Module Name:    src
Committed By:   reinoud
Date:           Wed Aug 24 12:54:47 UTC 2011

Modified Files:
        src/sys/arch/usermode/include: vmparam.h
        src/sys/arch/usermode/usermode: pmap.c

Log Message:
Swap userland code and kvm spaces so that userland lives from VM_MIN_ADDRESS
to VM_MAXUSER_ADDRESS and KVM is above that.

Note that the userspace is surrounded by a configurable amount of
non-accessible barrier space to prevent accidental out-of-boundaries access
even when reading.
