    powerpc: Dynamic DMA zone limits · 1c98025c
    Scott Wood authored
    Platform code can call limit_zone_pfn() to set appropriate limits
    for ZONE_DMA and ZONE_DMA32, and dma_direct_alloc_coherent() will
    select a suitable zone based on a device's mask and the pfn limits that
    platform code has configured.
