    kernel: Don't store FPU status into the reserved area of fxsave
    
    Since each time before the old sv_ex_sw is accessed, fnstsw() is
    always called, it no longer makes any sense to save the temporary
    in the reserved area for fxsave.  And more important: saving the
    FPU status into fxsave area overwrites saved xmm register value.
