Except that powerpc (and now it seems x86) both want to use radix trees for interrupt handling... At least on powerpc, we trick and use a linear search until the radix trees are initialized, which we do later during boot, but that somewhat sucks.
I believe sherry picking things like not calling radix_tree_init() is going to fix one case today, until we have another one, and another one, and etc...
I suspect we're better off fixing the root of the problem in down/up.
Cheers, Ben.
