Subject: [PATCH] mm: <asm-generic/pgtable.h> must include <linux/mm_types.h>
Date: Sun, 27 Feb 2011 05:41:35 +0000 [thread overview]
Message-ID: <1298785295.3069.61.camel@localhost> (raw)
Commit e2cda322648122dc400c85ada80eaddbc612ef6a '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:
