Yes, it's probably the right thing to do.  All the internal routines with "atomic32"
or "atomic64" I assume you mean?

So what's your build process for the cross tools, by the way?  I'm assuming
you're not doing a total bootstrap cross-tool build since you'd need minimal
kernel headers (linux/errno.h or whatever) in that case.  I assume you're using
the host headers to build the cross tool?

So I'm a little confused how the other kernel headers are working out for you,
e.g. <arch/icache.h> is referenced when building the tilegx libgcc.
