Subject: [PATCH] arm64: Add support for /proc/sys/debug/exception-trace

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.
