When I made that comment it was about a patch series that used
bitfields to decode the subfields in Intel model specific MSRs.  I
think that's true of use in this series too.

I think most of these are for MSR decode. The one mentioned in
this thread: "union ifs_scan_hashes_status_gen2 {" definitely is.

Are there any that are not for MSRs? I'd also claim "Intel
specific" if there are some decoding parts of the Intel scan
file format.
