    Hello!
    My system is:
    AMD K6-II 450
    Linux-2.4.24
    glibc-2.2.5

    I cannot compile 2.4.24 kernel because linker says:
    init/main.o: In function `check_fpu':
    init/main.o(.text.init+0x53): undefined reference to `__buggy_fxsr_alignment'

    It's prototype is in inculude/asm-i386/bugs.h:
    -----
    /* Enable FXSR and company _before_ testing for FP problems. */
            /*
             * Verify that the FXSAVE/FXRSTOR data will be 16-byte aligned.
             */
            if (offsetof(struct task_struct, thread.i387.fxsave) & 15) {
                  extern void __buggy_fxsr_alignment(void);
                  __buggy_fxsr_alignment();
    -----
    But there is no realisation of this function in source files.
    When I comment the lines above, everything works.
