sparc: Use generic idle loop
Add generic cpu_idle support sparc32: - replace call to cpu_idle() with cpu_startup_entry() - add arch_cpu_idle() sparc64: - smp_callin() now include cpu_startup_entry() call so we can skip calling cpu_idle from assembler - add arch_cpu_idle() and arch_cpu_idle_dead() Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: "Srivatsa S.
