Modified files:
sys/vm vm_map.c
Log:
Two small changes to vm_map_pmap_enter():
1) Eliminate an unnecessary check for fictitious pages. Specifically,
only device-backed objects contain fictitious pages and the object is
not device-backed.
2) Change the types of "psize" and "tmpidx" to vm_pindex_t in order to
prevent possible wrap around with extremely large maps and objects,
respectively. Observed by: tegge (last summer)
