  KVM: x86: fix return value for reserved EFER (2019-05-24 21:55:02 +0200)

----------------------------------------------------------------
The usual smattering of fixes and tunings that came in too late for the
merge window, but should not wait four months before they appear in
a release.  I also travelled a bit more than usual in the first part
of May, which didn't help with picking up patches and reports promptly.

This says it's a tag, but it's not. It's just a commit pointer (also
called a "lightweight tag", because while it technically is exactly
the same thing as a branch, it's obviously in the tag namespace and
git will _treat_ it like a tag).

Normally your tags are proper signed tags. So I'm not pulling this,
waiting for confirmation.

Shell history shows that I typed

	git push kvm +HEAD:tags/for-linus

(which matches the "git push kvm +HEAD:queue" that I often do, and
therefore can be explained by muscle memory).

The interesting thing is that not only git will treat lightweight tags
like, well, tags: in addition, because I _locally_ had a tag object that
pointed to the same commit and had the same name, git-request-pull
included my local tag's message in its output!  I wonder if this could
be considered a bug.

I have now pushed the actual tag object to the same place.

Yeah, that's very much by design - lightweight tags are very
comvenient for local temporary stuff where you don't want signing etc
(think automated test infrastructure, or just local reminders).

Yeah, I think git request-pull should at least *warn* about the tag
not being the same object locally as in the remote you're asking me to
pull.

Are you sure you didn't get a warning, and just missed it? But adding
Junio and the Git list just as a possible heads-up for this in case
git request-pull really only compares the object the tag points to,
rather than the SHA1 of the tag itself.
