kernel_map_pages() is static inline function since commit 031bc5743f15 ("mm/debug-pagealloc: make debug-pagealloc boottime configurable"). But there is old declaration in 'arch/powerpc/include/asm/cacheflush.h'. Removing it or changing s/kernel_map_pages/__kernel_map_pages/ in this header file or something can fix this problem? The architecture which has ARCH_SUPPORTS_DEBUG_PAGEALLOC including PPC should not build mm/debug-pagealloc.o _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
