    sys/i386/i386        identcpu.c initcpu.c 
    sys/i386/include     md_var.h 
  Log:
  Begin promoting the AMD-originated feature flags to first class flags, now
  that newer Intel cpu hardware implements them too.  This includes things
  like the NX (pte no-execute) flag for execute protection.  We'll need to
  reference this for implementing no-exec in pmap.c at some point.
  
  Some feature flags are duplicated in both the Intel-orignated bits and
  the AMD bits.  Suppress the the duplicates correctly - the old code
  assumed they were a 1:1 mapping which is not correct.  We can't just mask
  off the bits present in cpu_feature.
  
  Converge with amd64 where this originated from.
  
  Intel cpu's that implement any AMD features will report them in dmesg now.
