This series bases on 5.8-rc4 and refactors the SDEI client driver. It's the preparatory work of virtualizing SDEI afterwords. The series is organized as below: * PATCH[1-11] refactors and clean up the code. They shouldn't cause any functional changes. * PATCH[12] exposes "struct sdei_event", which will be dereferenced on virtualizing SDEI. After it's applied, the SDEI event is identified by the instance of "struct sdei_event" instead of event number. * PATCH[13] retrieves the signaled property of the SDEI event when it's populated. It's needed by SDEI virtualization afterwards. * PATCH[14] exposes API (sdei_event_get_info()), which is needed by SDEI virtualization either. Testing ======= I have the SDEI virtualization code implemented as part of KVM module. With that, the SDEI event can be registered/unregistered/enabled/disabled. Also, the SDEI event can be injected from host and the guest handler runs properly.
