parisc: implement irq stacks - part 2 (v2)
This patch fixes few build issues which were introduced with the last irq stack patch, e.g. the combination of stack overflow check and irq stack. Furthermore we now do proper locking and change the irq bh handler to use the irq stack as well. In /proc/interrupts one now can monitor how huge the irq stack has grown and how often it was preferred over the kernel stack. IRQ stacks are now enabled by default just to make sure that we not overflow the kernel stack by accident. Signed-off-by: Helge Deller <deller@gmx.de>

If you say Y here the kernel will use separate kernel stacks
for handling hard and soft interrupts. This can help avoid
