  Modified files:
    sys/ia64/ia64        pmap.c 
  Log:
  Fix collision chain termination checks. The result of IA64_PHYS_TO_RR7
  is never 0, so one cannot test for a NULL pointer after a physical
  address is translated into a virtual pointer with said macro. Instead,
  keep the physical address around and test it against 0. Note that
  this obviously implies that a PTE can never be allocated at physical
  address 0. This isn't exactly guaranteed, but hasn't been a problem
  so far. We test the physical address against 0 for as long as the ia64
  port exists...
