由于ptrace.h文件导致的内核编译出错的解决方法

编译内核到了make bzImage时出现如下错误：

make[1]: *** [arch/x86/kernel] Error 2

注意红色标注的两行，说明ptrace.c 文件中第1472行的函数syscall_trace_leave和ptrace.h文件中该函数的声明有冲突，只要将ptrace.h文件中的函数声明改得和ptrace.c中的相同即可。另外，有人专门针对这个错误写了个补丁，地址为https://patchwork.kernel.org/patch/1301031/  。

PS ：以前像遇到这种问题的时候，总会认为是自己哪儿出了问题。这个问题让我懂得linux也是像我一样的程序员写出来的，他们也会犯一些常人会犯的错误，所以Linux需要全世界的程序员一起改进  。
