BTW, the above patch breaks IA64 build.

It's fixable but I think that it would be better to just drop this
huge patch and add some cast in powerpc code. the types of SWIOTBL
function arguments don't need to mach to DAM_API.txt though it might
be nice if so. There are other type mismatches. If we really want to
do this cleanups, we should fix up all the mismatches.
