This breaks final link due to missing THREAD_SIZE definition in head.S:

   LD      vmlinux
arch/m68knommu/platform/coldfire/head.o: In function `_clear_bss':
(.head.text+0xa4): undefined reference to `THREAD_SIZE'


Without that asm-offsets.c change it works on my ColdFire boards.
I am happy with it:
