freza e2db2efb2e Instead of mapping whole RAM with reserved TLB entries, map just enough
to ensure trap code will work (that is 0 upto ${endkernel}) and leave the
rest to pmap_tlbmiss(). Mapping whole physmem into the kernel wired way
too many TLB entries, see

  http://mail-index.netbsd.org/port-powerpc/2006/10/27/0000.html

for performance analysis. While there, be a bit more descriptive in
pmap_tlbmiss() comment and use macro instead of numeric constant.
