From: Greg KH <[email protected]> 3.4-stable review patch. If anyone has any objections, please let me know.
------------------ From: Feng Tang <[email protected]> commit b7db60f45d74497c723dc7ae1370cf0b37dfb0d8 upstream. 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 <[email protected]> Cc: Thomas Renninger <[email protected]> Reviewed-by: Rafael J.
