+cc linux-mm since I'm struggling to know how bad is this issue and
if this should be picked for 6.1-rc8 or not.

I tested this fix on an Ubuntu kernel in sv39 mode without any issue
but the version without the fix seems to work fine too, either this is
not a real issue or I don't exercise the right thing to make it visible.

Any help appreciated!
