Pull up following revision(s) (requested by skrll in ticket #315):
        sys/arch/arm/arm32/vm_machdep.c: 1.71-1.72
In vmapbuf use pmap_enter(pmap_kernel(), ...) and not pmap_kenter_pa as the
former handles multiple mappings for VIPT AND VIVT correctly whereas the latter
doesn't work for VIVT. PR port-shark/52102
>From skrll@. Tested by martin@ and me.
--
Fix eva argument to pmap_remove and passed prot bits in flags for
pmap_enter, i.e. fix previous.
