    Pull x86 FPU updates from Ingo Molnar:
     "The main changes in this cycle were:
    
       - do a large round of simplifications after all CPUs do 'eager' FPU
         context switching in v4.9: remove CR0 twiddling, remove leftover
         eager/lazy bts, etc (Andy Lutomirski)
    
       - more FPU code simplifications: remove struct fpu::counter, clarify
         nomenclature, remove unnecessary arguments/functions and better
         structure the code (Rik van Riel)"
