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.The build-logic-and-sources-for-TiC.patch version number
  has been modified.

3.In addition to the modifications in the files in 1 and 2,
  other patches only modify the line number.
