As we always allocate in chunks of 4096 (that being both the PAGE_SIZE and our own GTT_PAGE_SIZE), we know that all results from the drm_mm are aligned to at least 4096. The drm_mm allocator itself is optimised for alignment == 0, and so by converting alignments of 4096 to 0 we can satisfy our own requirements and still hit the faster path.
