Re: [Xen-devel] page table walk in xen_{create, destroy}_contiguous_region

Is there a particular reason why these functions need to walk the page table rather than doing a much cheaper p2m translation? vstart is assumed to be in the direct mapping area anyway (otherwise the uses of __pa() in the same

Thanks, Jan

Looks like the walks are not really needed.
