This causes the following compile error with gcc 3.4 on i386:

<--  snip  -->

...
  CC      mm/hugetlb.o
mm/hugetlb.c: In function `enqueue_huge_page':
include/linux/mm.h:500: sorry, unimplemented: inlining failed in call to 
'page_zone': function not considered for inlining
mm/hugetlb.c:486: sorry, unimplemented: called from here
make[1]: *** [mm/hugetlb.o] Error 1
make: *** [mm] Error 2

<--  snip  -->


This patch fixes this compile error.
