An async\nworker, upon being woken up, fetches the first item from the pending\nlist, which kept the executing lists sorted. The conversion to\nworkqueue was done by adding work_struct to each async_entry and async\njust schedules the work item. The queueing and dispatching of such work\nitems are still in order but now each worker thread is associated with a\nspecific async_entry and moves that specific async_entry to the\nexecuting list. So, depending on which worker reaches that point\nearlier, which is non-deterministic, we may end up moving an async_entry\nwith larger cookie before one with smaller one.\n\nThis broke __lowest_in_progress(). running-\u003edomain may not be properly\nsorted and is not guaranteed to contain lower cookies than pending list\nwhen not empty. Fix it by ensuring sort-inserting to the running list\nand always looking at both pending and running when trying to determine\nthe lowest cookie.\n\nOver time, the async synchronization implementation became quite messy.\nWe better restructure it such that each async_entry is linked to two\nlists - one global and one per domain - and not move it when execution\nstarts.

If it\u0027s disabled then\nit does not start the tracer internals.\n\nThe problem is that writing \"1\" into tracing_on does not call the\ntracers \"start\" routine like writing \"1\" into tracing_enabled did.\nThis makes the irqsoff tracer not start when using the trace-cmd\ntool, and is a regression for userspace.\n\nSimple fix is to have the tracing_on file call the tracers start()\nmethod when being enabled (and the stop() method when disabled).\n\nSigned-off-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\n" }, { "commit": "bfbbd96c51b441b7a9a08762aa9ab832f6655b2c", "tree": "ec27b53bd370898cb198846d5ff324e185987261", "parents": [ "7144bca6814a79ac86800da9d7f05a8c07bc818c" ], "author": { "name": "Randy Dunlap", "email": "rdunlap@infradead.org", "time": "Wed Jan 09 17:12:45 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 10 14:35:23 2013 -0800" }, "message": "audit: fix auditfilter.c kernel-doc warnings\n\nFix new kernel-doc warning in auditfilter.c:\n\n Warning(kernel/auditfilter.c:1157): Excess function parameter \u0027uid\u0027 description in \u0027audit_receive_filter\u0027\n\nSigned-off-by: Randy Dunlap \u003crdunlap@infradead.org\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Eric Paris \u003ceparis@redhat.com\u003e\nCc: linux-audit@redhat.com (subscribers-only)\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "4ffd4ebf9d19c07285ea8a26d30a17ff28767132", "tree": "d563023f1764aac5c5232315c356fa258f53dcce", "parents": [ "7be72c39544e3973509f1c299d255a67177c7a33", "a8dd2176a8e988e3744e863ac39647a6f59fa900" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 10 09:03:16 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jan 10 09:03:16 2013 -0800" }, "message": "Merge tag \u0027trace-3.8-rc2-regression-fix\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace\n\nPull tracing regression fix from Steven Rostedt:\n \"A change that came in this merge window broke the writing to the\n trace_options file.

In the interest of getting the ball rolling, it would be\n desirable to see this much merged for 3.8 with the view to building\n scheduler smarts on top and adapting the VM where required for 3.9.\n\n The most recent set of comparisons available from different people are\n\n mel: https://lkml.org/lkml/2012/12/9/108\n mingo: https://lkml.org/lkml/2012/12/7/331\n tglx: https://lkml.org/lkml/2012/12/10/437\n srikar: https://lkml.org/lkml/2012/12/10/397\n\n The results are a mixed bag. In my own tests, balancenuma does\n reasonably well. It\u0027s dumb as rocks and does not regress against\n mainline. On the other hand, Ingo\u0027s tests shows that balancenuma is\n incapable of converging for this workloads driven by perf which is bad\n but is potentially explained by the lack of scheduler smarts. Thomas\u0027\n results show balancenuma improves on mainline but falls far short of\n numacore or autonuma. Srikar\u0027s results indicate we all suffer on a\n large machine with imbalanced node sizes.\n\n My own testing showed that recent numacore results have improved\n dramatically, particularly in the last week but not universally.\n We\u0027ve butted heads heavily on system CPU usage and high levels of\n migration even when it shows that overall performance is better.