Alan Cox 270da41581 _pmap_unwire_pte_hold and pmap_remove_page:
Use pmap_TLB_invalidate instead of invltlb_1pg to eliminate
	unnecessary IPIs.

pmap_remove, pmap_protect and pmap_remove_pages:
	Use pmap_TLB_invalidate_all instead of invltlb to eliminate
	unnecessary IPIs.

pmap_copy:
	Use cpu_invltlb instead of invltlb when updating APTDpde.

pmap_changebit:
	Rather than deleting the unused "set bit" option (which may be
	useful later), make pmap_changebit an inline that is used
	by the new pmap_clearbit procedure.

Collectively, the first three changes reduce the number of TLB shootdown
IPIs by 1/3 for a kernel compile.
