These 3 patches are basically a completion of the initial approach I suggested in that earlier thread: https://lkml.kernel.org/r/20190320221534.165ab87b@oasis.local.home Yes, idtentry is a mess, and this doesn't help, but lets fix this now before someone else trips over it. This boots on x86_64 and builds on i386 so it must be perfect. No Xen testing what so ever, because I wouldn't know where to begin.
