Re: [Xen-devel] Hypercall interface changes for PAE

The downside of this approach is that the C declarations of mmu_update_t, update_va_mapping, etc are different on 32-bit PAE builds. But only low-level guest code will touch those interfaces anyway, and there is unlikely to be code sharing between PAE and non-PAE at that level.

What do you think?

Actually, we could export intpte_t and physaddr_t at the guest interface and declare mmu_update_t and friends in terms of those typedefs. This would also avoid needing different wrapper implementations of those hypercalls within Xen itself. Neat. :-)
