The function name of cpumask_clear_cpu was not correct. Reported-by: Jin Qing <b24...@freescale.com> Signed-off-by: Li Yang <le...@freescale.com> --- This also implies that the CONFIG_HOTPLUG_CPU was never tested. We are trying to add cpu hotplug for SMP suspend, but seeing the following error(on 2.6.31 with context patches applied). Any idea or suggestion?
