x86: use _ASM_EXTABLE macro in arch/x86/lib/mmx_32.c
Use the _ASM_EXTABLE macro from <asm/asm.h>, instead of open-coding __ex_table entires in arch/x86/lib/mmx_32.c. Signed-off-by: H. Peter Anvin <hpa@zytor.com> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
