RISC-V Patches for 3.2, Part 3

This patch set contains a handful of patches I've collected over the
last few weeks.  There's nothing really fundamental, but I thought it
would be good to send these out now as there are some other patch sets
on the mailing list that are getting ready to go.

As far as the actual patches, there's:

* A set that cleans up our FS dirty-mode handling.
* Support for writing MISA.
* The removal of Michael as a maintainer.
* A fix to {m,s}counteren handling.

This passes my standard "boots Fedora" test case.

There is no 3.2 release; the next release is named 4.0.  However, if you
don't want to bother with sending a v2 pull request just to fix the
merge commit message, that's okay with me.

Ah, sorry.  I think I'm just going to leave it as is, I'll get it right next 
time.

Also note that you used "PR RFC" in the title ... so not sure whether
Peter's scripts will catch this PR as a valid one...

My mail filter finds these RFC pullrequests, yes. I'm then
relying on my manual brain to not actually apply them.
(If it's a slow day I might do a test merge on them, but
usually my queue is full enough that I don't get to them
before the real PR appears.)

It's actually meant not to: my blow is to send out these as a test to see if 
there's anything wrong, and then if there is to fix it up.  I'm less worried 
about the text of the pull request and more about making sure I didn't screw up 
a patch, which is the only reason I wasn't worried about picking up your 
suggested change.

Ah, OK -- do you want me to do something else?

At least I got a little bit confused by "PR RFC" ... I think some other
maintainers rather send out patch series marked with "PATCH" first, and
add some non-pull-request cover letter with a text like "I'm intending
to send a pull request for this soon, please review one more time...".
Then after a day or two, once Patchew checked the series and nobody else
complained, they send a real "PULL" request.
(at least that's how I saw the handling on the mailing list in the past,
not sure whether Peter has a different point of view here, though).

Yeah, generally nobody else sends RFC pull requests, they just
send the actual pulls. I don't object if Palmer finds them
useful, though.

For what it's worth, my filter for finding pull requests is emails
containing "for you to fetch changes up to" but not either of
"not for master" or "PULL SUBSYSTEM". So if you want to specifically
keep out of the filters you can add "not for master" in the cover
letter. But as I say it's not a big deal for me to sort things out
manually -- the filter has the odd false positive anyway.

If nobody else does it then I might stop -- they were more useful for me when I 
was new at this, as I was pretty worried about making mistakes and wanted to 
make sure I didn't screw anything up.  Things have gone pretty smoothly, so it 
might just have been paranoia.

Unless anyone likes these I think I'll stop sending them.

OK, makes sense.
