From b7db60f45d74497c723dc7ae1370cf0b37dfb0d8 Mon Sep 17 00:00:00 2001 From: Feng Tang Date: Tue, 31 Jul 2012 12:44:43 +0800 Subject: [PATCH] ACPI processor: Fix tick_broadcast_mask online/offline regression In commit 99b725084 "ACPI processor hotplug: Delay acpi_processor_start() call for hotplugged cores", acpi_processor_hotplug(pr) was wrongly replaced by acpi_processor_cst_has_changed() inside the acpi_cpu_soft_notify(). This patch will restore it back, fixing the tick_broadcast_mask regression: https://lkml.org/lkml/2012/7/30/169 Signed-off-by: Feng Tang Cc: Thomas Renninger Cc: # 3.3+ Reviewed-by: Rafael J.
