Subject: [PATCH v2 0/2] x86/speculation: Fix incorrect MDS/TAA mitigation status

 v2:
  - Update the documentation files accordingly
  - Add an optional second patch to defer printing of MDS mitigation.

As MDS and TAA mitigations can be inter-related, setting command
line option for one without a matching other may cause one of their
vulnerabilities files to report their status incorrectly. This patch
makes sure that both vulnerabilities files will report consistent
status correctly.
