Subject: [PATCH 4.14 34/54] arm64: Disable unhandled signal log messages by default
Date: Mon, 26 Feb 2018 21:22:11 +0100 [thread overview]
Message-ID: <20180226202146.085107460@linuxfoundation.org> (raw)
In-Reply-To: <20180226202144.375869933@linuxfoundation.org>
4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Michael Weiser <michael.weiser@gmx.de>
commit 5ee39a71fd89ab7240c5339d04161c44a8e03269 upstream.
aarch64 unhandled signal kernel messages are very verbose, suggesting
them to be more of a debugging aid:
sigsegv[33]: unhandled level 2 translation fault (11) at 0x00000000, esr
0x92000046, in sigsegv[400000+71000]

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