Yeah, the Thumb2 code is not supported by Ben Dooks patches, it's part
of the TODO-list. I think Ben said he would probably not have much time
to work on this. I might be able to spare some time on this, so just
let me know if I should start working on this. If I remember correctly,
it's mainly the fixup_pv_table code that needed some Thumb2/BE love.

Will, is getting Thumb2 working a requirement to get the BE support
merged, or can we for now make the BE option depends on !THUMB2_KERNEL ?
