    Subject[PATCH v2 24/31] arm64: Add support for /proc/sys/debug/exception-trace
    Date
    This patch allows setting of the show_unhandled_signals variable via
    /proc/sys/debug/exception-trace. The default value is currently 1
    showing unhandled user faults (undefined instructions, data aborts) and
    invalid signal stack frames.
