Has anyone else noticed that CR3 in oopses is now basically a lie with PTI? It shows CR3 at the time of the printing of the oops, not at the time of the fault like the normal registers. That greatly limits its usefulness in the dumps with PTI.
Should we carve out some space somewhere to stash it at entry so we can dump it in oopses? Any preferences on where? We need somewhere to write that's before the SWITCH_TO_KERNEL_CR3, most likely so cpu_entry_area is a candidate. The trampoline stack should also have space.
