Subject: [PATCH 5/7] x86: introduce fake processor type to mark sub-arch entries in cpu_arch[]
Date: Thu, 30 Jun 2022 14:54:56 +0200 [thread overview]
Message-ID: <698f66c4-93f1-0627-1958-4ef83c7d0326@suse.com> (raw)
In-Reply-To: <01f502ff-5b51-86d3-ed54-646df7d22037@suse.com>
This is in preparation of dropping the leading . from the strings.
While there also move PROCESSOR_GENERIC{32,64} from the middle of AMD
entries to near the top.
