Comments in head.S suggest that the iSeries naca has a fixed address, because tools expect to find it there. The only tool which appears to access the naca is addRamDisk, but both the in-kernel version and the version used in RHEL and SuSE in fact locate the NACA the same way as the hypervisor does, by following the pointer in the hvReleaseData structure. Since the requirement for a fixed address seems to be obsolete, this patch removes the naca from head.S and replaces it with a normal C initializer. For good measure, it removes an old version of addRamDisk.c which was sitting, unused, in the ppc32 tree.
