Modified Files:
	syssrc/sys/arch/i386/i386: pmap.c

Log Message:
several fixes:
  1.  in pmap_steal_ptp(), don't trylock the pmap that wants a ptp,
      the caller already has it locked.
  2.  do not panic in pmap_enter() due to memory allocation failures when
      the PMAP_CANFAIL flag is given.  to this end, move all such panics
      from the lower-level routines to pmap_enter() and pmap_growkernel()
      where we can check for this flag.
  3.  add #ifdef DIAGNOSTIC around all panics which are only reachable
      if there's a bug or a hardware error.