\n There are also cases where it regresses. Of interest is that for\n specjbb in some configurations it will regress for lower numbers of\n warehouses and show gains for higher numbers which is not reported by\n the tool by default and sometimes missed in treports. Recently I\n reported for numacore that the JVM was crashing with\n NullPointerExceptions but currently it\u0027s unclear what the source of\n this problem is. Initially I thought it was in how numacore batch\n handles PTEs but I\u0027m no longer think this is the case. It\u0027s possible\n numacore is just able to trigger it due to higher rates of migration.\n\n These reports were quite late in the cycle so I/we would like to start\n with this tree as it contains much of the code we can agree on and has\n not changed significantly over the last 2-3 weeks.\"\n\n* tag \u0027balancenuma-v11\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux-balancenuma: (50 commits)\n mm/rmap, migration: Make rmap_walk_anon() and try_to_unmap_anon() more scalable\n mm/rmap: Convert the struct anon_vma::mutex to an rwsem\n mm: migrate: Account a transhuge page properly when rate limiting\n mm: numa: Account for failed allocations and isolations as migration failures\n mm: numa: Add THP migration for the NUMA working set scanning fault case build fix\n mm: numa: Add THP migration for the NUMA working set scanning fault case.\n mm: sched: numa: Delay PTE scanning until a task is scheduled on a new node\n mm: sched: numa: Control enabling and disabling of NUMA balancing if !SCHED_DEBUG\n mm: sched: numa: Control enabling and disabling of NUMA balancing\n mm: sched: Adapt the scanning rate if a NUMA hinting fault does not migrate\n mm: numa: Use a two-stage filter to restrict pages being migrated for unlikely task\u003c-\u003enode relationships\n mm: numa: migrate: Set last_nid on newly allocated page\n mm: numa: split_huge_page: Transfer last_nid on tail page\n mm: numa: Introduce last_nid to the page frame\n sched: numa: Slowly increase the scanning period as NUMA faults are handled\n mm: numa: Rate limit setting of pte_numa if node is saturated\n mm: numa: Rate limit the amount of memory that is migrated between nodes\n mm: numa: Structures for Migrate On Fault per NUMA migration rate limiting\n mm: numa: Migrate pages handled during a pmd_numa hinting fault\n mm: numa: Migrate on reference policy\n ...\n" }, { "commit": "1ed55eac3b1fc30b29cdb52251e0f13b24fc344c", "tree": "b7a4c67f2e29f8aa418708c5da871e64c511f3ff", "parents": [ "08242bc2210938761230f79c5288dbcf72e94808", "a2c0911c09190125f52c9941b9d187f601c2f7be" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Dec 15 12:35:19 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Dec 15 12:35:19 2012 -0800" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6\n\nPull crypto update from Herbert Xu:\n\n - Added aesni/avx/x86_64 implementations for camellia.\n\n - Optimised AVX code for cast5/serpent/twofish/cast6.\n\n - Fixed vmac bug with unaligned input.\n\n - Allow compression algorithms in FIPS mode.\n\n - Optimised crc32c implementation for Intel.\n\n - Misc fixes.\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (32 commits)\n crypto: caam - Updated SEC-4.0 device tree binding for ERA information.\n crypto: testmgr - remove superfluous initializers for xts(aes)\n crypto: testmgr - allow compression algs in fips mode\n crypto: testmgr - add larger crc32c test vector to test FPU path in crc32c_intel\n crypto: testmgr - clean alg_test_null entries in alg_test_descs[]\n crypto: testmgr - remove fips_allowed flag from camellia-aesni null-tests\n crypto: cast5/cast6 - move lookup tables to shared module\n padata: use __this_cpu_read per-cpu helper\n crypto: s5p-sss - Fix compilation error\n crypto: picoxcell - Add terminating entry for platform_device_id table\n crypto: omap-aes - select BLKCIPHER2\n crypto: camellia - add AES-NI/AVX/x86_64 assembler implementation of camellia cipher\n crypto: camellia-x86_64 - share common functions and move structures and function definitions to header file\n crypto: tcrypt - add async speed test for camellia cipher\n crypto: tegra-aes - fix error-valued pointer dereference\n crypto: tegra - fix missing unlock on error case\n crypto: cast5/avx - avoid using temporary stack buffers\n crypto: serpent/avx - avoid using temporary stack buffers\n crypto: twofish/avx - avoid using temporary stack buffers\n crypto: cast6/avx - avoid using temporary stack buffers\n ...\n" }, { "commit": "5155040ed349950e16c093ba8e65ad534994df2a", "tree": "2b58aab3a6c1a6f42c0716e0c4bb60e86188bb80", "parents": [ "aa6d054e5ce94720797ca260392a74dbced56412" ], "author": { "name": "Eric W.

