    parisc: implement irq stacks - part 2 (v2) · 416821d3
    Helge Deller authored
    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.
