[PATCH v5 RESEND 01/17] asm-generic/iomap.h: remove ARCH_HAS_IOREMAP_xx macros
Let's use '#define ioremap_xx' and "#ifdef ioremap_xx" instead. For each architecture to remove defined ARCH_HAS_IOREMAP_xx macros in To remove defined ARCH_HAS_IOREMAP_xx macros in of each ARCH, the ARCH's own ioremap_wc|wt|np definition need be above "#include . Otherwise the redefinition error would be seen during compiling. So 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, 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 in the middle of . Let's rely on .
