I haven't thought through all the merging details yet, but do be aware
of the dependencies this patchset has:

1) Rename of arch/arm/mach-tegra/gpio.c -> drivers/gpio/gpio-tegra.c
   This is in Grant's gpio for-next branch, and hence linux-next.
   This is in some GPIO-related branch of Russell's.

2) Various previous Tegra <mach/gpio.h> rework.
   This is in some GPIO-related branch of Russell's; I assume the same one
   as (1), but I can't actually find this branch, so can't check.

Neither of those is in any Linus release or rc.

I *think* that's it.

For reference, this patchset was physical written/tested on top of
next-20110823, with the patches mentioned in (2) aboe, and some others that
hopefully aren't relevant, between linux-next and this patchset.
