The Intel interrupt handling code is in arch/i386/kernel/irq.
intel系统的中断处理代码位于arch/i386/kernel/irq.
The include/asm subdirectory is a soft link to the real include directory needed for this architecture, for example include/asm-i386.
mm This directory contains all of the memory management code. The architecture specific memory management code lives down in archmm目录下， 如arch/i386/mm/fault.c 。
这个socketcall 系统调用在i386架构上是多元的，因此需要使用-Fa0=2 选项将所生成的审计记录仅仅限制在bind上。
