[RFC] Second OLPC Viafb series

[Jonathan Corbet <corbet@lwn.net>]

So this is the second series of viafb patches - the stuff that I was really
working toward since the beginning.  They depend on the previously-posted
first series.  What's added here is a big refactoring of the driver to
split its functions apart and the addition of code for GPIO, interrupt,
DMA, and camera management.

Florian, I incorporated your indexed port I/O patch, since it was an
obvious improvement and I was reworking that stuff anyway.

Note that the camera driver (the last in the series) is not yet ready for
submission; I add it here for completeness.

The full series of patches can be pulled from:

	git://git.lwn.net/linux-2.6.git viafb-posted

Some of this stuff is disruptive, and I only have one machine to test it
all on, so I'd really appreciate it if folks with other types of hardware
could try them out.
