    panic: Make panic_timeout configurable · 5800dc3c
    Jason Baron authored
    The panic_timeout value can be set via the command line option
    'panic=x', or via /proc/sys/kernel/panic, however that is not
    sufficient when the panic occurs before we are able to set up
    these values. Thus, add a CONFIG_PANIC_TIMEOUT so that we can
    set the desired value from the .config.
    
    The default panic_timeout value continues to be 0 - wait
    forever. Also adds set_arch_panic_timeout(new_timeout,
    arch_default_timeout), which is intended to be used by arches in
    arch_setup(). The idea being that the new_timeout is only set if
    the user hasn't changed from the arch_default_timeout.
