Yes, I now. I added IRQ_FORCED_THREADING to Kconfig. My hardware requires additional changes at arch/sparc and it's in a process of porting on 3.10 so I can't say if everything works on sparc or not yet. The other required fix to make sparc64 compilable is deletion of rwsem leftovers. I sent it to mainline sparc: https://git.kernel.org/cgit/linux/kernel/git/davem/sparc.git/commit/arch/sparc?id=61d9b9355b0d427bd1e732bd54628ff9103e496f It seems it's resonable to add it to the patch too.
