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.
