Subject: [PATCH v1 0/2] x86/bugs: Exclude Zhaoxin family 7 CPUs

New Zhaoxin family 7 CPUs are not affected by SPECTRE_V2, SWAPGS.

Extend cpu_vuln_whitelist flag with a NO_SPECTRE_V2 bit. And add
these CPUs to the cpu vulnerability whitelist.

Tony W Wang-oc (2):
  x86/speculation/spectre_v2: Exclude Zhaoxin CPUs from SPECTRE_V2
  x86/speculation/swapgs: Exclude Zhaoxin CPUs from SWAPGS
