James Morse 8e23dacd12 arm64: Add do_softirq_own_stack() and enable irq_stacks ... entry.S is modified to switch to the per_cpu irq_stack during el{0,1}_irq. irq_count is used to detect recursive interrupts on the irq_stack, it is updated late by do_softirq_own_stack(), when called on the irq_stack, before __do_softirq() re-enables interrupts to process softirqs. do_softirq_own_stack() is added by this patch, but does not yet switch stack. This patch adds the dummy stack frame and data needed by the previous stack tracing patches.
