It's CONFIG_ARM_AEABI, which is normally set everywhere. Without this
option, you the kernel is built for the old 'OABI' that forces all non-packed
struct members to be at least 16-bit aligned.
I think Russell still uses OABI kernels on his oldest machines, but it is
incompatible with all modern user space and should probably not be
in the defconfig.
Your patch looks like the correct solution to me.
