  SVN rev 204312 on 2010-02-25 14:51:06Z by nwhitehorn
  
  Fix another bug involving /dev/mem and the OEA64 scratchpage. When
  the scratchpage is updated, the PVO's physical address is updated as well.
  This makes pmap_extract() begin returning non-zero values again, causing
  the panic partially fixed in r204297. Fix this by excluding addresses
  beyond virtual_end from consideration as KVA addresses, instead of allowing
  addresses up to VM_MAX_KERNEL_ADDRESS.
