    x86/fpu: Simplify fpstate_init_curr() usage · c4d72e2d
    Ingo Molnar authored
    Now that fpstate_init_curr() is not doing implicit allocations
    anymore, almost all uses of it involve a very simple pattern:
    
    	if (!fpu->fpstate_active)
    		fpstate_init_curr(fpu);
    
    which is basically activating the FPU fpstate if it was not active
    before.
    
    So propagate the check into the function itself, and rename the
    function according to its new purpose:
    
    	fpu__activate_curr(fpu);
