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.
