Hopefully that should be ok. In fact we use the radix tree in our
interrupt handling and today we have a horrible hack that reverts
to linear search early during boot until we can allocate the radix
trees in an arch_initcall.

Thus the patch should allow us to simplify that code and remove
that late init hack.

Cheers,
Ben.
