We then trap on first write and call\nset_page_dirty() on the page, after which we map the page RW and\ncontinue execution.\n\nWhen we launder dirty pages, we call clear_page_dirty_for_io() which\nclears both the dirty flag, and maps the page RO again before we start\nwriteout so that the story can repeat itself.\n\nvma_wants_writenotify() excludes VM_PFNMAP on the basis that we cannot\ndo the regular dirty page stuff on raw PFNs and the memory isn\u0027t going\nanywhere anyway.\n\nThe recently introduced VM_MIXEDMAP mixes both !pfn_valid() and\npfn_valid() pages in a single mapping.\n\nWe can\u0027t do dirty page accounting on !pfn_valid() pages as stated\nabove, and mapping them RO causes them to be COW\u0027ed on write, which\nbreaks VM_SHARED semantics.\n\nExcluding VM_MIXEDMAP in vma_wants_writenotify() would mean we don\u0027t do\nthe regular dirty page accounting for the pfn_valid() pages, which\nwould bring back all the head-aches from inaccurate dirty page\naccounting.\n\nSo instead, we let the !pfn_valid() pages get mapped RO, but fix them\nup unconditionally in the fault path.\n\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nAcked-by: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: \"Jared Hulbert\" \u003cjaredeh@gmail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

This has the effect of marking the pte as non-present,\nwhich will prevent the hardware from updating its state.  When the new\nvalue is written back, the pte will be present again, and the hardware\ncan resume updating the access/dirty flags.\n\nWhen running in a virtualized environment, pagetable updates are\nrelatively expensive, since they generally involve some trap into the\nhypervisor.  To mitigate the cost of these updates, we tend to batch\nthem.\n\nHowever, because of the atomic nature of ptep_get_and_clear(), it is\ninherently non-batchable.  This new interface allows batching by\ngiving the underlying implementation enough information to open a\ntransaction between the read and write phases:\n\nptep_modify_prot_start() returns the current pte value, and puts the\n  pte entry into a state where either the hardware will not update the\n  pte, or if it does, the updates will be preserved on commit.\n\nptep_modify_prot_commit() writes back the updated pte, makes sure that\n  any hardware updates made since ptep_modify_prot_start() are\n  preserved.\n\nptep_modify_prot_start() and _commit() must be exactly paired, and\nused while holding the appropriate pte lock.  They do not protect\nagainst other software updates of the pte in any way.\n\nThe current implementations of ptep_modify_prot_start and _commit are\nfunctionally unchanged from before: _start() uses ptep_get_and_clear()\nfetch the pte and zero the entry, preventing any hardware updates.\n_commit() simply writes the new pte value back knowing that the\nhardware has not updated the pte in the meantime.\n\nThe only current user of this interface is mprotect\n\nSigned-off-by: Jeremy Fitzhardinge \u003cjeremy.fitzhardinge@citrix.com\u003e\nAcked-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nAcked-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n"

The error is arbitrarily picked to be\nEFAULT, since that was what get_user_pages() already used for the\nequivalent IO-mapped page case.\n\n[ Also removed an impossible test for pte_offset_map_lock() failing:\n  that\u0027s not how that function works ]\n\nAcked-by: Oleg Nesterov \u003coleg@tv-sign.ru\u003e\nAcked-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Roland McGrath \u003croland@redhat.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

Otherwise the page struct\n\treference that was returned may have PageReserved() set\n\tto indicate that it is not a valid page.\n\nAs discussed further in the thread, virt_addr_valid() is the preferable\nway to validate the object pointer in this case. In addition to fixing\nup the reserved page case, it also has the benefit of encapsulating the\nhack introduced by commit 4016a1390d07f15b267eecb20e76a48fd5c524ef on\nthe impacted platforms, allowing us to get rid of the extra checking in\nkobjsize() for the platforms that don\u0027t perform this type of bizarre\nmemory_end abuse (every nommu platform that isn\u0027t blackfin). If blackfin\ndecides to get in line with every other platform and use PageReserved\nfor the DMA pages in question, kobjsize() will also continue to work\nfine.\n\nIt also turns out that compound_order() will give us back 0-order for\nnon-head pages, so we can get rid of the PageCompound check and just\nuse compound_order() directly.

      "message": "fix SMP data race in pagetable setup vs walking\n\nThere is a possible data race in the page table walking code. After the split\nptlock patches, it actually seems to have been introduced to the core code, but\neven before that I think it would have impacted some architectures (powerpc\nand sparc64, at least, walk the page tables without taking locks eg. see\nfind_linux_pte()).\n\nThe race is as follows:\nThe pte page is allocated, zeroed, and its struct page gets its spinlock\ninitialized. The mm-wide ptl is then taken, and then the pte page is inserted\ninto the pagetables.\n\nAt this point, the spinlock is not guaranteed to have ordered the previous\nstores to initialize the pte page with the subsequent store to put it in the\npage tables. So another Linux page table walker might be walking down (without\nany locks, because we have split-leaf-ptls), and find that new pte we\u0027ve\ninserted. It might try to take the spinlock before the store from the other\nCPU initializes it. And subsequently it might read a pte_t out before stores\nfrom the other CPU have cleared the memory.\n\nThere are also similar races in higher levels of the page tables. They\nobviously don\u0027t involve the spinlock, but could see uninitialized memory.\n\nArch code and hardware pagetable walkers that walk the pagetables without\nlocks could see similar uninitialized memory problems, regardless of whether\nsplit ptes are enabled or not.\n\nI prefer to put the barriers in core code, because that\u0027s where the higher\nlevel logic happens, but the page table accessors are per-arch, and open-coding\nthem everywhere I don\u0027t think is an option. I\u0027ll put the read-side barriers\nin alpha arch code for now (other architectures perform data-dependent loads\nin order).\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

