Virtual address need to be fenced to know when we can safely remove it. This patch also properly clear the pagetable. Previously it was serouisly broken.
v2: For to update pagetable when unbinding bo (don't bailout if bo_va->valid is true).
This version is for stable 3.5 only.
Why?
Because 3.4 needs again a different patch and 3.6 needs a different patch. Code around this patch changed btw 3.4-3.5 and changed again btw 3.5-3.6 and in non trivial way.
Then please say that in the original patch, and point to where the changes happened, and resend it so that I can apply it.
I also need an ack from the maintainer(s) that this is acceptable.
greg k-h
I resend the original patch with comment that says 3.5 need special patch.
Cheers, Jerome
