in_irqentry_text() which is called by filter_irq_stacks()\nuses __irqentry_text_start/end symbol to find irq entries in callstack.\n\nBut it doesn't work correctly as without \"CONFIG_FUNCTION_GRAPH_TRACER\",\narm64 kernel doesn't include gic_handle_irq which is entry point of arm64 irq\nbetween __irqentry_text_start and __irqentry_text_end as we discussed in below
