  Modified files:
    sys/kern             sys_pipe.c 
  Log:
  Do not use pmap_kextract() to find out the physical address of a user
  belong to a user virtual address; while this happens to work on some
  architectures, it can't on sparc64, since user and kernel virtual
  address spaces overlap there (the distinction between them is done via
  separate address space identifiers).
  
  Instead, look up the page in the vm_map of the process in question.
