CVS commit: src/sys/arch/usermode/usermode

Module Name:    src
Committed By:   reinoud
Date:           Fri Sep  9 12:28:05 UTC 2011

Modified Files:
        src/sys/arch/usermode/usermode: pmap.c

Log Message:
Implement TBL functionality by remembering if its mapped in or not before
guessing and adjusting access types.

While here, when we hit a read-access fault and reference the page, also mark
it for executable when its permissions permit it. Distinguising between the
two is neigh impossible as we need to guess/derive the access the process
tried to have to the memory: we dont know if its a read/write/exec try.

Also clean up some debug messages.
