Linux2.6.38 kernel compilation Error

When compiling the 2.6.38 kernel, the following error occurs:

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] Error 1
Make [1]: *** [ARCH/x86/kernel] Error 2

Make: *** [ARCH/x86] Error 2

Solution:

This is related to a kernel bug. Someone has submitted the patch.
You can also change the two parts in arch/x86/kernel/entry_32.s to compile again. For details, refer to the link:
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.
