[Xen-devel] Re: invalid PTE for xen_start-info ?
Keir Fraser wrote:
You should use pte_pfn(), or pte_mfn(), or (pte_val() & PHYSICAL_PAGE_MASK)
for isolating the address part of a pte. If there is *any* Linux code that
is accessing addresses from pte contents via other methods then please do
let us know! But I suspect this won't be the case, due to the existing need
to mask off PAGE_NX.
Does that break compatibility between the hypervisor and
older guests?
