Please include a link to the documentation when you cite things like
this.  For example, this is very helpful:

	Several older Intel CPUs have this or a similar erratum.  For
	instance, the "Intel Xeon Processor 5400 Series Specification
	Update" has "AX74 ... Not-Present Page Faults May Set the RSVD
	Flag in the Error Code".

	https://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/xeon-5400-spec-update.pdf

That makes it a *LOT* easier to find the actual erratum and its text.  I
honestly also woudln't mind if you just copy a chunk of the problem text
verbatim into the changelog.  Intel does have a habit of updating text
in documents like that and it's quite handy to have a snapshot of what
you were reading when you wrote the patch.
