-A address Dumps the vm_amap structure found at address.
-E address Dumps the vm_map_entry structure found at address.
-S address Dumps the vmspace structure found at address.
-V address Dumps the vm_map structure found at address.
This required reorganizing the code a little, which led to some
cleanup (yay!). These new methods are executed without any extra
privileges, so you need read access on /dev/mem or on the kernel core
into which you are digging.
This should be useful for, eg, examining amaps are corrupt when being
destroyed, which can cause a kernel panic (and, hence, are no longer
connected to a map entry, or the map entry is no longer connected to a
vm_map/vmspace).
The options in the man page have also been reorganized.
