[ Upstream commit 4bbcbc6ea2fa379632a24c14cfb47aa603816ac6 ]
For small bitmaps that aren't PAGE_SIZE aligned *and* that are less than
512 pages in bitmap length, use an extra page to be able to cover the
entire range e.g. [1M..3G] which would be iterated more efficiently in a
single iteration, rather than two.
