Upgrade rt kernel patch to CentOS7.6 3.10.0-957.12.2

New set of CVEs was reported against Intel CPUs: CVE-2018-12126,
CVE-2018-12127, CVE-2018-12130 and CVE-2019-11091.
For these CVEs there are RH and CentOS updates available.

CVE-2018-12126:
Microarchitectural Store Buffer Data Sampling (MSBDS):
Store buffers on some microprocessors utilizing speculative
execution may allow an authenticated user to potentially
enable information disclosure via a side channel with local access.
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

CVE-2018-12127:
Microarchitectural Load Port Data Sampling (MLPDS):
Load ports on some microprocessors utilizing speculative execution
may allow an authenticated user to potentially enable information
disclosure via a side channel with local access. 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

CVE-2018-12130:
Microarchitectural Fill Buffer Data Sampling (MFBDS):
Fill buffers on some microprocessors utilizing speculative execution
may allow an authenticated user to potentially enable information
disclosure via a side channel with local access. 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

CVE-2019-11091:
Microarchitectural Data Sampling Uncacheable Memory(MDSUM):
Uncacheable memory on some microprocessors utilizing speculative
execution may allow an authenticated user to potentially enable
information disclosure via a side channel with local access.
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.
