Actually, it would be better not to have sys_ipc or include/asm-xtensa/ipc.h
at all but rather have all ipc syscalls as separate entry points.

IIRC, parisc is the only architecture to get this right so far, so please
have a look there.

Absolutely true and I think the patch xtensa-remove-old-syscalls.patch
that is in -mm also gets rid of sys_ipc.  If that is the case, then 
include/asm-xtensa/ipc.h can, indeed, be completely removed.

alpha, x86_64 also has this done.
