I've applied this patch on top.

Subject: [PATCH] ARM: tegra: build assembly files with -march=armv7-a

The tegra assembly files are written for ARMv7 and are not compatible
with ARMv6, which leads to build warnings when compiling a dual
ARMv6/v7 kernel. Since this code is only ever run on Tegra ARMv7
hardware, we can tell the assembler which architecture level to
use.

Ah yes, I hit that problem too, but wasn't sure how to solve it. The
patch below looks good. Now I must go try a combo bcm2835+Tegra kernel
on both devices...
