO. Otherwise, MOEA64_PVO_TO_PTE() will panic.
MFC r269365:
Correct a long-standing problem in moea{,64}_pvo_enter() that was revealed
by the combination of r268591 and r269134: When we attempt to add the
wired attribute to an existing mapping, moea{,64}_pvo_enter() do nothing.
(They only set the wired attribute on newly created mappings.)
MFC r269433:
Handle wiring failures in vm_map_wire() with the new functions
pmap_unwire() and vm_object_unwire().
Retire vm_fault_{un,}wire(), since they are no longer used.
MFC r269438:
Rewrite a loop in vm_map_wire() so that gcc doesn't think that the variable
"rv" is uninitialized.
MFC r269485:
Retire pmap_change_wiring().
