Some of the fallout of review (DeviceTree support, multi-platform-\n      image support) were added on top of orig series, primarily to\n      record the revision history.\n\n  This updated pull request additionally contains\n\n   - fixes due to our GNU tools catching up with the new syscall/ptrace\n     ABI\n\n   - some (minor) cross-arch Kconfig updates.\"\n\n* tag \u0027arc-v3.9-rc1-late\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: (82 commits)\n  ARC: split elf.h into uapi and export it for userspace\n  ARC: Fixup the current ABI version\n  ARC: gdbserver using regset interface possibly broken\n  ARC: Kconfig cleanup tracking cross-arch Kconfig pruning in merge window\n  ARC: make a copy of flat DT\n  ARC: [plat-arcfpga] DT arc-uart bindings change: \"baud\" \u003d\u003e \"current-speed\"\n  ARC: Ensure CONFIG_VIRT_TO_BUS is not enabled\n  ARC: Fix pt_orig_r8 access\n  ARC: [3.9] Fallout of hlist iterator update\n  ARC: 64bit RTSC timestamp hardware issue\n  ARC: Don\u0027t fiddle with non-existent caches\n  ARC: Add self to MAINTAINERS\n  ARC: Provide a default serial.h for uart drivers needing BASE_BAUD\n  ARC: [plat-arcfpga] defconfig for fully loaded ARC Linux\n  ARC: [Review] Multi-platform image #8: platform registers SMP callbacks\n  ARC: [Review] Multi-platform image #7: SMP common code to use callbacks\n  ARC: [Review] Multi-platform image #6: cpu-to-dma-addr optional\n  ARC: [Review] Multi-platform image #5: NR_IRQS defined by ARC core\n  ARC: [Review] Multi-platform image #4: Isolate platform headers\n  ARC: [Review] Multi-platform image #3: switch to board callback\n  ...\n"

This performs pretty\n  much like CONFIG_VIRT_CPU_ACCOUNTING except that context location\n  and cputime snaphots are synchronized between write and read\n  side such that the latter can safely retrieve the pending tickless\n  cputime of a task and add it to its latest cputime snapshot to\n  return the correct result to the user.\"\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n"

      "message": "efi: Make \u0027efi_enabled\u0027 a function to query EFI facilities\n\nOriginally \u0027efi_enabled\u0027 indicated whether a kernel was booted from\nEFI firmware. Over time its semantics have changed, and it now\nindicates whether or not we are booted on an EFI machine with\nbit-native firmware, e.g. 64-bit kernel with 64-bit firmware.\n\nThe immediate motivation for this patch is the bug report at,\n\n    https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557\n\nwhich details how running a platform driver on an EFI machine that is\ndesigned to run under BIOS can cause the machine to become\nbricked. Also, the following report,\n\n    https://bugzilla.kernel.org/show_bug.cgi?id\u003d47121\n\ndetails how running said driver can also cause Machine Check\nExceptions. Drivers need a new means of detecting whether they\u0027re\nrunning on an EFI machine, as sadly the expression,\n\n    if (!efi_enabled)\n\nhasn\u0027t been a sufficient condition for quite some time.\n\nUsers actually want to query \u0027efi_enabled\u0027 for different reasons -\nwhat they really want access to is the list of available EFI\nfacilities.\n\nFor instance, the x86 reboot code needs to know whether it can invoke\nthe ResetSystem() function provided by the EFI runtime services, while\nthe ACPI OSL code wants to know whether the EFI config tables were\nmapped successfully. There are also checks in some of the platform\ndriver code to simply see if they\u0027re running on an EFI machine (which\nwould make it a bad idea to do BIOS-y things).\n\nThis patch is a prereq for the samsung-laptop fix patch.\n\nCc: David Airlie \u003cairlied@linux.ie\u003e\nCc: Corentin Chary \u003ccorentincj@iksaif.net\u003e\nCc: Matthew Garrett \u003cmjg59@srcf.ucam.org\u003e\nCc: Dave Jiang \u003cdave.jiang@intel.com\u003e\nCc: Olof Johansson \u003colof@lixom.net\u003e\nCc: Peter Jones \u003cpjones@redhat.com\u003e\nCc: Colin Ian King \u003ccolin.king@canonical.com\u003e\nCc: Steve Langasek \u003csteve.langasek@canonical.com\u003e\nCc: Tony Luck \u003ctony.luck@intel.com\u003e\nCc: Konrad Rzeszutek Wilk \u003ckonrad@kernel.org\u003e\nCc: Rafael J.

