Hi, This series adds guards around vma's but setting a pages at the beginning and at the end that work as padding. The first user of the vma guard are scanout objects which don't need anymore to add scratch to all the unused ggtt's and speeding up up considerably the boot and resume by several hundreds of milliseconds up to over a full second in slower machines.
