Eric suggested that unless we have evidence that the new work-around
fixes bugs on SNB, that we should continue to use the HWSTAM work-around
on that chip and use the RC6 voodoo on IVB, thus not potentially causing
regressions on SNB.

For back-porting to older kernels, that's obviously the right plan. I
think it's also the right plan for newer kernels, but I'd love to hear
alternate views on the matter.
