As we now have generic infrastructure to support backtracing of other CPUs in the system on lockups, we can start to implement this for ARM. Initially, we add an IPI based implementation, as the GIC code needs modification to support the generation of FIQ IPIs, and not all ARM platforms have the ability to raise a FIQ in the non-secure world. This provides us with a "best efforts" implementation in the absence of FIQs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
