This only was a problem on sparc, and it no longer exists at all in 2.6.x kernels. It was too much of a pain to keep teaching people that violated this, and it resulted in some contorted code as well.
So don't worry about this at all in 2.6.x and later. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
