      "message": "mm: introduce pte_special pte bit\n\ns390 for one, cannot implement VM_MIXEDMAP with pfn_valid, due to their memory\nmodel (which is more dynamic than most).  Instead, they had proposed to\nimplement it with an additional path through vm_normal_page(), using a bit in\nthe pte to determine whether or not the page should be refcounted:\n\nvm_normal_page()\n{\n\t...\n        if (unlikely(vma-\u003evm_flags \u0026 (VM_PFNMAP|VM_MIXEDMAP))) {\n                if (vma-\u003evm_flags \u0026 VM_MIXEDMAP) {\n#ifdef s390\n\t\t\tif (!mixedmap_refcount_pte(pte))\n\t\t\t\treturn NULL;\n#else\n                        if (!pfn_valid(pfn))\n                                return NULL;\n#endif\n                        goto out;\n                }\n\t...\n}\n\nThis is fine, however if we are allowed to use a bit in the pte to determine\nrefcountedness, we can use that to _completely_ replace all the vma based\nschemes.  So instead of adding more cases to the already complex vma-based\nscheme, we can have a clearly seperate and simple pte-based scheme (and get\nslightly better code generation in the process):\n\nvm_normal_page()\n{\n#ifdef s390\n\tif (!mixedmap_refcount_pte(pte))\n\t\treturn NULL;\n\treturn pte_page(pte);\n#else\n\t...\n#endif\n}\n\nAnd finally, we may rather make this concept usable by any architecture rather\nthan making it s390 only, so implement a new type of pte state for this.\nUnfortunately the old vma based code must stay, because some architectures may\nnot be able to spare pte bits.  This makes vm_normal_page a little bit more\nugly than we would like, but the 2 cases are clearly seperate.\n\nSo introduce a pte_special pte state, and use it in mm/memory.c.  It is\ncurrently a noop for all architectures, so this doesn\u0027t actually result in any\ncompiled code changes to mm/memory.o.\n\nBTW:\nI haven\u0027t put vm_normal_page() into arch code as-per an earlier suggestion.\nThe reason is that, regardless of where vm_normal_page is actually\nimplemented, the *abstraction* is still exactly the same. Also, while it\ndepends on whether the architecture has pte_special or not, that is the\nonly two possible cases, and it really isn\u0027t an arch specific function --\nthe role of the arch code should be to provide primitive functions and\naccessors with which to build the core code; pte_special does that. We do\nnot want architectures to know or care about vm_normal_page itself, and\nwe definitely don\u0027t want them being able to invent something new there\nout of sight of mm/ code. If we made vm_normal_page an arch function, then\nwe have to make vm_insert_mixed (next patch) an arch function too. So I\ndon\u0027t think moving it to arch code fundamentally improves any abstractions,\nwhile it does practically make the code more difficult to follow, for both\nmm and arch developers, and easier to misuse.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Jared Hulbert \u003cjaredeh@gmail.com\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: Heiko Carstens \u003cheiko.carstens@de.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

      "message": "[PATCH] Standardize pxx_page macros\n\nOne of the changes necessary for shared page tables is to standardize the\npxx_page macros.  pte_page and pmd_page have always returned the struct\npage associated with their entry, while pte_page_kernel and pmd_page_kernel\nhave returned the kernel virtual address.  pud_page and pgd_page, on the\nother hand, return the kernel virtual address.\n\nShared page tables needs pud_page and pgd_page to return the actual page\nstructures.  There are very few actual users of these functions, so it is\nsimple to standardize their usage.\n\nSince this is basic cleanup, I am submitting these changes as a standalone\npatch.  Per Hugh Dickins\u0027 comments about it, I am also changing the\npxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.\n\nSigned-off-by: Dave McCracken \u003cdmccr@us.ibm.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[IA64] rework memory attribute aliasing\n\nThis closes a couple holes in our attribute aliasing avoidance scheme:\n\n  - The current kernel fails mmaps of some /dev/mem MMIO regions because\n    they don\u0027t appear in the EFI memory map.  This keeps X from working\n    on the Intel Tiger box.\n\n  - The current kernel allows UC mmap of the 0-1MB region of\n    /sys/.../legacy_mem even when the chipset doesn\u0027t support UC\n    access.  This causes an MCA when starting X on HP rx7620 and rx8620\n    boxes in the default configuration.\n\nThere\u0027s more detail in the Documentation/ia64/aliasing.txt file this\nadds, but the general idea is that if a region might be covered by\na granule-sized kernel identity mapping, any access via /dev/mem or\nmmap must use the same attribute as the identity mapping.\n\nOtherwise, we fall back to using an attribute that is supported\naccording to the EFI memory map, or to using UC if the EFI memory\nmap doesn\u0027t mention the region.\n\nSigned-off-by: Bjorn Helgaas \u003cbjorn.helgaas@hp.com\u003e\nSigned-off-by: Tony Luck \u003ctony.luck@intel.com\u003e\n"

      "message": "[PATCH] freepgt: hugetlb_free_pgd_range\n\nia64 and ppc64 had hugetlb_free_pgtables functions which were no longer being\ncalled, and it wasn\u0027t obvious what to do about them.\n\nThe ppc64 case turns out to be easy: the associated tables are noted elsewhere\nand freed later, safe to either skip its hugetlb areas or go through the\nmotions of freeing nothing.  Since ia64 does need a special case, restore to\nppc64 the special case of skipping them.\n\nThe ia64 hugetlb case has been broken since pgd_addr_end went in, though it\nprobably appeared to work okay if you just had one such area; in fact it\u0027s\nbeen broken much longer if you consider a long munmap spanning from another\nregion into the hugetlb region.\n\nIn the ia64 hugetlb region, more virtual address bits are available than in\nthe other regions, yet the page tables are structured the same way: the page\nat the bottom is larger.  Here we need to scale down each addr before passing\nit to the standard free_pgd_range.  Was about to write a hugely_scaled_down\nmacro, but found htlbpage_to_page already exists for just this purpose.  Fixed\noff-by-one in ia64 is_hugepage_only_range.\n\nUninline free_pgd_range to make it available to ia64.  Make sure the\nvma-gathering loop in free_pgtables cannot join a hugepage_only_range to any\nother (safe to join huges?  probably but don\u0027t bother).\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
