    __GFP_COLD looks OK.

    __GFP_COMP I'm not so sure about.
    drivers/char/drm/drm_pci.c:drm_pci_alloc() (and other places like infiniband)
    pass it into dma_alloc_coherent() which some architectures implement via slab. umm,
    arch/arm/mm/consistent.c is one such.

    __GFP_MOVABLE looks OK.
