  SVN rev 210922 on 2010-08-06 09:25:42Z by jchandra
  
  Fix issue reported by alc :
  
   MIPS doesn't really need to use atomic_cmpset_int() in situations like
   this because the software dirty bit emulation in trap.c acquires
   the pmap lock.  Atomics like this appear to be a carryover from i386
   where the hardware-managed TLB might concurrently set the modified bit.
