.inject_flags and .finished are two variables. I think you try to avoid
using .inject_flags. But I think it is OK to use .inject_flags.

I don't do that because I don't think your patch is in another way and
much better.

When I say: "I don't think it is necessary". I do think so really.

I think my patch with title:

[BUGFIX -v2] x86, mce, inject: Make injected mce valid only during faked handler call

fixes this issue correctly.

Hi, Ingo and Peter,

what are your idea about the patch above? Maybe you don't like the
naming style of MCJ_XXX. But I think if they need to be changed, it
should be in another patch. And H.Seto has posted the patch for it.

Best Regards,
Huang Ying
