A list of impacted products can be found here: https://www.intel.com/content/dam/www/public/us/en/documents/ corporate-information/SA00233-microcode-update-guidance_05132019.pdf These are from the http://cve.mitre.org website. These are the MDS security CVEs. The patch is modified as follows: 1.Delete the 929-931 line of the arch/x86/kernel/cpu/cacheinfo.c file, because starlingx's Porting-Cacheinfo-from-Kernel-4.10.17.patch removes the ici_cpuid4_info structure. 2.Except for the modification of the file in 1, the other patches only modify the line number.
