linux 系统调用中断向量表
对于分析TCP/IP协议栈中用户空间程序的开发会用到许多系统调用，系统调用的时候程序由用户态陷入到内核态，根据系统调用中断向量表来查询，具体内核该做什么事情。对于x86而言，64位系统的linux 系统调用向量表是向下兼容32位系统的。 系统调用表的文件在目录linux-3.9.3/arch/x86/syscalls下：syscall_32.tbl syscall_64.tbl。 其他CPU的系统调用表也是在同层级的目录下。如mips 32位系统的系统调用中断向量表在文件linux-3.9.3/arch/mips/kernel/scall32-o32.S中定义。
x86 64位系统调用中断向量表如下：
#
# 64-bit system call numbers and entry vectors
#
# The format is:
# <number> <abi> <name> <entry point>
#
# The abi is "common", "64" or "x32" for this file.
