[PATCH] ppc64: fix IPI on bpa_iic
This fixes a severe bug in the bpa_iic driver that caused
all sorts of problems.
We had been using incorrect priority values for inter processor
interrupts, which resulted in always doing CALL_FUNCTION
instead of RESCHEDULE or DEBUGGER_BREAK.
The symptoms cured by this patch include bad performance on
SMP systems spurious kernel panics in the IPI code.
