[XEN PATCH 08/13] x86/mm: address violations of MISRA C:2012 Directive 4.10



Add inclusion guards to address violations of
MISRA C:2012 Directive 4.10 ("Precautions shall be taken in order
to prevent the contents of a header file being included more than
once").

C files, if included somewhere, need to comply with the guideline.

Mechanical change.
