    softlockup: allow panic on lockup · 9c44bc03
    Ingo Molnar authored
    allow users to configure the softlockup detector to generate a panic
    instead of a warning message.
    
    high-availability systems might opt for this strict method (combined
    with panic_timeout= boot option/sysctl), instead of generating
    softlockup warnings ad infinitum.
    
    also, automated tests work better if the system reboots reliably (into
    a safe kernel) in case of a lockup.
    
    The full spectrum of configurability is supported: boot option, sysctl
    option and Kconfig option.
    
    it's default-disabled.