Since the init_module syscall hands the kernel a module\nas a memory blob, no reasoning about the origin of the blob can be made.\n\nEarlier proposals for appending signatures to kernel modules would not be\nuseful in Chrome OS, since it would involve adding an additional set of\nkeys to our kernel and builds for no good reason: we already trust the\ncontents of our root filesystem. We don\u0027t need to verify those kernel\nmodules a second time. Having to do signature checking on module loading\nwould slow us down and be redundant. All we need to know is where a\nmodule is coming from so we can say yes/no to loading it.\n\nIf a file descriptor is used as the source of a kernel module, many more\nthings can be reasoned about. In Chrome OS\u0027s case, we could enforce that\nthe module lives on the filesystem we expect it to live on. In the case\nof IMA (or other LSMs), it would be possible, for example, to examine\nextended attributes that may contain signatures over the contents of\nthe module.\n\nThis introduces a new syscall (on x86), similar to init_module, that has\nonly two arguments. The first argument is used as a file descriptor to\nthe module and the second argument is a pointer to the NULL terminated\nstring of module arguments.\n\nSigned-off-by: Kees Cook \u003ckeescook@chromium.org\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e (merge fixes)\n" }, { "commit": "66cdd0ceaf65a18996f561b770eedde1d123b019", "tree": "4892eaa422d366fce5d1e866ff1fe0988af95569", "parents": [ "896ea17d3da5f44b2625c9cda9874d7dfe447393", "58b7825bc324da55415034a9f6ca5d716b8fd898" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 13 15:31:08 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 13 15:31:08 2012 -0800" }, "message": "Merge tag \u0027kvm-3.8-1\u0027 of git://git.kernel.org/pub/scm/virt/kvm/kvm\n\nPull KVM updates from Marcelo Tosatti:\n \"Considerable KVM/PPC work, x86 kvmclock vsyscall support,\n IA32_TSC_ADJUST MSR emulation, amongst others.\"\n\nFix up trivial conflict in kernel/sched/core.c due to cross-cpu\nmigration notifier added next to rq migration call-back.\n\n* tag \u0027kvm-3.8-1\u0027 of git://git.kernel.org/pub/scm/virt/kvm/kvm: (156 commits)\n KVM: emulator: fix real mode segment checks in address linearization\n VMX: remove unneeded enable_unrestricted_guest check\n KVM: VMX: fix DPL during entry to protected mode\n x86/kexec: crash_vmclear_local_vmcss needs __rcu\n kvm: Fix irqfd resampler list walk\n KVM: VMX: provide the vmclear function and a bitmap to support VMCLEAR in kdump\n x86/kexec: VMCLEAR VMCSs loaded on all cpus if necessary\n KVM: MMU: optimize for set_spte\n KVM: PPC: booke: Get/set guest EPCR register using ONE_REG interface\n KVM: PPC: bookehv: Add EPCR support in mtspr/mfspr emulation\n KVM: PPC: bookehv: Add guest computation mode for irq delivery\n KVM: PPC: Make EPCR a valid field for booke64 and bookehv\n KVM: PPC: booke: Extend MAS2 EPN mask for 64-bit\n KVM: PPC: e500: Mask MAS2 EPN high 32-bits in 32/64 tlbwe emulation\n KVM: PPC: Mask ea\u0027s high 32-bits in 32/64 instr emulation\n KVM: PPC: e500: Add emulation helper for getting instruction ea\n KVM: PPC: bookehv64: Add support for interrupt handling\n KVM: PPC: bookehv: Remove GET_VCPU macro from exception handler\n KVM: PPC: booke: Fix get_tb() compile error on 64-bit\n KVM: PPC: e500: Silence bogus GCC warning in tlb code\n ...\n" }, { "commit": "f6e858a00af788bab0fd4c0b7f5cd788000edc18", "tree": "f9403ca3671be9821dbf83e726e61dbe75fbca6b", "parents": [ "193c0d682525987db59ac3a24531a77e4947aa95", "98870901cce098bbe94d90d2c41d8d1fa8d94392" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 13 13:11:15 2012 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Dec 13 13:11:15 2012 -0800" }, "message": "Merge branch \u0027akpm\u0027 (Andrew\u0027s patch-bomb)\n\nMerge misc VM changes from Andrew Morton:\n \"The rest of most-of-MM.
