This fixes a compilation error in clang in that a linker section
attribute can't be added to a type:

  arch/x86/mm/mmap.c:34:8: error: '__section__' attribute only applies to functions and global variables struct __read_mostly
  ...

By moving the section attribute to the variable declaration, the
desired effect is achieved.
