For architectures defined ARCH_HAS_IOREMAP_xx macros in , the relevant adjustments are made to avoid compiling error: loongarch: - doesn't include , defining ARCH_HAS_IOREMAP_WC is redundant, so simply remove it. m68k: - selected GENERIC_IOMAP, so has been added in , and is included above , so simply remove ARCH_HAS_IOREMAP_WT defining. mips: - move "#include " below ioremap_wc definition in powerpc: - remove "#include " in because it's duplicated with the one in , let's rely on the latter. x86: - selected GENERIC_IOMAP, remove #include at the middle of . Let's rely on . This is a preparation patch so that Later patch don't need to add ARCH_HAS_IOREMAP_xx macro.
