The bounce buffer, used for misaligned bytes for ADMA access,
resides wholly within the (align_sz)-aligned word, just by construction.
The page addresses are aligned to (align_sz), either for 4 or 8 bytes
alignment, so that the aligned word resides wholly within a single page
and can't cross the page boundary. So, the bounce buffer can't cross
the page boundary too. That's why the warnings are never hit, and can
be safely removed.
