[PATCH] kprobe: kprobe-booster fix for NX support on i386

[Masami Hiramatsu <hiramatu@sdl.hitachi.co.jp>]

Hi, Andrew

Here is the patch to fix kprobe-booster against linux-2.6.16-rc5-mm1.
 - Fix to assign the correct address of the instruction buffer.
   From linux-2.6.16-rc5, the ainsn.insn on i386 arch became a pointer
   instead of an array itself.

Best regards,
