Main reason for white-list at this point is not to be side-tracked by real or potential erratas on older CPUs. Focussing on getting the support for this feature on current and future CPUs. If older CPUs have survived all these days without this feature, they should be doing OK.OK, note previous question: what is the motivation for having this as a whitelist (as opposed to a blacklist)?Venkatesh could tell?
well, the upside would be that since most testing of Linux kernels is done on _old_ hardware (people tend to risk their old hw first ;-), we'd get faster convergence of the codebase, even though we have the risk of erratas (known and unknown ones alike). Code that artificially limits its utility is almost always slow to stabilize.
