Chang S. Bae 8bf26758ca x86/fpu: Add XFD state to fpstate ... Add storage for XFD register state to struct fpstate. This will be used to store the XFD MSR state. This will be used for switching the XFD MSR when FPU content is restored. Add a per-CPU variable to cache the current MSR value so the MSR has only to be written when the values are different.
