The following commit has been merged into the x86/microcode branch of tip: Commit-ID: 28377e56ed22ecce60260eb8afdf0c9837b3505f Gitweb: https://git.kernel.org/tip/28377e56ed22ecce60260eb8afdf0c9837b3505f Author: Jithu Joseph <jithu.joseph@intel.com> AuthorDate: Wed, 16 Nov 2022 19:59:28 -08:00 Committer: Borislav Petkov <bp@suse.de> CommitterDate: Fri, 18 Nov 2022 22:10:12 +01:00 x86/microcode/intel: Use a reserved field for metasize Intel is using microcode file format for IFS test images too. IFS test images use one of the existing reserved fields in microcode header to indicate the size of the region in the file allocated for metadata structures. In preparation for this, rename first of the existing reserved fields in microcode header to metasize. In subsequent patches IFS specific code will make use of this field while parsing IFS images.
