I know there are several ways to represent the same address using

Thanks a million.

Move PAGE_SHIFT to memmap.h
Xen: Use PAGE_SHIFT as a constant
Xen: Support
PAGE_SHIFT is used by both Virtio and Xen as a contant when moving
addresses from guest space to machine space, in order to have a
single definition PAGE_SHIFT has been moved to memmap.h. This has
no impact on neither virtio or xen.
