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. Signed-off-by: David S.
