This patchset kills some VM_* flags in vma->vm_flags, as result there appears five free bits. Changes since v2 [ https://lkml.org/lkml/2012/4/7/67 ] * killing VM_EXECUTABLE combined back into single patch * new (the biggest one) patch which kills VM_RESERVED --- Konstantin Khlebnikov (8): mm, x86, pat: rework linear pfn-mmap tracking mm: introduce arch-specific vma flag VM_ARCH_1 mm: kill vma flag VM_INSERTPAGE mm: kill vma flag VM_CAN_NONLINEAR mm: use mm->exe_file instead of first VM_EXECUTABLE vma->vm_file mm: kill vma flag VM_EXECUTABLE and mm->num_exe_file_vmas mm: prepare VM_DONTDUMP for using in drivers mm: kill vma flag VM_RESERVED and mm->reserved_vm counter Suresh Siddha (2): x86, pat: remove the dependency on 'vm_pgoff' in track/untrack pfn vma routines x86, pat: separate the pfn attribute tracking for remap_pfn_range and vm_insert_pfn Documentation/vm/unevictable-lru.txt | 4 - arch/alpha/kernel/pci-sysfs.c | 2 arch/ia64/kernel/perfmon.c | 2 arch/ia64/mm/init.c | 3 - arch/powerpc/kvm/book3s_hv.c | 2 arch/powerpc/oprofile/cell/spu_task_sync.c | 15 +--- arch/sparc/kernel/pci.c | 2 arch/tile/mm/elf.c | 19 ++--- arch/unicore32/kernel/process.c | 2 arch/x86/mm/pat.c | 89 ++++++++++++++++------ arch/x86/xen/mmu.c | 3 - drivers/char/mbcs.c | 2 drivers/char/mem.c | 2 drivers/char/mspec.c | 2 drivers/gpu/drm/drm_gem.c | 2 drivers/gpu/drm/drm_vm.c | 10 -- drivers/gpu/drm/exynos/exynos_drm_gem.c | 2 drivers/gpu/drm/gma500/framebuffer.c | 3 - drivers/gpu/drm/ttm/ttm_bo_vm.c | 4 - drivers/gpu/drm/udl/udl_fb.c | 2 drivers/infiniband/hw/ehca/ehca_uverbs.c | 4 - drivers/infiniband/hw/ipath/ipath_file_ops.c | 2 drivers/infiniband/hw/qib/qib_file_ops.c | 2 drivers/media/video/meye.c | 2 drivers/media/video/omap/omap_vout.c | 2 drivers/media/video/sn9c102/sn9c102_core.c | 3 - drivers/media/video/usbvision/usbvision-video.c | 3 - drivers/media/video/videobuf-dma-sg.c | 2 drivers/media/video/videobuf-vmalloc.c | 2 drivers/media/video/videobuf2-memops.c | 2 drivers/media/video/vino.c | 2 drivers/misc/carma/carma-fpga.c | 2 drivers/misc/sgi-gru/grufile.c | 5 - drivers/mtd/mtdchar.c | 2 drivers/oprofile/buffer_sync.c | 17 +--- drivers/scsi/sg.c | 2 drivers/staging/android/ashmem.c | 1 drivers/staging/media/easycap/easycap_main.c | 2 drivers/staging/omapdrm/omap_gem_dmabuf.c | 2 drivers/staging/tidspbridge/rmgr/drv_interface.c | 2 drivers/uio/uio.c | 4 - drivers/usb/mon/mon_bin.c | 2 drivers/video/68328fb.c | 2 drivers/video/aty/atyfb_base.c | 3 - drivers/video/fb-puv3.c | 3 - drivers/video/fb_defio.c | 2 drivers/video/fbmem.c | 3 - drivers/video/gbefb.c | 2 drivers/video/omap2/omapfb/omapfb-main.c | 2 drivers/video/sbuslib.c | 5 - drivers/video/smscufx.c | 1 drivers/video/udlfb.c | 1 drivers/video/vermilion/vermilion.c | 1 drivers/video/vfb.c | 1 drivers/xen/gntalloc.c | 2 drivers/xen/gntdev.c | 2 drivers/xen/privcmd.c | 3 - fs/9p/vfs_file.c | 1 fs/binfmt_elf.c | 4 - fs/binfmt_elf_fdpic.c | 2 fs/btrfs/file.c | 2 fs/ceph/addr.c | 2 fs/cifs/file.c | 1 fs/ext4/file.c | 2 fs/fuse/file.c | 1 fs/gfs2/file.c | 2 fs/hugetlbfs/inode.c | 2 fs/nfs/file.c | 1 fs/nilfs2/file.c | 2 fs/ocfs2/mmap.c | 2 fs/proc/task_mmu.c | 2 fs/ubifs/file.c | 1 fs/xfs/xfs_file.c | 2 include/asm-generic/pgtable.h | 57 ++++++++------ include/linux/fs.h | 2 include/linux/mempolicy.h | 2 include/linux/mm.h | 69 +++++++---------- include/linux/mm_types.h | 2 include/linux/mman.h | 1 kernel/auditsc.c | 13 --- kernel/events/core.c | 2 kernel/fork.c | 24 ------ mm/filemap.c | 2 mm/filemap_xip.c | 3 - mm/fremap.c | 14 ++- mm/huge_memory.c | 22 +---- mm/ksm.c | 8 +- mm/madvise.c | 8 +- mm/memory.c | 62 ++++++++------- mm/mlock.c | 2 mm/mmap.c | 29 +------ mm/nommu.c | 21 ++--- mm/shmem.c | 3 - mm/vmalloc.c | 3 - security/selinux/selinuxfs.c | 2 security/tomoyo/util.c | 9 -- sound/core/pcm_native.c | 6 + sound/usb/usx2y/us122l.c | 2 sound/usb/usx2y/usX2Yhwdep.c | 2 sound/usb/usx2y/usx2yhwdeppcm.c | 2 100 files changed, 303 insertions(+), 370 deletions(-) -- Signature -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
