    x86/fpu: Factor out fpu__flush_thread() from flush_thread() · 81683cc8
    Ingo Molnar authored
    flush_thread() open codes a lot of FPU internals - create a separate
    function for it in fpu/core.c.
    
    Turns out that this does not hurt performance:
    
       text    data     bss     dec     hex filename
       11843039        1884440 1130496 14857975         e2b6f7 vmlinux.before
       11843039        1884440 1130496 14857975         e2b6f7 vmlinux.after
    
    and since this is a slowpath clarity comes first anyway.
    
    We can reconsider inlining decisions after the FPU code has been cleaned up.
