Subject: [PATCH] x86/cpu: Comment Skylake server stepping too
Date: Fri, 9 Apr 2021 13:10:27 +0100 [thread overview]
Message-ID: <20210409121027.16437-1-andrew.cooper3@citrix.com> (raw)
Further to commit 53375a5a218e ("x86/cpu: Resort and comment Intel
models"), CascadeLake and CooperLake are steppings of Skylake, and make up
the 1st to 3rd generation "Xeon Scalable Processor" line.

It is left as an exercise to the reader to ponder why the 3rd generation Xeon
Scalable brand is formed of both CooperLake and IceLake parts.
