As we never need to directly access the pages we allocate for scratch and the pagetables, and always remap them into the GTT through the dma remapper, we do not need to limit the allocations to lowmem i.e. we can pass in the __GFP_HIGHMEM flag to the page allocation. For backwards compatibility, e.g. certain old GPUs not liking highmem for certain functions that may be accidentally mapped to the scratch page by userspace, keep the GMCH probe as only allocating from DMA32.
