The probe function of the pio platform driver lives in the init section
and so a pio device that is created after the init section is discarded
probably results in an oops. Even if this cannot happen, using
platform_driver_probe is cleaner. (If this can happen and should be
supported the probe function must live in the devinit section instead.)

Currently, setting up the portmux is completely one-shot: Once a pin is
muxed, the portmux driver will complain loudly and refuse to do anything
if you try to set up the same pin again.
Sometimes, it may be necessary to change the configuration of a pin
after it has been set up initially. This patch adds a way to undo the
previous configuration, allowing the pin to be reconfigured.

The NGW100 board has jumper J15 (near the reset button) which
is unused. This patch exports it through the GPIO sysfs support
(as /sys/class/gpio/gpio62/value) so that it's easily queried
by boot scripts or whatever might want to know if the jumper
has been installed (value = 0) or not (value = 1, "default").

This patch adds backtracing capability to oprofile profiling in kernel
and user mode on AVR32. This is done by going through the frames on the
stack and adding oprofile traces for all return addresses. The code
being profiled has to be compiled with frame pointers to make this work.

This patch adds a UUID to the GFS2 sb structure. This field is not
actually referenced from kernel space at all, but is added for
completeness and due to the userland tools which get their on-disk
structure information from the gfs2_ondisk.h header file.
Since we have to be backwards compatible, we will assume that any GFS2
sb for which the UUID is all 0 does not have a UUID as such.
We should then be (after some userland changes) able to support the -U
mount option. This addresses Fedora bugzilla #242689

The nr_conns variable in the sync message header is only eight bits wide
and will overflow on interfaces with a large MTU. As a result the backup
won't parse all connections contained in the sync buffer. On regular
ethernet with an MTU of 1500 this isn't a problem, because we can't
overflow the value, but consider jumbo frames being used on a cross-over
connection between both directors.
We now restrict the size of the sync buffer, so that we never put more
than 255 connections into a single sync buffer.

This adds support for OLPC's touchpad. It has lots of neat features,
none of which are enabled because the hardware is too buggy. Instead,
we use it like a normal touchpad, but with a number of workarounds in
place to deal with the frequent hardware spasms. Humidity changes,
sweat, tinfoil underwear, plugging in AC, drinks, evil felines.. All
tend to cause the touchpad to freak out.

psmouse_queue_work is passed a delayed_work struct, and queues up the work

This patch adds support for a low(er)-power suspend-to-RAM.
In addition to the SDRAM being put into self-refresh mode, the Master
Clock is set to the Slow-clock rate (32Khz) and PLLA & PLLB are
disabled.
Certain peripherals are therefore also disabled, and thus cannot be
used as wakeup sources.
This patch has been included in the AT91 patches in various forms
since 2.6.19 and a number of people have worked or commented on it,
most notably:

Anti Sullin (for the SAM9260 version)
