Hi Abner,

I see, the C Coding Standards Spec tells us th= at "macro guard" should be like "ifndef PROCESSOR_BIND_H_", but there is ve= ry little attention in the current edk2 repo. Anyway, I will fix it in the = next version.

No, you don=E2=80=99t have to remove the tailing =E2=80=9C_= =E2=80=9D. You can check section 5.3.5. in EDK2 C Coding Standards Spec.

Hi Ab= ner,
 

Do I have to remove a "_" at the head and tail? All I found in = MdePkg is that *.h files have two "_" at the head and tail. If you are sure= that EDK II coding style must contain only one "_" at the head and tail, I= will modify it.

Please remove the leading "_" and only keep one trail= ing "_" to follow the edk2 coding standard. RISC-V ProcessorBind.h has the = mistake.
