[PATCH 0/3, v3] feat: checkpatch: warn about dicouraged link tags and missing links

[Kai Wasserbäch]

Hey,
Thorsten Leemhuis suggested the following two changes to checkpatch, which
I hereby humbly submit for review. Please let me know if any changes
would be required for acceptance.

The third patch came out of the preview rounds and fixes an odd
behaviour noticed then.

The two main changes should help developers write commit messages in a way
that's preferred by Linus and will greatly help Thorsten's regression
tracking efforts.

Patches are against mm/mm-nonmm-stable (which apparently is the tree
checkpatch changes are merged through).

Cheers,
Kai


v2->v3:
- address review feedback from Joe (grammer fixes, use of $herecurr, use
of --no-merges in commit log quote) (Thorsten)
- warn when people try to add version information to the commit log
using code suggested by Joe (Thorsten)
- add a patch to make existing code in a nearby area use $herecurr where
it should, which Joe noticed during review

v1->v2:
- add commit messages explaining the reasoning (Thorsten)
- approach the usage of wrong tags with an allow list as suggested by
Joe (Thorsten)
