grub_mm_region_init() does: h = (grub_mm_header_t) (r + 1); where h is a grub_mm_header_t and r is a grub_mm_region_t. Cells are supposed to be GRUB_MM_ALIGN aligned, but while grub_mm_dump ensures this vs the region header, grub_mm_region_init() does not. It's better to be explicit than implicit here: rather than changing grub_mm_region_init() to ALIGN_UP(), require that the struct is explicitly a multiple of the header size.
