[PARISC] Fix our interrupts not to use smp_call_function
Fix our interrupts not to use smp_call_function On K and D class smp, the generic code calls this under an irq spinlock, which causes the WARN_ON() message in smp_call_function() (and is also illegal because it could deadlock). The fix is to use a new scheme based on the IPI_NOP. Signed-off-by: James Bottomley <jejb@parisc-linux.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org>
