Subject: [PATCH v2 0/5] eagerfpu patches for tip/x86/fpu

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).

Suresh Siddha (5):
  x86, fpu: decouple non-lazy/eager fpu restore from xsave
  x86, fpu: enable eagerfpu by default for xsaveopt
  x86, fpu: move check_fpu() after alternative_instructions()
  x86, fpu: make eagerfpu= boot param tri-state
  x86, fpu: remove cpu_has_xmm check in the fx_finit()
