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.
