> Since the hypervisor always uses 4K as its page size, the size of PFNs
> used for gpadl should be HV_HYP_PAGE_SIZE rather than PAGE_SIZE, so
> adjust this accordingly as the preparation for supporting 16K/64K page
> size guests. No functional changes on x86, since PAGE_SIZE is always 4k
> (equals to HV_HYP_PAGE_SIZE).
