Christophe Leroy 0df977eafc powerpc/6xx: Don't use SPRN_SPRG2 for storing stack pointer while in RTAS ... When calling RTAS, the stack pointer is stored in SPRN_SPRG2 in order to be able to restore it in case of machine check in RTAS. As machine check is not a perfomance critical path, this patch frees SPRN_SPRG2 by using a field in thread struct instead.
