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
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: CC [M] drivers/media/dvb/mantis/mantis_pci.o In file included from arch/arm/include/asm/pgtable.h:460, from drivers/media/dvb/mantis/mantis_pci.c:25: include/asm-generic/pgtable.h: In function 'ptep_test_and_clear_young': include/asm-generic/pgtable.h:29: error: dereferencing pointer to incomplete type Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
