Clearly the patch is not intended for sparc64. Maybe adding devm_ioremap_uc is rather not safe right now. Although, We could declare dummies for these architectures like it has been for powerpc. I just noticed another driver having this issue, and fixed with direct calls to ioremap_uc(). 3cc2dac5be3f2: drivers/video/fbdev/atyfb: Replace MTRR UC hole with strong UC Tuowen
