[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH][1/2] pvops-dom0: Xen acpi processor logic cleanup
Base on git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git branch:
xen/dom0/acpi-parser
====
Xen acpi processor logic cleanup
From: Yu Ke <ke.yu@xxxxxxxxx>
current xen acpi processor logic scattered in several places and mixed with
other acpi_processor_driver logic. this patch try to split these logic out and
consolidate them into a new xen acpi_processor_driver. this will make xen acpi
processor logic more clean