      "message": "memcg: infrastructure to match an allocation to the right cache\n\nThe page allocator is able to bind a page to a memcg when it is\nallocated.  But for the caches, we\u0027d like to have as many objects as\npossible in a page belonging to the same cache.\n\nThis is done in this patch by calling memcg_kmem_get_cache in the\nbeginning of every allocation function.  This function is patched out by\nstatic branches when kernel memory controller is not being used.\n\nIt assumes that the task allocating, which determines the memcg in the\npage allocator, belongs to the same cgroup throughout the whole process.\nMisaccounting can happen if the task calls memcg_kmem_get_cache() while\nbelonging to a cgroup, and later on changes.  This is considered\nacceptable, and should only happen upon task migration.\n\nBefore the cache is created by the memcg core, there is also a possible\nimbalance: the task belongs to a memcg, but the cache being allocated from\nis the global cache, since the child cache is not yet guaranteed to be\nready.  This case is also fine, since in this case the GFP_KMEMCG will not\nbe passed and the page allocator will not attempt any cgroup accounting.\n\nSigned-off-by: Glauber Costa \u003cglommer@parallels.com\u003e\nCc: Christoph Lameter \u003ccl@linux.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@redhat.com\u003e\nCc: Greg Thelen \u003cgthelen@google.com\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: JoonSoo Kim \u003cjs1304@gmail.com\u003e\nCc: KAMEZAWA Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Michal Hocko \u003cmhocko@suse.cz\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Suleiman Souhlal \u003csuleiman@google.com\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

They\nreflect the state of the \"kmem\" res_counter.\n\nPer cgroup kmem memory accounting is not enabled until a limit is set for\nthe group.  Once the limit is set the accounting cannot be disabled for\nthat group.  This means that after the patch is applied, no behavioral\nchanges exists for whoever is still using memcg to control their memory\nusage, until memory.kmem.limit_in_bytes is set for the first time.\n\nWe always account to both user and kernel resource_counters.  This\neffectively means that an independent kernel limit is in place when the\nlimit is set to a lower value than the user memory.  A equal or higher\nvalue means that the user limit will always hit first, meaning that kmem\nis effectively unlimited.\n\nPeople who want to track kernel memory but not limit it, can set this\nlimit to a very high number (like RESOURCE_MAX - 1page - that no one will\never hit, or equal to the user memory)\n\n[akpm@linux-foundation.org: MEMCG_MMEM only works with slab and slub]\nSigned-off-by: Glauber Costa \u003cglommer@parallels.com\u003e\nAcked-by: Kamezawa Hiroyuki \u003ckamezawa.hiroyu@jp.fujitsu.com\u003e\nAcked-by: Michal Hocko \u003cmhocko@suse.cz\u003e\nCc: Johannes Weiner \u003channes@cmpxchg.org\u003e\nCc: Tejun Heo \u003ctj@kernel.org\u003e\nCc: Christoph Lameter \u003ccl@linux.com\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@redhat.com\u003e\nCc: Greg Thelen \u003cgthelen@google.com\u003e\nCc: JoonSoo Kim \u003cjs1304@gmail.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

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"

      "message": "rcu: Add callback-free CPUs\n\nRCU callback execution can add significant OS jitter and also can\ndegrade both scheduling latency and, in asymmetric multiprocessors,\nenergy efficiency.  This commit therefore adds the ability for selected\nCPUs (\"rcu_nocbs\u003d\" boot parameter) to have their callbacks offloaded\nto kthreads.  If the \"rcu_nocb_poll\" boot parameter is also specified,\nthese kthreads will do polling, removing the need for the offloaded\nCPUs to do wakeups.
