Hi,
I got below build error by "make at91x40_defconfig; make".

  LD      init/built-in.o
fs/built-in.o: In function `copy_strings':
super.c:(.text+0x634c): undefined reference to `flush_kernel_dcache_page'
super.c:(.text+0x63d4): undefined reference to `flush_kernel_dcache_page'
lib/built-in.o: In function `sg_miter_stop':
strnlen_user.c:(.text+0x3394): undefined reference to `flush_kernel_dcache_page'
make: *** [vmlinux] Error 1

Any idea to fix this?

Thanks,
Axel
