The addition of the lzo tree to linux-next caused this problem for ARM
imx_v6_v7_defconfig:

In file included from /home/arnd/linux-arm/arch/arm/boot/compressed/decompress.c:40:0:
/home/arnd/linux-arm/arch/arm/boot/compressed/../../../../lib/decompress_unlzo.c:34:34: fatal error: lzo/lzo1x_decompress.c: No such file or directory

Since the file was renamed, anything including it needs to be updated to the
new file name.
