This doesn't seem to be something that was added with this patch. This 
COMPILE_BUG_ON() has been here for quite some time... I'm not sure why 
it triggers now.

The mips:allmodconfig works here as long as I switch to 
CPU_LITTLE_ENDIAN (no big-endian compiler). But I'm at a different 
HEAD, and I can't find commit d67bc7812221606e1886620a357b13f906814af7 
anywhere, in which repo is that found?

Cheers,
-Paul
