The gfp assignment has been commented out in ancient times, combined with the code comment, obviously it's not needed since then. Let's remove the whole ifdeffery block so that GFP_DMA searching won't point to this. Signed-off-by: Baoquan He <redacted> --- arch/parisc/kernel/pci-dma.c | 8 -------- 1 file changed, 8 deletions(-)
