Like in this case sometime when I say x86 I mean x86_32, for clarity
x86_64 has never been affected by this, regardless of the .config.

common code bug (which is the most important thing!). I think it's a
bug in set_pmd_at when paravirt is set and PSA is off. If I'm right 4m
pages with PSA off should also work when disabling paravirt.

You said PSA and I kept saying it but I think we both meant
PAE. There's PSE and PAE, PSA is mix ;).

Reproduced and fix posted in the other mail with lkml on CC. Hope it
works!

Thanks,
Andrea
