While copy_to/from_user_page() users are uncommon, there is one in drivers/staging/lustre/lustre/libcfs/linux/linux-curproc.c which leads to the following: ERROR: "sparc32_cachetlb_ops" [drivers/staging/lustre/lustre/libcfs/libcfs.ko] undefined! during routine allmodconfig build coverage. The reason this happens is as follows: In arch/sparc/include/asm/cacheflush_32.h we have: #define flush_cache_page(vma,addr,pfn) \ sparc32_cachetlb_ops->cache_page(vma, addr) #define copy_to_user_page(vma, page, vaddr, dst, src, len) \ do { \ flush_cache_page(vma, vaddr, page_to_pfn(page));\ memcpy(dst, src, len); \ } while (0) #define copy_from_user_page(vma, page, vaddr, dst, src, len) \ do { \ flush_cache_page(vma, vaddr, page_to_pfn(page));\ memcpy(dst, src, len); \ } while (0) However, sparc32_cachetlb_ops isn't exported and hence the error.
