Subject: [PATCH v2 00/10] mm: vma->vm_flags diet

This patch-set moves/kills some VM_* flags in vma->vm_flags bit-field,
as result there appears four free bits.

changes from v1:

* "mm, drm/udl: fixup vma flags on mmap" already merged
* two new x86/PAT cleanup/rework patches from Suresh Siddha
* "mm: kill vma flag VM_EXECUTABLE" splitted into three pieces

---

Konstantin Khlebnikov (8):
      mm, x86, pat: rework linear pfn-mmap tracking
      mm: introduce vma flag VM_ARCH_1
      mm: kill vma flag VM_CAN_NONLINEAR
      mm: kill vma flag VM_INSERTPAGE
      mm: use mm->exe_file instead of first VM_EXECUTABLE vma->vm_file
      mm: kill vma flag VM_EXECUTABLE
      mm: kill mm->num_exe_file_vmas and keep mm->exe_file until final mmput()
      mm: move madvise vma flags to the end

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
