Linux2.6.38内核编译报错

编译2.6.38内核报错：

arch/x86/kernel/entry_32.S: Assembler messages:

arch/x86/kernel/entry_32.S:1422: Error: .size expression for apf_page_fault does not evaluate to a constant
make[2]: *** [arch/x86/kernel/entry_32.o] 错误 1
make[1]: *** [arch/x86/kernel] 错误 2

make: *** [arch/x86] 错误 2

解决办法为：

这个跟内核的一个bug有关。已经有人提交了patch了。
自己也可以改一下 arch/x86/kernel/entry_32.S 中的两处地方再编译，具体请参考链接：
https://lkml.org/lkml/2011/3/20/49

This fixes the problem. The file does not have a maintainer listed, so 
I don't know where else to send it than to the LKML. Please correct 
me or redirect as needed.
