    net: packetengines: switch from 'pci_' to 'dma_' API · 73e283df
    Christophe JAILLET authored
    The wrappers in include/linux/pci-dma-compat.h should go away.
    
    The patch has been generated with the coccinelle script below and has been
    hand modified to replace GFP_ with a correct flag.
    It has been compile tested.
    
    When memory is allocated in 'hamachi_init_one()' (hamachi.c), GFP_KERNEL
    can be used because it is a probe function and no lock is acquired.
    
    When memory is allocated in 'yellowfin_init_one()' (yellowfin.c),
    GFP_KERNEL can be used because it is a probe function and no lock is
    acquired.
