Hi Olof,

I just sent a patch series that addresses your comments:

	[PATCH 00/12] Add NVIDIA Tegra FUSE driver

That contains a lot of the cleanup that I've been doing to get things
ready for 64-bit. It's essentially what this pull request contained,
with a couple of other patches on top to untangle the init sequence
so that these can all go into regular init calls. I've tested on all
four Tegra generations supported upstream.

While there's possibly more that we can do I think it is a reasonable
first step and I'd like to get this into 3.17 so that we can start
moving out other things after the merge window.

It would be great if you could have a look, and if there aren't any
objections I'll send out another pull request.

Thierry
