Linux 3.4-rc1

[Linus Torvalds]

Ok, it's been two weeks, and the merge window is over. Linux 3.4-rc1
has been pushed out to the git servers, and the tar-ball and patches
are going out as I type this (probably done by the time I'm done).

And yes, if you actually counted, it has only been 13 days. And if
somebody delayed their pull request until the last day of the merge
window, I'm sure they'll be even happier to delay it another two
months until the next merge window. Yay!

That said, there are four pull requests in my mailbox that weren't
delayed, and that I will (probably) still pull, but that I wanted to
get extra confirmation from *other* maintainers from first. So they
were sent in time, I just decided that I can make the actual pull
choice a bit later.

The four remaining pull requests (and the people I want comments from) are:

 - HSI (High Speed Synchronous Serial Interface) framework. I'm
planning on pulling this into 3.4, it's in my queue, but I wanted to
bring it up one more time in case somebody has issues with it. Ping?

 - pohmelfs. The old pohmelfs got deleted from staging, there's an
all-new one waiting in the sidelines. Al was a bit unhappy about some
of it, Evgeniy fixed it up some, and then the discussion died. Again,
I'm likely to pull this, but I wanted more commentary on it.

 - drm dma-buf prime support. Dave Airlie sent me the pull request but
didn't push very hard for it, it's in my "ok, I can still pull it for
3.4 if individual DRM driver people tell me that it will make their
lives easier." So this is in limbo - I have nothing against it, but I
won't pull unless I get a few people say "yes, please".

 - DMA-mapping framework. The tree now has a few more acks from
people, and it's largely in the same situation as HSI is: I'll
probably pull, but I really wanted the users who are impacted to
actually talk to me about it.

And that's it. So there's four more pulls pending, and likely, but
other than that we're done (unless you can show that you actually did
email me, but because of some cosmic mistake - probably involving my
incompetence - I've overlooked it. Hey, it happens).

Anyway, enough about the "what's still possibly pending". If you want
to see what actually went in, one fairly readable approach is to do
this:

    git log --merges --author=Torvalds v3.3..

because I really tried pretty hard to make readable merge messages if
I got any information at all from the submaintainer. And a lot of you
did send that in - thanks.  I've tried to distill most of that into
the appended "shortmerge" format (which is just me grepping for my
one-liner "pull what from whom" details).

One thing worth pointing out is that the header file cleanups were
nice, but let's never do them again. Or at least not for a release or
two. They caused a lot of merge conflicts and small annoyances, and
while I'm ok with resolving merges, it was annoying enough that I
don't want to go through that immediately again. I know they also
annoyed some submaintainers that were complaining to me about the
pain.

That said, I do think they helped. The <asm/system.h> disintegration
(and to a smaller degree the bug.h cleanups) may have been painful,
but it definitely cleaned things up. So I guess we *will* do things
like this in the future again, I just want to forget about the pain
before we embark on this next time. Ok?

Anyway, please do test and report any regressions.

                                    Linus
