All three shares one issue.  Does the syntax offer you a way to give
enough information so that you can confidently say that it will find the
commit that touched the path most recently?  How is the "most recently"
defined?

At least you can restate the first one to:

    git revert $(git log -1 --pretty=format:"%h" core/softlockup -- kernel/softlockup.c)

to limit to "the one that touched this file _on this topic_".

The closest I can think of is

	git revert ':/the title of the commit'

but it shares the exact same issue of "how would I limit the search space
to make sure it finds the right commit".
