[PATCH] Sparsemem build fix
From: Ralf Baechle <ralf@linux-mips.org> <linux/mmzone.h> uses PAGE_SIZE, PAGE_SHIFT from <asm/page.h> without including that header itself. For some sparsemem configurations this may result in build errors like: CC init/initramfs.o In file included from include/linux/gfp.h:4, from include/linux/slab.h:15, from include/linux/percpu.h:4, from include/linux/rcupdate.h:41, from include/linux/dcache.h:10, from include/linux/fs.h:226, from init/initramfs.c:2: include/linux/mmzone.h:498:22: warning: "PAGE_SHIFT" is not defined In file included from include/linux/gfp.h:4, from include/linux/slab.h:15, from include/linux/percpu.h:4, from include/linux/rcupdate.h:41, from include/linux/dcache.h:10, from include/linux/fs.h:226, from init/initramfs.c:2: include/linux/mmzone.h:526: error: `PAGE_SIZE' undeclared here (not in a function) include/linux/mmzone.h: In function `__pfn_to_section': include/linux/mmzone.h:573: error: `PAGE_SHIFT' undeclared (first use in this function) include/linux/mmzone.h:573: error: (Each undeclared identifier is reported only once include/linux/mmzone.h:573: error: for each function it appears in.) include/linux/mmzone.h: In function `pfn_valid': include/linux/mmzone.h:578: error: `PAGE_SHIFT' undeclared (first use in this function) make[1]: *** [init/initramfs.o] Error 1 make: *** [init] Error 2 Signed-off-by: Ralf Baechle <ralf@linux-mips.org> Seems-reasonable-to: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
