Subject__buggy_fxsr_alignment() not found.
My system is:
AMD K6-II 450

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);
But there is no realisation of this function in source files.
When I comment the lines above, everything works.
