I took a look at the patches that was applied to linux-yocto-3.8 to fix
this issue. Seems like it's two patches to memset.S, and both applied
cleanly to linux-boundary as well and leads to a booting kernel. These
patches are also available upstream [1]. Before this memset.S hasn't been
touched since November -08, so I suspect they're totally safe to include in
linux-boundary as well.
