I found it when went through system init code, it was introduced in this
commit and looks very obvious: 

commit 19d0cfe9ddfdf7afa8d1765ab0bd2a7dd30e47c9
Author: Bob Moore <robert.moore@...el.com>
Date:   Tue Jun 10 15:54:40 2008 +0800

    ACPICA: Update DMAR and SRAT table definitions

If there has been a mechanism to check them, I am fine to leave it as is
or the tools like lindent to deal with it.

Thanks
Baoquan
