From: Ard Biesheuvel <[email protected]> The memblock API guarantees that start is not greater than or equal to end, so there is no need to test it. And if were, it is doubtful that breaking out of the loop would be a reasonable course of action here (rather than attempting to map the remaining regions)
So let's drop this check.
