Subject: [PATCH 2/2] OMAP4: Kconfig: remove hotplug control for CPU0
Date: Tue, 19 Jul 2011 16:47:11 -0700 [thread overview]
Message-ID: <mailman.27.1311286727.20020.linux-arm-kernel@lists.infradead.org> (raw)
On OMAP4, CPU0 cannot be dynamically offlined through the usual CPU
hotplug mechanism due to a variety of constraints. It is treated as a
special "master" CPU for these reasons.
Select HOTPLUG_CPU_MASTER to prevent creation of the hotplug control
entry in sysfs.
