X-Git-Tag: v3.12-rc1~23948^2~66
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e7a40d268ec2afab7e0596667cabd2ae53fec8d8;p=kernel%2Fkernel-generic.git

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.
