This patch is a requirement to make Xen Memory access working on ARM. Could you reconsider the possibility to apply this patch on Xen? For the main concern of this thread (i.e the buggy scratch pfn with xc_dom_gnttab_hvm_seed), I wrote a patch to let the architecture decided which scrach pfn should be used. I will send the patch next week. Regards, -- Julien Grall
