This series removes the Sun Cassini, LDOM vswitch and sunvnet drivers.

In a recent patch series that touched these drivers [1], it was suggested
that these drivers should be removed completely. git logs suggest that
there hasn't been any significant feature addition, improvement or fixes
to user-visible bugs in a while. A web search didn't indicate any recent
discussions or any evidence that there are users out there who care about
these drivers.

The idea behind putting out this series is to either establish that these
drivers are used and should be maintained, or remove them.

Anirudh,

The Sun LDOM vswitch and sunvnet drivers are still in use, please do not remove them or the event tracing.
We use them internally and you don't see any discussions because they generally work fine (AFAIK).

Hello Karl,

Thanks for chiming in.

Are there recent platforms where these drivers are used? If yes, do you know which ones? Or are these drivers useful in old/legacy platforms that are still around but perhaps no longer in production?

I think you are also going to break things by removing Sun Cassini support, but I am not using it personally.

You suspect there are users for this driver as well?

What user visible bugs are you referring to here?

I was saying I don't see any evidence of recent bug fixes, which would make sense if these drivers "just work".
