Proposal: HAVE_SEPARATE_IRQ_STACK?

Hi folks, I do some ECC crypto in a kthread. A fast 32bit implementation usually uses around 2k - 3k bytes of stack. Since kernel threads get 8k, I figured this would be okay. And for the most part, it is. However, everything falls apart on architectures like MIPS, which do not use a separate irq

Move IRQ free code so that it will happen regardless of the __E1000_DOWN bit. Currently the e1000e driver only releases its IRQ if the __E1000_DOWN bit is cleared. This is not sufficient because it is possible for __E1000_DOWN to be set without releasing the IRQ. In such a situation, we will hit a
