If (start + size) is not cacheline aligned and (start & mask) > (end & mask), the last but one cacheline won't be invalidated as it should. Fix this by rounding `end' down to the nearest cacheline boundary if it gets adjusted due to misalignment. Also flush the write buffer unconditionally -- if the dcache wrote back a line just before we invalidated it, the dirty data may be sitting in the write buffer waiting to corrupt our buffer later.
