[RFC] two new linux-next trees (SPI and devicetree)

[Grant Likely <grant.likely@secretlab.ca>]

Hi Stephen,

I've got two trees that I'd like to have some linux-next exposure, but
I don't want to step on any toes...

First one is a bunch of SPI patches.  I've made the offer to be SPI
co-maintainer, but I haven't received any feedback yet from either
akpm or dbrownell.  In the mean time, I still have a bunch of SPI
patches (properly signed off and everything) that should have
linux-next exposure before the merge window.  I've put them in the
tree shown in the request-pull output below.

David, akpm, please note:  I'm not intending to ask Linus to pull this
tree, but I do really need some feedback on what you want me to do.
The tree should be properly formed and signed off, so I can ask Linus
to pull from me directly if you wish.

The second one is a bunch of the device tree changes that I want to
give some linux-next exposure as soon as possible.  The tree is
properly formed, but I haven't collected a full set of acks from all
the relevant folks.  Once I get all the acks, I merge the commits into
the next-devicetree branch that you're already pulling.  Ben in
particular is very busy and hasn't had time to review.  They are in
this tree:

  git://git.secretlab.ca/git/linux-2.6 test-devicetree

So, here's the RFC.  I'd *like* to get them into linux-next before
benh gets time to ack them; but there is possibly a greater likelyhood
of breakage.  Can you add them to the end of the queue and just punt
it out if they cause grief?  Do you have any other suggestions?
Should I just put them into next-devicetree and fix it up as I get
acks?  (BTW, I have at least compile tested this tree on 32/64 bit
powerpc, 32/64 bit sparc and microblaze).

Thanks,
g.
