Excerpts from Christophe Leroy's message of December 9, 2021 3:18 am: > Unlike most architectures, powerpc can only define at runtime > if it is going to use the generic arch_get_unmapped_area() or not. > > Today, powerpc has a copy of the generic arch_get_unmapped_area() > because when selection HAVE_ARCH_UNMAPPED_AREA the generic > arch_get_unmapped_area() is not available. > > Rename it generic_get_unmapped_area() and make it independent of > HAVE_ARCH_UNMAPPED_AREA. > > Do the same for arch_get_unmapped_area_topdown() versus > HAVE_ARCH_UNMAPPED_AREA_TOPDOWN. > > Do the same for hugetlb_get_unmapped_area() versus > HAVE_ARCH_HUGETLB_UNMAPPED_AREA. > Reviewed-by: Nicholas Piggin <npiggin@xxxxxxxxx> > Signed-off-by: Christophe Leroy <christophe.leroy@xxxxxxxxxx> > --- > fs/hugetlbfs/inode.c | 17 +++++++++++++---- > include/linux/hugetlb.h | 5 +++++ > include/linux/sched/mm.h | 9 +++++++++ > mm/mmap.c | 31 ++++++++++++++++++++++++------- > 4 files changed, 51 insertions(+), 11 deletions(-) >
