    [SPARC64]: Respect gfp_t argument to dma_alloc_coherent(). · 42f14237

    Using asm-generic/dma-mapping.h does not work because pushing
    the call down to pci_alloc_coherent() causes the gfp_t argument
    of dma_alloc_coherent() to be ignored.
    
    Fix this by implementing things directly, and adding a gfp_t
    argument we can use in the internal call down to the PCI DMA
    implementation of pci_alloc_coherent().
    
    This fixes massive memory corruption when using the sound driver
    layer, which passes things like __GFP_COMP down into these
    routines and (correctly) expects that to work.
