      "message": "hugepage: fix broken check for offset alignment in hugepage mappings\n\nFor hugepage mappings, the file offset, like the address and size, needs to\nbe aligned to the size of a hugepage.\n\nIn commit 68589bc353037f233fe510ad9ff432338c95db66, the check for this was\nmoved into prepare_hugepage_range() along with the address and size checks.\n But since BenH\u0027s rework of the get_unmapped_area() paths leading up to\ncommit 4b1d89290b62bb2db476c94c82cf7442aab440c8, prepare_hugepage_range()\nis only called for MAP_FIXED mappings, not for other mappings.  This means\nwe\u0027re no longer ever checking for an aligned offset - I\u0027ve confirmed that\nmmap() will (apparently) succeed with a misaligned offset on both powerpc\nand i386 at least.\n\nThis patch restores the check, removing it from prepare_hugepage_range()\nand putting it back into hugetlbfs_file_mmap().  I\u0027m putting it there,\nrather than in the get_unmapped_area() path so it only needs to go in one\nplace, than separately in the half-dozen or so arch-specific\nimplementations of hugetlb_get_unmapped_area().\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Andi Kleen \u003cak@suse.de\u003e\nCc: \"David S.

Since\nmin_low_pfn is calculated in build_node_map, so in this case, min_low_pfn\nwill be greater than kernel code and data.\n\nBecause pages inside initmem are freed and reused later, we saw\npfn_valid check fail on those pages.\n\nI think this theoretically happen on a normal kernel. When I check\nmin_low_pfn and max_low_pfn calculation in contig.c and discontig.c.\nI found more issues than this.\n\n1. min_low_pfn and max_low_pfn calculation is inconsistent between\ncontig.c and discontig.c,\nmin_low_pfn is calculated as the first page number of boot memmap in\ncontig.c (Why? Though this may work at the most of the time, I don\u0027t\nthink it is the right logic). It is calculated as the lowest physical\nmemory page number bypass reserved regions in discontig.c.\nmax_low_pfn is calculated include reserved regions in contig.c. It is\ncalculated exclude reserved regions in discontig.c.\n\n2. If kernel code and data region is happen to be at the begin or the\nend of physical memory, when min_low_pfn and max_low_pfn calculation is\nbypassed kernel code and data, pages in initmem will report bad.\n\n3. initrd is also in reserved regions, if it is at the begin or at the\nend of physical memory, kernel will refuse to reuse the memory.

      "message": "[PATCH] shared page table for hugetlb page\n\nFollowing up with the work on shared page table done by Dave McCracken.  This\nset of patch target shared page table for hugetlb memory only.\n\nThe shared page table is particular useful in the situation of large number of\nindependent processes sharing large shared memory segments.  In the normal\npage case, the amount of memory saved from process\u0027 page table is quite\nsignificant.  For hugetlb, the saving on page table memory is not the primary\nobjective (as hugetlb itself already cuts down page table overhead\nsignificantly), instead, the purpose of using shared page table on hugetlb is\nto allow faster TLB refill and smaller cache pollution upon TLB miss.\n\nWith PT sharing, pte entries are shared among hundreds of processes, the cache\nconsumption used by all the page table is smaller and in return, application\ngets much higher cache hit ratio.  One other effect is that cache hit ratio\nwith hardware page walker hitting on pte in cache will be higher and this\nhelps to reduce tlb miss latency.  These two effects contribute to higher\napplication performance.\n\nSigned-off-by: Ken Chen \u003ckenneth.w.chen@intel.com\u003e\nAcked-by: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Dave McCracken \u003cdmccr@us.ibm.com\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: \"David S.

That will eventually call down to the\nnon-hugepage version of unmap_page_range().  On ppc64, at least, that will\ncause serious problems if there are any existing hugepage pagetable entries in\nthe vicinity - for example if there are any other hugepage mappings under the\nsame PUD.  unmap_page_range() will trigger a bad_pud() on the hugepage pud\nentries.  I suspect this will also cause bad problems on ia64, though I don\u0027t\nhave a machine to test it on.\n\n(Hugh:)\n\nprepare_hugepage_range() should check file offset alignment when it checks\nvirtual address and length, to stop MAP_FIXED with a bad huge offset from\nunmapping before it fails further down.  PowerPC should apply the same\nprepare_hugepage_range alignment checks as ia64 and all the others do.\n\nThen none of the alignment checks in hugetlbfs_file_mmap are required (nor\nis the check for too small a mapping); but even so, move up setting of\nVM_HUGETLB and add a comment to warn of what David Gibson discovered - if\nhugetlbfs_file_mmap fails before setting it, do_mmap_pgoff\u0027s unmap_region\nwhen unwinding from error will go the non-huge way, which may cause bad\nbehaviour on architectures (powerpc and ia64) which segregate their huge\nmappings into a separate region of the address space.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: \"David S.

