Gary,
Although spin_is_locked() was not defined on some earlier ports to PPC
it has been in all 2.4+ kernels for a long time now. It think that the
#ifdef could be removed.
This is just one of the problems with wrappering kernel functions with
lis_ functions of the same name. (The other is, of course, licensing,
which does _not_ magically change from GPL to LGPL.)
So why are you using these lis_ lock functions at all?
