cpuidle: stop depending on pm_idle
cpuidle users should call cpuidle_call_idle() directly rather than via (pm_idle)() function pointer. Architecture may choose to continue using (pm_idle)(), but cpuidle need not depend on it: my_arch_cpu_idle() ... if(cpuidle_call_idle()) pm_idle(); cc: Kevin Hilman <khilman@deeprootsystems.com> cc: Paul Mundt <lethal@linux-sh.org> cc: x86@kernel.org Acked-by: H.