It was the wrong way round: we shouldn\u0027t\nweaken every pmd_bad and pud_bad check to let huge pages slip through - in\npart they check that we _don\u0027t_ have a huge page where it\u0027s not expected.\n\nPut the x86 pmd_bad() and pud_bad() definitions back to what they have long\nbeen: they can be improved (x86_32 should use PTE_MASK, to stop PAE thinking\njunk in the upper word is good; and x86_64 should follow x86_32\u0027s stricter\ncomparison, to stop thinking any subset of required bits is good); but that\nshould be a later patch.\n\nFix Hans\u0027 good observation that follow_page() will never find pmd_huge()\nbecause that would have already failed the pmd_bad test: test pmd_huge in\nbetween the pmd_none and pmd_bad tests.  Tighten x86\u0027s pmd_huge() check?\nNo, once it\u0027s a hugepage entry, it can get quite far from a good pmd: for\nexample, PROT_NONE leaves it with only ACCESSED of the KERN_PGTABLE bits.\n\nHowever... though follow_page() contains this and another test for huge\npages, so it\u0027s nice to keep it working on them, where does it actually get\ncalled on a huge page?  get_user_pages() checks is_vm_hugetlb_page(vma) to\nto call alternative hugetlb processing, as does unmap_vmas() and others.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nEarlier-version-tested-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Jeff Chua \u003cjeff.chua.linux@gmail.com\u003e\nCc: Hans Rosenfeld \u003chans.rosenfeld@amd.com\u003e\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

If a section has usemap, it can\u0027t be removed until removing\n    other sections.  This dependency is not desirable for memory removing.\n\n    Pgdat has similar feature.  When a section has pgdat area, it must be the last\n    section for removing on the node.  So, if section A has pgdat and section B\n    has usemap for section A, Both sections can\u0027t be removed due to dependency\n    each other.\n\n    To solve this issue, this patch collects usemap on same section with pgdat.\n    If other sections doesn\u0027t have any dependency, this section will be able to be\n    removed finally.\n\n    Signed-off-by: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\n    Cc: Badari Pulavarty \u003cpbadari@us.ibm.com\u003e\n    Cc: Yinghai Lu \u003cyhlu.kernel@gmail.com\u003e\n    Cc: Yasunori Goto \u003cy-goto@jp.fujitsu.com\u003e\n    Signed-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n    Signed-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n\nbroke davem\u0027s sparc64 bootup.

      "message": "infrastructure to debug (dynamic) objects\n\nWe can see an ever repeating problem pattern with objects of any kind in the\nkernel:\n\n1) freeing of active objects\n2) reinitialization of active objects\n\nBoth problems can be hard to debug because the crash happens at a point where\nwe have no chance to decode the root cause anymore.  One problem spot are\nkernel timers, where the detection of the problem often happens in interrupt\ncontext and usually causes the machine to panic.\n\nWhile working on a timer related bug report I had to hack specialized code\ninto the timer subsystem to get a reasonable hint for the root cause.  This\ndebug hack was fine for temporary use, but far from a mergeable solution due\nto the intrusiveness into the timer code.\n\nThe code further lacked the ability to detect and report the root cause\ninstantly and keep the system operational.\n\nKeeping the system operational is important to get hold of the debug\ninformation without special debugging aids like serial consoles and special\nknowledge of the bug reporter.\n\nThe problems described above are not restricted to timers, but timers tend to\nexpose it usually in a full system crash.  Other objects are less explosive,\nbut the symptoms caused by such mistakes can be even harder to debug.\n\nInstead of creating specialized debugging code for the timer subsystem a\ngeneric infrastructure is created which allows developers to verify their code\nand provides an easy to enable debug facility for users in case of trouble.\n\nThe debugobjects core code keeps track of operations on static and dynamic\nobjects by inserting them into a hashed list and sanity checking them on\nobject operations and provides additional checks whenever kernel memory is\nfreed.\n\nThe tracked object operations are:\n- initializing an object\n- adding an object to a subsystem list\n- deleting an object from a subsystem list\n\nEach operation is sanity checked before the operation is executed and the\nsubsystem specific code can provide a fixup function which allows to prevent\nthe damage of the operation.  When the sanity check triggers a warning message\nand a stack trace is printed.\n\nThe list of operations can be extended if the need arises.  For now it\u0027s\nlimited to the requirements of the first user (timers).\n\nThe core code enqueues the objects into hash buckets.  The hash index is\ngenerated from the address of the object to simplify the lookup for the check\non kfree/vfree.  Each bucket has it\u0027s own spinlock to avoid contention on a\nglobal lock.\n\nThe debug code can be compiled in without being active.  The runtime overhead\nis minimal and could be optimized by asm alternatives.  A kernel command line\noption enables the debugging code.\n\nThanks to Ingo Molnar for review, suggestions and cleanup patches.\n\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Greg KH \u003cgreg@kroah.com\u003e\nCc: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nCc: Kay Sievers \u003ckay.sievers@vrfy.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
