omap2plus_defconfig fails to compile on linux-next with OMAP2 support

Tony,

linux-next as of 20101001 fails to build on omap2plus_defconfig with multiple
build errors. I've resolved many of those, but this one remains as long as CONFIG_ARCH_OMAP2 is enabled.

I'm not sure how to fix this, so just reporting it for now.
