    sys/i386/i386        identcpu.c 
  Log:
  Correct the input/output/clobber specifications for the cpuid
  instruction.  Stefan Keller <dres@earth.serd.org> noticed that CPU
  identification was broken when compiled with -O2, and tracked it
  down to the asm statement, which was storing values into memory
  without specifying that memory was modified.  He submitted a patch
  which added "memory" as a clobber, but I refined it further to
  arrive at this version.
