Subject: [PATCH rcu 12/13] torture: Make torture.sh --allmodconfig testing fail on warnings

From: "Paul E. McKenney" <paulmck@...nel.org>

Currently, the torture.sh --allmodconfig testing looks solely at the
exit code from the kernel build, and thus fails to flag many compiler
warnings.  This commit therefore checks the kernel-build output for
compiler diagnostics.
