Xiang Xiao d80c2d7419 arch/arm: Remove all lazy fpu related code 
since it is broken and inefficient, and then removed by:
commit dc961baaea

    arm/armv7-[a|r]: move fpu save/restore to assembly handler

    Save/Restore FPU registers in C environment is dangerous practive,
    which cannot guarantee the compiler won't generate the assembly code
    with float point registers, especially in interrupt handling
