Subject: [PATCH 09/40] UAPI: Make linux/patchkey.h easier to parse [ver #3]

Make linux/patchkey.h easier to parse by:

 (1) Switching the reinclusion guard and the indirect-inclusion checks in
     linux/patchkey.h to put the guard around the outside.

 (2) Making the #elif case associated with the __KERNEL__ guard a nested #if
     in a #else of the __KERNEL__ guard.
