[PATCH tip/core/rcu 05/26] rcuscale: Allow CPU hotplug to be enabled

From: Paul E. McKenney
Date: Tue May 11 2021 - 19:12:40 EST


It is no longer possible to disable CPU hotplug in many configurations,
which means that the CONFIG_HOTPLUG_CPU=n lines in rcuscale's Kconfig
options are just a source of useless diagnostics. In addition, rcuscale
doesn't do CPU-hotplug operations in any case. This commit therefore
changes these lines to read CONFIG_HOTPLUG_CPU=y.
