Soby Mathew 42cae5a166 PSCI: Set ON_PENDING state early during CPU_ON ... In the debug build of the function get_power_on_target_afflvl(), there is a check to ensure that the CPU is emerging from a SUSPEND or ON_PENDING state. The state is checked without acquiring the lock for the CPU node. The state could be updated to ON_PENDING in psci_afflvl_on() after the target CPU has been powered up. This results in a race condition which could cause the check for the ON_PENDING state in get_power_on_target_afflvl() to fail. This patch resolves this race condition by setting the state of the target CPU to ON_PENDING before the platform port attempts to power it on. The target CPU is thus guaranteed to read the correct the state. In case the power on operation fails, the state of the CPU is restored to OFF.
