Can you make that:
setup_clear_cpu_cap(X86_FEATURE_PGE);
and see if it fixes your issue?
Hmm, in reading the thread a bit more, that might not work. If I see it
correctly, lguest does
clear_cpu_cap(&boot_cpu_data, X86_FEATURE_PGE);
after the alternatives have run and static_cpu_has() sites have already
been patched so clearing that bit won't bring anything.
Yeah, I just tried that out and it had no effect unfortunately, the
static_cpu_has() was still 1.