      "message": "[PATCH] make PROT_WRITE imply PROT_READ\n\nMake PROT_WRITE imply PROT_READ for a number of architectures which don\u0027t\nsupport write only in hardware.\n\nWhile looking at this, I noticed that some architectures which do not\nsupport write only mappings already take the exact same approach.  For\nexample, in arch/alpha/mm/fault.c:\n\n\"\n        if (cause \u003c 0) {\n                if (!(vma-\u003evm_flags \u0026 VM_EXEC))\n                        goto bad_area;\n        } else if (!cause) {\n                /* Allow reads even for write-only mappings */\n                if (!(vma-\u003evm_flags \u0026 (VM_READ | VM_WRITE)))\n                        goto bad_area;\n        } else {\n                if (!(vma-\u003evm_flags \u0026 VM_WRITE))\n                        goto bad_area;\n        }\n\"\n\nThus, this patch brings other architectures which do not support write only\nmappings in-line and consistent with the rest.  I\u0027ve verified the patch on\nia64, x86_64 and x86.\n\nAdditional discussion:\n\nSeveral architectures, including x86, can not support write-only mappings.\nThe pte for x86 reserves a single bit for protection and its two states are\nread only or read/write.  Thus, write only is not supported in h/w.\n\nCurrently, if i \u0027mmap\u0027 a page write-only, the first read attempt on that page\ncreates a page fault and will SEGV.  That check is enforced in\narch/blah/mm/fault.c.  However, if i first write that page it will fault in\nand the pte will be set to read/write.  Thus, any subsequent reads to the page\nwill succeed.  It is this inconsistency in behavior that this patch is\nattempting to address.  Furthermore, if the page is swapped out, and then\nbrought back the first read will also cause a SEGV.  Thus, any arbitrary read\non a page can potentially result in a SEGV.\n\nAccording to the SuSv3 spec, \"if the application requests only PROT_WRITE, the\nimplementation may also allow read access.\" Also as mentioned, some\narchtectures, such as alpha, shown above already take the approach that i am\nsuggesting.\n\nThe counter-argument to this raised by Arjan, is that the kernel is enforcing\nthe write only mapping the best it can given the h/w limitations.  This is\ntrue, however Alan Cox, and myself would argue that the inconsitency in\nbehavior, that is applications can sometimes work/sometimes fails is highly\nundesireable.  If you read through the thread, i think people, came to an\nagreement on the last patch i posted, as nobody has objected to it...\n\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: Geert Uytterhoeven \u003cgeert@linux-m68k.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nAcked-by: Andi Kleen \u003cak@muc.de\u003e\nAcked-by: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Kazumoto Kojima \u003ckkojima@rr.iij4u.or.jp\u003e\nCc: Ian Molton \u003cspyro@f2s.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This array is used by NODE_DATA() macro.  When\nnew node is hot-added, this pgdat\u0027s array should be updated and copied on\nnew node too.\n\nHowever, I used for_each_online_node() in scatter_node_data() to copy\nit. This meant its array is not copied on new node.\nBecause initialization of structures for new node was halfway,\nso online_node_map couldn\u0027t be set at this time.\n\nTo copy arrays on new node, I changed it to check value of pgdat_list[]\nwhich is source array of copies.

      "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"

What appears to be a problem coming from flush_tlb_range(),\nwhich currently unconditionally calls platform_global_tlb_purge().\nFor some of the numa machines in existence today, this function is\nmapped into ia64_global_tlb_purge(), which holds ptcg_lock spin lock\nwhile executing ptc.ga instruction.\n\nHere is a patch that attempt to avoid global tlb purge whenever\npossible.  It will use local tlb purge as much as possible. Though the\nconditions to use local tlb purge is pretty restrictive.  One of the\nside effect of having flush tlb range instruction on ia64 is that\nkernel don\u0027t get a chance to clear out cpu_vm_mask.  On ia64, this mask\nis sticky and it will accumulate if process bounces around.  Thus\ndiminishing the possible use of ptc.l.

