Christoph Hellwig said runs sparse: 1) page_tables.c unnecessary initialization 2) Change prototype of run_lguest and do cast in caller instead (when we add __user to cast, it runs over another line). Al Viro pointed out the ugly cast in push_lguest_stack(): 3) Stick with unsigned long for arg, removes 4 casts in total. Most importantly, I now realize that Christoph's incorrect ranting

Impact: potential bugfix In theory, the kernel could reuse the same page as pgdir for a new process while the hypervisor keeps it cached. This would have undesirable results.

Because of legacy-induced blindness, I insisted on separately building the hypervisor.S switcher code (which is mapped at 0xFFC0000 in host and guest). However, the lguest64 patches showed the error of my ways: it has no relocations, so it can be linked into the module like normal then remapped. The only downside is that we can no longer use sizeof(hypervisor_blob), so we need to allocate our
