v2 version of the previous patchset https://lkml.org/lkml/2012/9/7/548 that decouples eagerfpu into a synthetic cpuid feature.
changes from v1: * Made "eagerfpu=" boot parameter tri-state * removed the cpu_has_xmm check in the fx_finit (not related to eagerfpu per-say, but this patchset touches that area of code).
