src/sys/uvm: uvm_km.c
Log Message:
uvm_km_pgremove_intrsafe(): properly compute the size to pmap_kremove()
(do not trucate it to the first __PGRM_BATCH pages per batch): if we were
given a sparse mapping, we could leave mappings in place.
Note that this doesn't seem to be a problem right now: I added a KASSERT
in my private tree to see if uvm_km_pgremove_intrsafe() would use a
too short size, and it didn't fire.
