arm64: implement exception depth count Add the exception depth count to tpidrro_el0 and make it available through the arch_exception_depth() accessor. The IN_EL0 flag is now updated unconditionally even if userspace is not configured. Doing otherwise made the code rather hairy and I doubt the overhead is measurable.
