Yeah, if Petr is fine with that then I'm OK. But at the same time,
we have `panic_print' which is a bit mask of what panic_print_sys_info()
should do. And now we also have a boolean `console_flush` flag that tells
panic_print_sys_info() to ignore some (one as of now) bits of `panic_print'.

So _maybe_ panic_print_sys_info() can just accept panic_print as
its parameter and then we can do something like this (as an example)

	panic_print_sys_info(panic_print & ~PANIC_PRINT_ALL_PRINTK_MSG);

Merely because `panic_print_sys_info(false);` doesn't tell much to a reader.
Like what is print sys info false?

Or did you already discuss this?
