Zhang, Yanmin 4f167fb491 [PATCH] spurious interrupt fix 
On my IA64 machine, after kernel 2.6.12-rc3 boots, an edge-triggered
interrupt (IRQ 46) keeps triggered over and over again.  There is no IRQ 46
interrupt action handler.  It has lots of impact on performance.

Kernel 2.6.10 and its prior versions have no the problem.  Basically,
kernel 2.6.10 will mask the spurious edge interrupt if the interrupt is
triggered for the second time and its status includes
IRQ_DISABLE|IRQ_PENDING.

Originally, IA64 kernel has its own specific _irq_desc definitions in file
arch/ia64/kernel/irq.c.  The definition initiates _irq_desc[irq].status to
IRQ_DISABLE.  Since kernel 2.6.11, it was moved to architecture independent
codes, i.e.  kernel/irq/handle.c, but kernel/irq/handle.c initiates
_irq_desc[irq].status to 0 instead of IRQ_DISABLE.
