I think you can remove this one from the regression list. I've received an
update from Florian that said !

According to #22652 "*ERROR* Attempting to mmap a purgeable buffer" warns about
a userspace error.

It links to ticket #22652 in which Chris Wilson indicates this is warning
about userspace bug, and that this issue is tracked in :
https://bugs.freedesktop.org/show_bug.cgi?id=31419

So, this definitely looks like the problem is not in the kernel (though my
personal view on this is that the message itself should be made much more
clear and reflect that the problem is not in the kernel, but in userspace).

Thanks for the tracking you've made,
Paul
