There is a funny excercise to run a guest under QEMU without the SLOF firmware and boot into a kernel directly to use petitboot as a boot loader (a more power boot loader than grub and yum), the patchset is posted as "spapr: Kexec style boot". Since there is no SLOF, i.e. no client interface and no RTAS blob, we need to avoid the former and call the latter directly. Also, this implements "client-architecture-support" substiitute for the new environment. This is based on sha1 a2b6f26c264e Christophe Leroy "powerpc/module64: Use symbolic instructions names.". Please comment. Thanks.
