cpu: Move cpu_index field to CPUState
Note that target-alpha accesses this field from TCG, now using a negative offset. Therefore the field is placed last in CPUState. Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change. Move common parts of mips cpu_state_reset() to mips_cpu_reset(). Acked-by: Richard Henderson <rth@twiddle.net> (for alpha) [AF: Rebased onto ppc CPU subclasses and openpic changes] Signed-off-by: Andreas Färber <afaerber@suse.de>
