Subject: [PATCH v4 48/71] x86/boot: Switch to new Intel CPU model defines
Date: Wed, 24 Apr 2024 11:15:28 -0700
Message-ID: <20240424181528.42083-1-tony.luck@intel.com>

New CPU #defines encode vendor and family as well as model but
boot code doesn't have all the infrastucture to use them. Hard
code the one CPU model number used here.
