Subject: [PATCH tip/core/rcu 3/9] rcutorture: Remove CONFIG_HOTPLUG_CPU=n from scenarios
Date: Wed,  2 Oct 2019 18:47:22 -0700
Message-ID: <20191003014728.13496-3-paulmck@kernel.org> (raw)
In-Reply-To: <20191003014710.GA13323@paulmck-ThinkPad-P72>

From: "Paul E. McKenney" <paulmck@linux.ibm.com>

A number of mainstream CPU families are no longer capable of building
kernels having CONFIG_SMP=y and CONFIG_HOTPLUG_CPU=n, so this commit
removes this combination from the rcutorture scenarios having it.
People wishing to try out this combination may still do so using the
"--kconfig CONFIG_HOTPLUG_CPU=n CONFIG_SUSPEND=n CONFIG_HIBERNATION=n"
argument to the tools/testing/selftests/rcutorture/bin/kvm.sh script
that is used to run rcutorture.
