This means that interrupts get enabled in the middle of context_switch() while switching to new tasks that get forked off the init task during boot. Don't do this.

CRISv32 has no working SMP, so spinlocks becomes a NOP, so deadlock was never seen.

It's a NOOP since 2.6.35 and it will be removed one day. Comments mentioning IRQF_DISABLED are also updated, knowing that all interrupts are now "fast interrupts", their handlers running with interrupts disabled. Don't hesitate to let me know if you have other ways of rephrasing the comments!

I decided not to delete the arch-v*/Kbuild files as it's possibly someone might want to use them for genhdr-y lines in the future, but they could be deleted and the pointer lines removed from asm/Kbuild. The uapi/arch-v*/Kbuild files ought to be uneffected by such a change. asm/swab.h didn't have anything outside of __KERNEL__ so nothing appeared in uapi/asm/swab.h. The latter, however, is exported by Kbuild.asm. This needs to be applied after the CRIS UAPI disintegration patch.
