This was solved by a patch that went into Dave's DRM pull request for
3.10 by adding:
depends on ARCH_TEGRA || ARCH_MULTIPLATFORM
to the Kconfig entry for TEGRA_HOST1X. The plan was to eventually remove
ARCH_TEGRA from that condition after 3.10 since ARCH_MULTIPLATFORM will
include ARCH_TEGRA anyway. I'm not sure why that patch hasn't made it
into linux-next yet, though.
