 You can't just remove a UAPI header like this, something will break; cf. 
arch/arc/include/uapi/asm/setup.h, or arch/x86/include/uapi/asm/setup.h if 
you want it brief.

 I suggest that you fold it into 01/26 (it makes no sense to have empty 
multiple inclusion protection), and likewise for the relevant remaining 
headers.
