Yes, basically if I remember right someone used

PG_GLOBAL instead of PG_G. This caused the wrong bits
to be set.

In general I think its a BAD idea to have two name spaces in the
same section of the system (VM) that have similar define's that mean
different things.


Far better to KEEP the PTE_xxx or for that matter pick something  
else.. Just
NOT PG_xxx
