We have repeat patterns of: if (!use_eager_fpu()) clts(); ... to activate FPU registers, and: if (!use_eager_fpu()) stts(); ... to deactivate them. Encapsulate these in: __fpregs_activate_hw(); __fpregs_activate_hw(); and use them accordingly. Doing this synchronizes the idiom with the fpu->fpregs_active software-flag's handling functions, creating clear patterns of: __fpregs_activate_hw(); __fpregs_activate(fpu); etc., which improves readability.
