I haven't been able to boot any Tegra2 boards with this patch applied. I'm
guessing that some exceptions for Tegra2 code are still missing, though they
shouldn't work with armv5 either since the AVP is armv4 only. For now I've
conditionalized the -march=armv7-a on !CONFIG_TEGRA2.
Maybe somebody else can shed some light on this. Or perhaps this will be
resolved with Allen's patches anyway?