      "message": "[PATCH] hugepage: is_aligned_hugepage_range() cleanup\n\nQuite a long time back, prepare_hugepage_range() replaced\nis_aligned_hugepage_range() as the callback from mm/mmap.c to arch code to\nverify if an address range is suitable for a hugepage mapping.\nis_aligned_hugepage_range() stuck around, but only to implement\nprepare_hugepage_range() on archs which didn\u0027t implement their own.\n\nMost archs (everything except ia64 and powerpc) used the same\nimplementation of is_aligned_hugepage_range().  On powerpc, which\nimplements its own prepare_hugepage_range(), the custom version was never\nused.\n\nIn addition, \"is_aligned_hugepage_range()\" was a bad name, because it\nsuggests it returns true iff the given range is a good hugepage range,\nwhereas in fact it returns 0-or-error (so the sense is reversed).\n\nThis patch cleans up by abolishing is_aligned_hugepage_range().  Instead\nprepare_hugepage_range() is defined directly.  Most archs use the default\nversion, which simply checks the given region is aligned to the size of a\nhugepage.  ia64 and powerpc define custom versions.  The ia64 one simply\nchecks that the range is in the correct address space region in addition to\nbeing suitably aligned.  The powerpc version (just as previously) checks\nfor suitable addresses, and if necessary performs low-level MMU frobbing to\nset up new areas for use by hugepages.\n\nNo libhugetlbfs testsuite regressions on ppc64 (POWER5 LPAR).\n\nSigned-off-by: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nSigned-off-by: Zhang Yanmin \u003cyanmin.zhang@intel.com\u003e\nCc: \"David S.

However, they are all included for completeness.  This\nshould also make any future consolidation of all of the implementations a\nlittle more straightforward.\n\nThis lock is also held in the sparsemem code during a memory removal, as\nsections are invalidated.

Others required a deeper audit: I could find no reliance on\npage_table_lock in any; but in ia64 and parisc found some code which looks a\nbit as if it might want preemption disabled.  That won\u0027t do any actual harm,\nso pending a decision from the maintainers, disable preemption there.\n\nRemove comments on page_table_lock from flush_tlb_mm, flush_tlb_range and\nflush_tlb_page entries in cachetlb.txt: they were rather misleading (what\ngeneric code does is different from what usually happens), the rules are now\nchanging, and it\u0027s not yet clear where we\u0027ll end up (will the generic\ntlb_flush_mmu happen always under lock?  never under lock?  or sometimes under\nand sometimes not?).\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"

      "message": "[PATCH] mm: init_mm without ptlock\n\nFirst step in pushing down the page_table_lock.  init_mm.page_table_lock has\nbeen used throughout the architectures (usually for ioremap): not to serialize\nkernel address space allocation (that\u0027s usually vmlist_lock), but because\npud_alloc,pmd_alloc,pte_alloc_kernel expect caller holds it.\n\nReverse that: don\u0027t lock or unlock init_mm.page_table_lock in any of the\narchitectures; instead rely on pud_alloc,pmd_alloc,pte_alloc_kernel to take\nand drop it when allocating a new one, to check lest a racing task already\ndid.  Similarly no page_table_lock in vmalloc\u0027s map_vm_area.\n\nSome temporary ugliness in __pud_alloc and __pmd_alloc: since they also handle\nuser mms, which are converted only by a later patch, for now they have to lock\ndifferently according to whether or not it\u0027s init_mm.\n\nIf sources get muddled, there\u0027s a danger that an arch source taking\ninit_mm.page_table_lock will be mixed with common source also taking it (or\nneither take it).  So break the rules and make another change, which should\nbreak the build for such a mismatch: remove the redundant mm arg from\npte_alloc_kernel (ppc64 scrapped its distinct ioremap_mm in 2.6.13).\n\nExceptions: arm26 used pte_alloc_kernel on user mm, now pte_alloc_map; ia64\nused pte_alloc_map on init_mm, now pte_alloc_kernel; parisc had bad args to\npmd_alloc and pte_alloc_kernel in unused USE_HPPA_IOREMAP code; ppc64\nmap_io_page forgot to unlock on failure; ppc mmu_mapin_ram and ppc64 im_free\ntook page_table_lock for no good reason.\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"
