    sys/arm/arm          pmap.c 
  Log:
  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.
