Modified files:
sys/amd64/amd64 pmap.c
sys/amd64/include pmap.h
Log:
Add support for automatic promotion of 4KB page mappings to 2MB page
mappings. Automatic promotion can be enabled by setting the tunable
"vm.pmap.pg_ps_enabled" to a non-zero value. By default, automatic
promotion is disabled. (Expect this to change.)
