    x86/fpu: Add CONFIG_X86_DEBUG_FPU=y FPU debugging code · e97131a8
    Ingo Molnar authored
    There are various internal FPU state debugging checks that never
    trigger in practice, but which are useful for FPU code development.
    
    Separate these out into CONFIG_X86_DEBUG_FPU=y, and also add a
    couple of new ones.
    
    The size difference is about 0.5K of code on defconfig:
    
       text        data     bss          filename
       15028906    2578816  1638400      vmlinux
       15029430    2578816  1638400      vmlinux
    
    ( Keep this enabled by default until the new FPU code is debugged. )
