32-bit, PAE and RAM above 4GB seems to be enough to trigger that bug.

Bum. We established that once you fix the accessors+sign extension bug, there's another bug somewhere later on in the series. Any chance you could move "x86/pgtable: fix constant sign extension problem" to be just after "x86/pgtable: unify pagetable accessors" and bisect the following patches?

Thanks,
