Okay! Come on! You SMP guys! Please help me add support for SMP! I see no problem in doing this except that I'm not driving around my block in a Mercedes. Not even in a broken "A Klasse" :)
If you tell me how to do it, I can implement it and send it to you for testing.
Implementing SMP is no problem in both the device file and proc FS concept.
But which one should I choose??
I see no point in working on one when someone comes around the corner a few weeks later and tells me that MSR support is not gonna be included in the kernel because it uses the wrong interface!

Could you do this?

P.S.: Please don't get me wrong. I very much appreciate all your hard work at Linux, esp. the recent p5bugfix :).
