furthmore it cannot even trigger if you invlpg with an address page aligned (4mbyte aligned in this case) like we would always do in linux anyways, we never use invlpg on misaligned addresses, no matter if the page is a 4M or a 4k page. And I guess with PAE enabled it cannot
even trigger in first place (it speaks only about 4M pages, pae only provides 2M pages instead).
I think this is a very very minor issue, I doubt anybody ever triggered it in real life with linux.
# Ce problème n'existe pas (semblerait-il).

Alan Cox :
That problem shouldnt be hitting Linux x86. I don't know about the Nvidia module but the base kernel shouldnt hit an invlpg on 4Mb pages

Bon, faut les laisser bosser encore un peu mais ça semble être beaucoup de bruit pour rien.
