    x86/fpu: Rename sanitize_i387_state() to fpstate_sanitize_xstate() · d0903193
    Ingo Molnar authored
    So the sanitize_i387_state() function has the following purpose:
    on CPUs that support optimized xstate saving instructions, an
    FPU fpstate might end up having partially uninitialized data.
    
    This function initializes that data.
    
    Note that the function name is a misnomer and confusing on two levels,
    not only is it not i387 specific at all, but it is the exact opposite:
    it only matters on xstate CPUs.
    
    So rename sanitize_i387_state() and __sanitize_i387_state() to
    fpstate_sanitize_xstate() and __fpstate_sanitize_xstate(),
    to clearly express the purpose and usage of the function.
    
    We'll further clean up this function in the next patch.
