275d1554aa Abolition of bcopy, ovbcopy, bcmp, and bzero, phase one.
bcopy(x, y, z) ->  memcpy(y, x, z)
ovbcopy(x, y, z) -> memmove(y, x, z)
   bcmp(x, y, z) ->  memcmp(x, y, z)
  bzero(x, y)    ->  memset(x, 0, y)

1a8c7604f4 initial import of the new virtual memory system, UVM, into -current.
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

7263209ce6 Make each disk and tape driver define its own read and write functions.

644f409712 Properly initialize the credentials fields in the buffer used in physio().
Actually use the credentials of `curproc' when doing IO (among other things,
this allows us to read /dev/drum when swapping on an NFS mounted file).
