The commitc296d4dc13("asm-generic: fix a compilation warning") changed asm-generic/cachflush.h to use static inlines instead of macros and as a result the nds32 build with CONFIG_CPU_CACHE_ALIASING=n fails: CC init/main.o In file included from arch/nds32/include/asm/cacheflush.h:43, from include/linux/highmem.h:12, from include/linux/pagemap.h:11, from include/linux/blkdev.h:16, from include/linux/blk-cgroup.h:23, from include/linux/writeback.h:14, from init/main.c:44: include/asm-generic/cacheflush.h:50:20: error: static declaration of 'flush_icache_range' follows non-static declaration static inline void flush_icache_range(unsigned long start, unsigned long end) ^~~~~~~~~~~~~~~~~~ In file included from include/linux/highmem.h:12, from include/linux/pagemap.h:11, from include/linux/blkdev.h:16, from include/linux/blk-cgroup.h:23, from include/linux/writeback.h:14, from init/main.c:44: arch/nds32/include/asm/cacheflush.h:11:6: note: previous declaration of 'flush_icache_range' was here void flush_icache_range(unsigned long start, unsigned long end); ^~~~~~~~~~~~~~~~~~ Surround the inline functions in asm-generic/cacheflush.h by ifdef's so that architectures could override them and add the required overrides to nds32.
