      "message": "mm: re-architect the VM_UNPAGED logic\n\nThis replaces the (in my opinion horrible) VM_UNMAPPED logic with very\nexplicit support for a \"remapped page range\" aka VM_PFNMAP.  It allows a\nVM area to contain an arbitrary range of page table entries that the VM\nnever touches, and never considers to be normal pages.\n\nAny user of \"remap_pfn_range()\" automatically gets this new\nfunctionality, and doesn\u0027t even have to mark the pages reserved or\nindeed mark them any other way.  It just works.  As a side effect, doing\nmmap() on /dev/mem works for arbitrary ranges.\n\nSparc update from David in the next commit.\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] unpaged: VM_UNPAGED\n\nAlthough we tend to associate VM_RESERVED with remap_pfn_range, quite a few\ndrivers set VM_RESERVED on areas which are then populated by nopage.  The\nPageReserved removal in 2.6.15-rc1 changed VM_RESERVED not to free pages in\nzap_pte_range, without changing those drivers not to set it: so their pages\njust leak away.\n\nLet\u0027s not change miscellaneous drivers now: introduce VM_UNPAGED at the core,\nto flag the special areas where the ptes may have no struct page, or if they\nhave then it\u0027s not to be touched.  Replace most instances of VM_RESERVED in\ncore mm by VM_UNPAGED.  Force it on in remap_pfn_range, and the sparc and\nsparc64 io_remap_pfn_range.\n\nRevert addition of VM_RESERVED to powerpc vdso, it\u0027s not needed there.  Is it\nneeded anywhere?  It still governs the mm-\u003ereserved_vm statistic, and special\nvmas not to be merged, and areas not to be core dumped; but could probably be\neliminated later (the drivers are probably specifying it because in 2.4 it\nkept swapout off the vma, but in 2.6 we work from the LRU, which these pages\ndon\u0027t get on).\n\nUse the VM_SHM slot for VM_UNPAGED, and define VM_SHM to 0: it serves no\npurpose whatsoever, and should be removed from drivers when we clean up.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nAcked-by: William Irwin \u003cwli@holomorphy.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
