Michael Weiser 56b57bd20f arm64: Disable unhandled signal log messages by default
commit 5ee39a71fd89ab7240c5339d04161c44a8e03269 upstream.

aarch64 unhandled signal kernel messages are very verbose, suggesting
them to be more of a debugging aid:

Disable them by default, so they can be enabled using
/proc/sys/debug/exception-trace.
