Subject: [PATCH 111/242] x86/cpufeatures: Fix various details in the feature
definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
CVE-2017-5754
Kept this commit separate from the re-tabulation changes, to make
the changes easier to review:
- add better explanation for entries with no explanation
- fix/enhance the text of some of the entries
- fix the vertical alignment of some of the feature number definitions
- fix inconsistent capitalization
- ... and lots of other small details
i.e. make it all more of a coherent unit, instead of a patchwork of years of additions.
