powerpc/powernv: Machine check and other system interrupts
OPAL can handle various interrupt for us such as Machine Checks (it performs all sorts of recovery tasks and passes back control to us with informations about the error), Hardware Management Interrupts and Softpatch interrupts. This wires up the mechanisms and prints out specific informations returned by HAL when a machine check occurs. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
