    [PATCH] mxcsr patch for i386 & x86-64 · 681b6bf7
    Nitin A. Kamble authored
    This enables proper mxcsr register masking: the magic mask "0xffbf"
    is not necessarily correct for all CPU's, and there is an architected
    way to discover the proper MXCSR feature bits by examining the fxsave
    results.
    
    Please refer to IA32 Software Developer's Manual, Volume 1, Section
    11.6.6 for more details.
