Log:
MFC rev 1.90:
Fix a potential bug in pmap :
We used to allocate the domains 0-14 for userland, and leave the domain 15
for the kernel. Now supersections requires the use of domain 0, so we
switched the kernel domain to 0, and use 1-15 for userland.
How it's done currently, the kernel domain could be allocated for a
userland process.
So switch back to the previous way we did things, set the first available
domain to 0, and just add 1 to get the real domain number in the struct pmap.
