Building allmodconfig images for sparc32 generates warnings such as arch/sparc/include/asm/cacheflush_32.h:40:37: warning: 'struct page' declared inside parameter list This results in odd warnings such as arch/sparc/include/asm/cacheflush_32.h:40:6: note: expected 'struct page *' but argument is of type 'struct page *' With recent compilers (gcc 5.5.0 and later), this warning turns into a build error when compiling drivers/staging/media/omap4iss/iss_video.c. ./include/linux/highmem.h: In function 'copy_user_highpage': ./include/linux/highmem.h:233:36: error: passing argument 1 of 'sparc_flush_page_to_ram' from incompatible pointer type Declare struct page to fix the problem.
