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.
