Still not perfect, but good enough for now. Patch is Tested-by: Christian König <christian.koe...@amd.com>.

I think you need to rework the VM walking a bit, cause we need to support the T bit as well in the future and your code make a few assumptions which doesn't allow that.

Doesn't the T bit imply V=0 which means the page isn't backed by memory.  Not much umr could do about that other than to print out the T bit.

No, the T bit means translate further. In other words it is the counter part of the P bit and means that a PTE should be handled as a PDE.

But for this to have meaning you also need to handle the fragment size as well (Now I have you totally confused, haven't I? :).

Cheers,
Christian.
