Created attachment 83824 [details] Tarball of patches Andrew Cooper has implemented a bunch more Xen hypercalls and fixed a few bugs in some existing ones, meaning that Valgrind can now successfully monitor a Xen save/restore/migrate. I also added support for XEN_DOMCTL_set_max_evtchn which is a new one in Xen 4.4. There are fourteen patches in all, rather than attach them individually I have attached a tarball. I hope that is OK.
The attached patches have been committed as r13725..r13738 on the trunk.
