| Subject | [PATCH 04/19] x86/dumpstack: make printk_stack_address() more generally useful |

Change printk_stack_address() to be useful when called by an unwinder
outside the context of dump_trace().
Specifically:
- printk_stack_address()'s 'data' argument is always used as the log
level string. Make that explicit.
- Call touch_nmi_watchdog().
