Revision fbd71844852c9458bf73c7cbdae7189c2d4b377c authored by Ben Hutchings on 27 February 2011, 05:41:35 UTC, committed by Linus Torvalds on 01 March 2011, 01:46:49 UTC 
mm: <asm-generic/pgtable.h> must include <linux/mm_types.h>
 
Commit e2cda3226481 ("thp: add pmd mangling generic functions") replaced
some macros in <asm-generic/pgtable.h> with inline functions.

If the functions are to be defined (not all architectures need them)
then struct vm_area_struct must be defined first.  So include
<linux/mm_types.h>.

Fixes a build failure seen in Debian:
