      "message": "cgroup, memcg: move cgroup_event implementation to memcg\n\ncgroup_event is way over-designed and tries to build a generic\nflexible event mechanism into cgroup - fully customizable event\nspecification for each user of the interface.  This is utterly\nunnecessary and overboard especially in the light of the planned\nunified hierarchy as there\u0027s gonna be single agent.  Simply generating\nevents at fixed points, or if that\u0027s too restrictive, configureable\ncadence or single set of configureable points should be enough.\n\nThankfully, memcg is the only user and gets to keep it.  Replacing it\nwith something simpler on sane_behavior is strongly recommended.\n\nThis patch moves cgroup_event and \"cgroup.event_control\"\nimplementation to mm/memcontrol.c.  Clearing of events on cgroup\ndestruction is moved from cgroup_destroy_locked() to\nmem_cgroup_css_offline(), which shouldn\u0027t make any noticeable\ndifference.\n\ncgroup_css() and __file_cft() are exported to enable the move;\nhowever, this will soon be reverted once the event code is updated to\nbe memcg specific.\n\nNote that \"cgroup.event_control\" will now exist only on the hierarchy\nwith memcg attached to it.  While this change is visible to userland,\nit is unlikely to be noticeable as the file has never been meaningful\noutside memcg.\n\nAside from the above change, this is pure code relocation.\n\nv2: Per Li Zefan\u0027s comments, init/Kconfig updated accordingly and\n    poll.h inclusion moved from cgroup.c to memcontrol.c.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Li Zefan \u003clizefan@huawei.com\u003e\nAcked-by: Kirill A.

      "message": "Merge branch \u0027for-linus2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security\n\nPull security subsystem updates from James Morris:\n \"In this patchset, we finally get an SELinux update, with Paul Moore\n  taking over as maintainer of that code.\n\n  Also a significant update for the Keys subsystem, as well as\n  maintenance updates to Smack, IMA, TPM, and Apparmor\"\n\nand since I wanted to know more about the updates to key handling,\nhere\u0027s the explanation from David Howells on that:\n\n \"Okay.  There are a number of separate bits.  I\u0027ll go over the big bits\n  and the odd important other bit, most of the smaller bits are just\n  fixes and cleanups.  If you want the small bits accounting for, I can\n  do that too.\n\n   (1) Keyring capacity expansion.\n\n        KEYS: Consolidate the concept of an \u0027index key\u0027 for key access\n        KEYS: Introduce a search context structure\n        KEYS: Search for auth-key by name rather than target key ID\n        Add a generic associative array implementation.\n        KEYS: Expand the capacity of a keyring\n\n     Several of the patches are providing an expansion of the capacity of a\n     keyring.  Currently, the maximum size of a keyring payload is one page.\n     Subtract a small header and then divide up into pointers, that only gives\n     you ~500 pointers on an x86_64 box.  However, since the NFS idmapper uses\n     a keyring to store ID mapping data, that has proven to be insufficient to\n     the cause.\n\n     Whatever data structure I use to handle the keyring payload, it can only\n     store pointers to keys, not the keys themselves because several keyrings\n     may point to a single key.  This precludes inserting, say, and rb_node\n     struct into the key struct for this purpose.\n\n     I could make an rbtree of records such that each record has an rb_node\n     and a key pointer, but that would use four words of space per key stored\n     in the keyring.  It would, however, be able to use much existing code.\n\n     I selected instead a non-rebalancing radix-tree type approach as that\n     could have a better space-used/key-pointer ratio.  I could have used the\n     radix tree implementation that we already have and insert keys into it by\n     their serial numbers, but that means any sort of search must iterate over\n     the whole radix tree.  Further, its nodes are a bit on the capacious side\n     for what I want - especially given that key serial numbers are randomly\n     allocated, thus leaving a lot of empty space in the tree.\n\n     So what I have is an associative array that internally is a radix-tree\n     with 16 pointers per node where the index key is constructed from the key\n     type pointer and the key description.  This means that an exact lookup by\n     type+description is very fast as this tells us how to navigate directly to\n     the target key.\n\n     I made the data structure general in lib/assoc_array.c as far as it is\n     concerned, its index key is just a sequence of bits that leads to a\n     pointer.  It\u0027s possible that someone else will be able to make use of it\n     also.  FS-Cache might, for example.\n\n   (2) Mark keys as \u0027trusted\u0027 and keyrings as \u0027trusted only\u0027.\n\n        KEYS: verify a certificate is signed by a \u0027trusted\u0027 key\n        KEYS: Make the system \u0027trusted\u0027 keyring viewable by userspace\n        KEYS: Add a \u0027trusted\u0027 flag and a \u0027trusted only\u0027 flag\n        KEYS: Separate the kernel signature checking keyring from module signing\n\n     These patches allow keys carrying asymmetric public keys to be marked as\n     being \u0027trusted\u0027 and allow keyrings to be marked as only permitting the\n     addition or linkage of trusted keys.\n\n     Keys loaded from hardware during kernel boot or compiled into the kernel\n     during build are marked as being trusted automatically.  New keys can be\n     loaded at runtime with add_key().  They are checked against the system\n     keyring contents and if their signatures can be validated with keys that\n     are already marked trusted, then they are marked trusted also and can\n     thus be added into the master keyring.\n\n     Patches from Mimi Zohar make this usable with the IMA keyrings also.\n\n   (3) Remove the date checks on the key used to validate a module signature.\n\n        X.509: Remove certificate date checks\n\n     It\u0027s not reasonable to reject a signature just because the key that it was\n     generated with is no longer valid datewise - especially if the kernel\n     hasn\u0027t yet managed to set the system clock when the first module is\n     loaded - so just remove those checks.\n\n   (4) Make it simpler to deal with additional X.509 being loaded into the kernel.\n\n        KEYS: Load *.x509 files into kernel keyring\n        KEYS: Have make canonicalise the paths of the X.509 certs better to deduplicate\n\n     The builder of the kernel now just places files with the extension \".x509\"\n     into the kernel source or build trees and they\u0027re concatenated by the\n     kernel build and stuffed into the appropriate section.\n\n   (5) Add support for userspace kerberos to use keyrings.\n\n        KEYS: Add per-user_namespace registers for persistent per-UID kerberos caches\n        KEYS: Implement a big key type that can save to tmpfs\n\n     Fedora went to, by default, storing kerberos tickets and tokens in tmpfs.\n     We looked at storing it in keyrings instead as that confers certain\n     advantages such as tickets being automatically deleted after a certain\n     amount of time and the ability for the kernel to get at these tokens more\n     easily.\n\n     To make this work, two things were needed:\n\n     (a) A way for the tickets to persist beyond the lifetime of all a user\u0027s\n         sessions so that cron-driven processes can still use them.\n\n         The problem is that a user\u0027s session keyrings are deleted when the\n         session that spawned them logs out and the user\u0027s user keyring is\n         deleted when the UID is deleted (typically when the last log out\n         happens), so neither of these places is suitable.\n\n         I\u0027ve added a system keyring into which a \u0027persistent\u0027 keyring is\n         created for each UID on request.  Each time a user requests their\n         persistent keyring, the expiry time on it is set anew.  If the user\n         doesn\u0027t ask for it for, say, three days, the keyring is automatically\n         expired and garbage collected using the existing gc.  All the kerberos\n         tokens it held are then also gc\u0027d.\n\n     (b) A key type that can hold really big tickets (up to 1MB in size).\n\n         The problem is that Active Directory can return huge tickets with lots\n         of auxiliary data attached.  We don\u0027t, however, want to eat up huge\n         tracts of unswappable kernel space for this, so if the ticket is\n         greater than a certain size, we create a swappable shmem file and dump\n         the contents in there and just live with the fact we then have an\n         inode and a dentry overhead.  If the ticket is smaller than that, we\n         slap it in a kmalloc()\u0027d buffer\"\n\n* \u0027for-linus2\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: (121 commits)\n  KEYS: Fix keyring content gc scanner\n  KEYS: Fix error handling in big_key instantiation\n  KEYS: Fix UID check in keyctl_get_persistent()\n  KEYS: The RSA public key algorithm needs to select MPILIB\n  ima: define \u0027_ima\u0027 as a builtin \u0027trusted\u0027 keyring\n  ima: extend the measurement list to include the file signature\n  kernel/system_certificate.S: use real contents instead of macro GLOBAL()\n  KEYS: fix error return code in big_key_instantiate()\n  KEYS: Fix keyring quota misaccounting on key replacement and unlink\n  KEYS: Fix a race between negating a key and reading the error set\n  KEYS: Make BIG_KEYS boolean\n  apparmor: remove the \"task\" arg from may_change_ptraced_domain()\n  apparmor: remove parent task info from audit logging\n  apparmor: remove tsk field from the apparmor_audit_struct\n  apparmor: fix capability to not use the current task, during reporting\n  Smack: Ptrace access check mode\n  ima: provide hash algo info in the xattr\n  ima: enable support for larger default filedata hash algorithms\n  ima: define kernel parameter \u0027ima_template\u003d\u0027 to change configured default\n  ima: add Kconfig default measurement list template\n  ...\n"

      "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next\n\nPull networking updates from David Miller:\n\n 1) The addition of nftables.  No longer will we need protocol aware\n    firewall filtering modules, it can all live in userspace.\n\n    At the core of nftables is a, for lack of a better term, virtual\n    machine that executes byte codes to inspect packet or metadata\n    (arriving interface index, etc.) and make verdict decisions.\n\n    Besides support for loading packet contents and comparing them, the\n    interpreter supports lookups in various datastructures as\n    fundamental operations.  For example sets are supports, and\n    therefore one could create a set of whitelist IP address entries\n    which have ACCEPT verdicts attached to them, and use the appropriate\n    byte codes to do such lookups.\n\n    Since the interpreted code is composed in userspace, userspace can\n    do things like optimize things before giving it to the kernel.\n\n    Another major improvement is the capability of atomically updating\n    portions of the ruleset.  In the existing netfilter implementation,\n    one has to update the entire rule set in order to make a change and\n    this is very expensive.\n\n    Userspace tools exist to create nftables rules using existing\n    netfilter rule sets, but both kernel implementations will need to\n    co-exist for quite some time as we transition from the old to the\n    new stuff.\n\n    Kudos to Patrick McHardy, Pablo Neira Ayuso, and others who have\n    worked so hard on this.\n\n 2) Daniel Borkmann and Hannes Frederic Sowa made several improvements\n    to our pseudo-random number generator, mostly used for things like\n    UDP port randomization and netfitler, amongst other things.\n\n    In particular the taus88 generater is updated to taus113, and test\n    cases are added.\n\n 3) Support 64-bit rates in HTB and TBF schedulers, from Eric Dumazet\n    and Yang Yingliang.\n\n 4) Add support for new 577xx tigon3 chips to tg3 driver, from Nithin\n    Sujir.\n\n 5) Fix two fatal flaws in TCP dynamic right sizing, from Eric Dumazet,\n    Neal Cardwell, and Yuchung Cheng.\n\n 6) Allow IP_TOS and IP_TTL to be specified in sendmsg() ancillary\n    control message data, much like other socket option attributes.\n    From Francesco Fusco.\n\n 7) Allow applications to specify a cap on the rate computed\n    automatically by the kernel for pacing flows, via a new\n    SO_MAX_PACING_RATE socket option.  From Eric Dumazet.\n\n 8) Make the initial autotuned send buffer sizing in TCP more closely\n    reflect actual needs, from Eric Dumazet.\n\n 9) Currently early socket demux only happens for TCP sockets, but we\n    can do it for connected UDP sockets too.  Implementation from Shawn\n    Bohrer.\n\n10) Refactor inet socket demux with the goal of improving hash demux\n    performance for listening sockets.  With the main goals being able\n    to use RCU lookups on even request sockets, and eliminating the\n    listening lock contention.  From Eric Dumazet.\n\n11) The bonding layer has many demuxes in it\u0027s fast path, and an RCU\n    conversion was started back in 3.11, several changes here extend the\n    RCU usage to even more locations.  From Ding Tianhong and Wang\n    Yufen, based upon suggestions by Nikolay Aleksandrov and Veaceslav\n    Falico.\n\n12) Allow stackability of segmentation offloads to, in particular, allow\n    segmentation offloading over tunnels.  From Eric Dumazet.\n\n13) Significantly improve the handling of secret keys we input into the\n    various hash functions in the inet hashtables, TCP fast open, as\n    well as syncookies.  From Hannes Frederic Sowa.  The key fundamental\n    operation is \"net_get_random_once()\" which uses static keys.\n\n    Hannes even extended this to ipv4/ipv6 fragmentation handling and\n    our generic flow dissector.\n\n14) The generic driver layer takes care now to set the driver data to\n    NULL on device removal, so it\u0027s no longer necessary for drivers to\n    explicitly set it to NULL any more.  Many drivers have been cleaned\n    up in this way, from Jingoo Han.\n\n15) Add a BPF based packet scheduler classifier, from Daniel Borkmann.\n\n16) Improve CRC32 interfaces and generic SKB checksum iterators so that\n    SCTP\u0027s checksumming can more cleanly be handled.  Also from Daniel\n    Borkmann.\n\n17) Add a new PMTU discovery mode, IP_PMTUDISC_INTERFACE, which forces\n    using the interface MTU value.  This helps avoid PMTU attacks,\n    particularly on DNS servers.  From Hannes Frederic Sowa.\n\n18) Use generic XPS for transmit queue steering rather than internal\n    (re-)implementation in virtio-net.  From Jason Wang.\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1622 commits)\n  random32: add test cases for taus113 implementation\n  random32: upgrade taus88 generator to taus113 from errata paper\n  random32: move rnd_state to linux/random.h\n  random32: add prandom_reseed_late() and call when nonblocking pool becomes initialized\n  random32: add periodic reseeding\n  random32: fix off-by-one in seeding requirement\n  PHY: Add RTL8201CP phy_driver to realtek\n  xtsonic: add missing platform_set_drvdata() in xtsonic_probe()\n  macmace: add missing platform_set_drvdata() in mace_probe()\n  ethernet/arc/arc_emac: add missing platform_set_drvdata() in arc_emac_probe()\n  ipv6: protect for_each_sk_fl_rcu in mem_check with rcu_read_lock_bh\n  vlan: Implement vlan_dev_get_egress_qos_mask as an inline.\n  ixgbe: add warning when max_vfs is out of range.\n  igb: Update link modes display in ethtool\n  netfilter: push reasm skb through instead of original frag skbs\n  ip6_output: fragment outgoing reassembled skb properly\n  MAINTAINERS: mv643xx_eth: take over maintainership from Lennart\n  net_sched: tbf: support of 64bit rates\n  ixgbe: deleting dfwd stations out of order can cause null ptr deref\n  ixgbe: fix build err, num_rx_queues is only available with CONFIG_RPS\n  ...\n"

      "message": "modules: do not depend on kconfig to set \u0027modules\u0027 option to symbol MODULES\n\nCurrently, the MODULES symbol is special-cased in different places in the\nkconfig language. For example, if no symbol is defined to enable tristates,\nthen kconfig looks up for a symbol named \u0027MODULES\u0027, and forces the \u0027modules\u0027\noption onto that symbol.\n\nThis causes problems as such:\n  - since MODULES is special-cased, reading the configuration with\n    KCONFIG_ALLCONFIG set will forcibly set MODULES to be \u0027valid\u0027 (ie.\n    it has a valid value), when no such value was previously set. So\n    MODULES defaults to \u0027n\u0027 unless it is present in KCONFIG_ALLCONFIG\n  - other third-party projects may decide that \u0027MODULES\u0027 plays a different\n    role for them\n\nThis has been exposed by cset #cfa98f2e:\n    kconfig: do not override symbols already set\nand reported by Stephen in:\n    http://marc.info/?l\u003dlinux-next\u0026m\u003d137592137915234\u0026w\u003d2\n\nAs suggested by Sam, we explicitly define the MODULES symbol to be the\ntristate-enabler. This will allow us to drop special-casing of MODULES\nin the kconfig language, later.\n\n(Note: this patch is not a fix to Stephen\u0027s issue, just a first step).\n\nReported-by: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nSigned-off-by: yann.morin.1998@free.fr\nCc: Stephen Rothwell \u003csfr@canb.auug.org.au\u003e\nCc: Sam Ravnborg \u003csam@ravnborg.org\u003e\nCc: Michal Marek \u003cmmarek@suse.cz\u003e\nCc: Kevin Hilman \u003ckhilman@linaro.org\u003e\nCc: sedat.dilek@gmail.com\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\n"

      "message": "perf: Use hrtimers for event multiplexing\n\nThe current scheme of using the timer tick was fine for per-thread\nevents. However, it was causing bias issues in system-wide mode\n(including for uncore PMUs). Event groups would not get their fair\nshare of runtime on the PMU. With tickless kernels, if a core is idle\nthere is no timer tick, and thus no event rotation (multiplexing).\nHowever, there are events (especially uncore events) which do count\neven though cores are asleep.\n\nThis patch changes the timer source for multiplexing.  It introduces a\nper-PMU per-cpu hrtimer. The advantage is that even when a core goes\nidle, it will come back to service the hrtimer, thus multiplexing on\nsystem-wide events works much better.\n\nThe per-PMU implementation (suggested by PeterZ) enables adjusting the\nmultiplexing interval per PMU. The preferred interval is stashed into\nthe struct pmu. If not set, it will be forced to the default interval\nvalue.\n\nIn order to minimize the impact of the hrtimer, it is turned on and\noff on demand. When the PMU on a CPU is overcommited, the hrtimer is\nactivated.  It is stopped when the PMU is not overcommitted.\n\nIn order for this to work properly, we had to change the order of\ninitialization in start_kernel() such that hrtimer_init() is run\nbefore perf_event_init().\n\nThe default interval in milliseconds is set to a timer tick just like\nwith the old code. We will provide a sysctl to tune this in another\npatch.\n\nSigned-off-by: Stephane Eranian \u003ceranian@google.com\u003e\nSigned-off-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nLink: http://lkml.kernel.org/r/1364991694-5876-2-git-send-email-eranian@google.com\nSigned-off-by: Ingo Molnar \u003cmingo@kernel.org\u003e\n"

      "message": "Merge branch \u0027timers-nohz-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip\n\nPull \u0027full dynticks\u0027 support from Ingo Molnar:\n \"This tree from Frederic Weisbecker adds a new, (exciting! :-) core\n  kernel feature to the timer and scheduler subsystems: \u0027full dynticks\u0027,\n  or CONFIG_NO_HZ_FULL\u003dy.\n\n  This feature extends the nohz variable-size timer tick feature from\n  idle to busy CPUs (running at most one task) as well, potentially\n  reducing the number of timer interrupts significantly.\n\n  This feature got motivated by real-time folks and the -rt tree, but\n  the general utility and motivation of full-dynticks runs wider than\n  that:\n\n   - HPC workloads get faster: CPUs running a single task should be able\n     to utilize a maximum amount of CPU power.  A periodic timer tick at\n     HZ\u003d1000 can cause a constant overhead of up to 1.0%.  This feature\n     removes that overhead - and speeds up the system by 0.5%-1.0% on\n     typical distro configs even on modern systems.\n\n   - Real-time workload latency reduction: CPUs running critical tasks\n     should experience as little jitter as possible.  The last remaining\n     source of kernel-related jitter was the periodic timer tick.\n\n   - A single task executing on a CPU is a pretty common situation,\n     especially with an increasing number of cores/CPUs, so this feature\n     helps desktop and mobile workloads as well.\n\n  The cost of the feature is mainly related to increased timer\n  reprogramming overhead when a CPU switches its tick period, and thus\n  slightly longer to-idle and from-idle latency.\n\n  Configuration-wise a third mode of operation is added to the existing\n  two NOHZ kconfig modes:\n\n   - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named\n     as a config option.  This is the traditional Linux periodic tick\n     design: there\u0027s a HZ tick going on all the time, regardless of\n     whether a CPU is idle or not.\n\n   - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ\u003dy], this turns off the\n     periodic tick when a CPU enters idle mode.\n\n   - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the\n     tick when a CPU is idle, also slows the tick down to 1 Hz (one\n     timer interrupt per second) when only a single task is running on a\n     CPU.\n\n  The .config behavior is compatible: existing !CONFIG_NO_HZ and\n  CONFIG_NO_HZ\u003dy settings get translated to the new values, without the\n  user having to configure anything.  CONFIG_NO_HZ_FULL is turned off by\n  default.\n\n  This feature is based on a lot of infrastructure work that has been\n  steadily going upstream in the last 2-3 cycles: related RCU support\n  and non-periodic cputime support in particular is upstream already.\n\n  This tree adds the final pieces and activates the feature.  The pull\n  request is marked RFC because:\n\n   - it\u0027s marked 64-bit only at the moment - the 32-bit support patch is\n     small but did not get ready in time.\n\n   - it has a number of fresh commits that came in after the merge\n     window.  The overwhelming majority of commits are from before the\n     merge window, but still some aspects of the tree are fresh and so I\n     marked it RFC.\n\n   - it\u0027s a pretty wide-reaching feature with lots of effects - and\n     while the components have been in testing for some time, the full\n     combination is still not very widely used.  That it\u0027s default-off\n     should reduce its regression abilities and obviously there are no\n     known regressions with CONFIG_NO_HZ_FULL\u003dy enabled either.\n\n   - the feature is not completely idempotent: there is no 100%\n     equivalent replacement for a periodic scheduler/timer tick.  In\n     particular there\u0027s ongoing work to map out and reduce its effects\n     on scheduler load-balancing and statistics.  This should not impact\n     correctness though, there are no known regressions related to this\n     feature at this point.\n\n   - it\u0027s a pretty ambitious feature that with time will likely be\n     enabled by most Linux distros, and we\u0027d like you to make input on\n     its design/implementation, if you dislike some aspect we missed.\n     Without flaming us to crisp! :-)\n\n  Future plans:\n\n   - there\u0027s ongoing work to reduce 1Hz to 0Hz, to essentially shut off\n     the periodic tick altogether when there\u0027s a single busy task on a\n     CPU.  We\u0027d first like 1 Hz to be exposed more widely before we go\n     for the 0 Hz target though.\n\n   - once we reach 0 Hz we can remove the periodic tick assumption from\n     nr_running\u003e\u003d2 as well, by essentially interrupting busy tasks only\n     as frequently as the sched_latency constraints require us to do -\n     once every 4-40 msecs, depending on nr_running.\n\n  I am personally leaning towards biting the bullet and doing this in\n  v3.10, like the -rt tree this effort has been going on for too long -\n  but the final word is up to you as usual.\n\n  More technical details can be found in Documentation/timers/NO_HZ.txt\"\n\n* \u0027timers-nohz-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (39 commits)\n  sched: Keep at least 1 tick per second for active dynticks tasks\n  rcu: Fix full dynticks\u0027 dependency on wide RCU nocb mode\n  nohz: Protect smp_processor_id() in tick_nohz_task_switch()\n  nohz_full: Add documentation.\n  cputime_nsecs: use math64.h for nsec resolution conversion helpers\n  nohz: Select VIRT_CPU_ACCOUNTING_GEN from full dynticks config\n  nohz: Reduce overhead under high-freq idling patterns\n  nohz: Remove full dynticks\u0027 superfluous dependency on RCU tree\n  nohz: Fix unavailable tick_stop tracepoint in dynticks idle\n  nohz: Add basic tracing\n  nohz: Select wide RCU nocb for full dynticks\n  nohz: Disable the tick when irq resume in full dynticks CPU\n  nohz: Re-evaluate the tick for the new task after a context switch\n  nohz: Prepare to stop the tick on irq exit\n  nohz: Implement full dynticks kick\n  nohz: Re-evaluate the tick from the scheduler IPI\n  sched: New helper to prevent from stopping the tick in full dynticks\n  sched: Kick full dynticks CPU that have more than one task enqueued.\n  perf: New helper to prevent full dynticks CPUs from stopping tick\n  perf: Kick full dynticks CPU if events rotation is needed\n  ...\n"

It already implements all the idle dynticks code\nand the full dynticks depends on all that code for now.\nSo ideally the choice menu would propose CONFIG_NO_HZ_IDLE and\nCONFIG_NO_HZ_EXTENDED then both would select CONFIG_NO_HZ.\n\nOn the other hand we want to stay backward compatible: if\nCONFIG_NO_HZ is set in an older config file, we want to\nenable CONFIG_NO_HZ_IDLE by default.\n\nBut we can\u0027t afford both at the same time or we run into\na circular dependency:\n\n1) CONFIG_NO_HZ_IDLE and CONFIG_NO_HZ_EXTENDED both select\n   CONFIG_NO_HZ\n2) If CONFIG_NO_HZ is set, we default to CONFIG_NO_HZ_IDLE\n\nWe might be able to support that from Kconfig/Kbuild but it\nmay not be wise to introduce such a confusing behaviour.\n\nSo to solve this, create a new CONFIG_NO_HZ_COMMON option\nwhich gathers the common code between idle and full dynticks\n(that common code for now is simply the idle dynticks code)\nand select it from their referring Kconfig.\n\nThen we\u0027ll later create CONFIG_NO_HZ_IDLE and map CONFIG_NO_HZ\nto it for backward compatibility.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Chris Metcalf \u003ccmetcalf@tilera.com\u003e\nCc: Christoph Lameter \u003ccl@linux.com\u003e\nCc: Geoff Levand \u003cgeoff@infradead.org\u003e\nCc: Gilad Ben Yossef \u003cgilad@benyossef.com\u003e\nCc: Hakan Akkan \u003chakanakkan@gmail.com\u003e\nCc: Ingo Molnar \u003cmingo@kernel.org\u003e\nCc: Kevin Hilman \u003ckhilman@linaro.org\u003e\nCc: Li Zhong \u003czhong@linux.vnet.ibm.com\u003e\nCc: Namhyung Kim \u003cnamhyung.kim@lge.com\u003e\nCc: Paul E.
