[PATCH v3 00/10] mm: vma->vm_flags diet

From: Konstantin Khlebnikov
Date: Tue Jul 31 2012 - 06:34:04 EST

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
