From 1cad5e9a3978d182aa9b0e909fb0379da5ba45af Mon Sep 17 00:00:00 2001 From: Toshi Kani Date: Thu, 29 Aug 2013 18:22:08 -0600 Subject: hotplug / x86: Disable ARCH_CPU_PROBE_RELEASE on x86 Commit d7c53c9e enabled ARCH_CPU_PROBE_RELEASE on x86 in order to serialize CPU online/offline operations. Although it is the config option to enable CPU hotplug test interfaces, probe & release, it is also the option to enable cpu_hotplug_driver_lock() as well. Therefore, this option had to be enabled on x86 with dummy arch_cpu_probe() and arch_cpu_release(). Since then, lock_device_hotplug() was introduced to serialize CPU online/offline & hotplug operations. Therefore, this config option is no longer required for the serialization. This patch disables this config option on x86 and revert the changes made by commit d7c53c9e. Signed-off-by: Toshi Kani Acked-by: Yasuaki Ishimatsu Signed-off-by: Rafael J.
