Modified files:
sys/amd64/amd64 pmap.c
sys/i386/i386 pmap.c
Log:
When support for 2MB/4MB pages was added in revision 1.148 an error was
made in pmap_protect(): The pmap's resident count should not be reduced
unless mappings are removed.
The errant change to the pmap's resident count could result in a later
pmap_remove() failing to remove any mappings if the errant change has set
the pmap's resident count to zero.
