This series is *very* RFC at the moment - it is only compile tested. I would very much appreciate review on the design. (and I shall see about sorting out some dev testing tomorrow) The ultimate purpose is to fix that the fact that XEN_DOMCTL_gethvmcontext_partial is very unreliable at providing the correct subset of information. All the changes are supposed to be internal to Xen. There should be no difference at all to the result of XEN_DOMCTL_gethvmcontext (which can be used as a useful dev test for the validity of the changes). George: As for whether this is intended for 4.5, I have no idea. On the one hand, it is fixing a hypercall which doesn't function correctly, but on the other hand, it is a very large and complicated set of changes relevant to migration. Then again, the majority of the changes were largely mechanical, and there is a simple test to prove whether there are bugs or not. I shall defer to others for comments on the risk/rewards of this series.
