This patch implements real Xen acpi memory hotplug driver as module.
When loaded, it replaces Xen stub driver.
When an acpi memory device hotadd event occurs, it notifies OS and
invokes notification callback, adding related memory
to prevent this type of bug from reoccurring in the future.

Hey Jens,
Please git pull the following branch:

Anyhow, I think this patch makes sense - it makes sure that the
MSR value is sane.

Attached are two patches to the ACPI subsystem and the cpuidle drivers.
The fixes are to deal with the case when cpuidle_disabled returns true
and we try to hotplug CPUs on/off.

Also, since IOMMU drivers can no longer assume swiotlb is allocated
enough_mem_for_swiotlb() check fails, AMD IOMMU or another other iommu
driver can't simply rely on changing swiotlb=1 and assuming the buffer
is there.
As Konrad suggested, a hook is needed, however, I think the logic to

Konrad, are you OK with this patch now?
Yes, I wanted to make sure that the existing behavior under baremetal
was not altered.
And Duan had confirmed it was not - thought to be on a safe side it
would be good to confirm this via testing just in case.
