	panic_print=	Bitmask for printing system info when panic happens.

			User can chose combination of the following bits:

			bit 0: print all tasks info

			bit 1: print system memory info

			bit 2: print timer info

			bit 3: print locks info if CONFIG_LOCKDEP is on

			bit 4: print ftrace buffer

			bit 5: print all printk messages in buffer

			bit 6: print all CPUs backtrace (if available in the arch)

			Use this option carefully, maybe worth to setup a

			bigger log buffer with "log_buf_len" along with this.
