2013-03-11xen/acpi: remove redundant acpi/acpi_drivers.h includeLiu Jinsong
It's redundant since linux/acpi.h has include it when CONFIG_ACPI enabled, and when CONFIG_ACPI disabled it will trigger compiling warning In file included from drivers/xen/xen-stub.c:28:0: include/acpi/acpi_drivers.h:103:31: warning: 'struct acpi_device' declared inside parameter list [enabled by default] include/acpi/acpi_drivers.h:103:31: warning: its scope is only this definition or declaration, which is probably not what you want [enabled by default] include/acpi/acpi_drivers.h:107:43: warning: 'struct acpi_pci_root' declared inside parameter list [enabled by default] Reported-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Liu Jinsong <jinsong.liu@intel.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>

Add Xen stub driver for CPU hotplug, early occupy to block native, will be replaced later by real Xen processor driver module. Signed-off-by: Liu Jinsong <jinsong.liu@intel.com> Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2013-02-19xen/stub: driver for memory hotplugLiu Jinsong
This patch create a file (xen-stub.c) for Xen stub drivers. Xen stub drivers are used to reserve space for Xen drivers, i.e. memory hotplug and cpu hotplug, and to block native drivers loaded, so that real Xen drivers can be modular and loaded on demand. This patch is specific for Xen memory hotplug (other Xen logic can add stub drivers on their own). The xen stub driver will occupied earlier via subsys_initcall (than native memory hotplug driver via module_init and so blocking native). Later real Xen memory hotplug logic will unregister the stub driver and register itself to take effect on demand.
