From mboxrd@z Thu Jan 1 00:00:00 1970 From: mturquette@ti.com (Mike Turquette) Date: Tue, 19 Jul 2011 16:47:11 -0700 Subject: [PATCH 2/2] OMAP4: Kconfig: remove hotplug control for CPU0 Message-ID: To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
