Hi,
so there's no need to have two different injectors. Also, the mce_amd_inj interface is much more user-friendly because you can simply write full u64 registers directly.
So merge that functionality into mce-inject. The old /dev/mcelog functionality is still there, behind X86_MCELOG_LEGACY.
Also, the second patch removes register_mce_write_callback() and adds an MCE injector notifier which allows us to have mce-inject be a module and thus be able to modprobe it and remove it on a production system in case we want to do some injecting there.
Later, we might reuse that injector notifier for other stuff if it is deemed interesting.
