What's the symptom of this? A failing test? Or is this just a pro-activ fix?
if size < PAGE_SIZE then we would allocate 0, and in general we are
rounding down instead of up, which is obviously wrong.
I know, but is this fixing a failing test or is this just a pro-activ fix?
It is not fixing an existing test but it must be fixed before the VIRTIO
test that I am currently developing.
In the current tests we do not allocate sizes greater than 1 page that
are no multiple of pages.
