Merge branch 'akpm' (Andrew's patch-bomb)
Merge misc VM changes from Andrew Morton: "The rest of most-of-MM. The other MM bits await a slab merge. This patch includes the addition of a huge zero_page. Not a performance boost but it an save large amounts of physical memory in some situations. Also a bunch of Fujitsu engineers are working on memory hotplug. Which, as it turns out, was badly broken. About half of their patches are included here; the remainder are 3.8 material." However, this merge disables CONFIG_MOVABLE_NODE, which was totally broken. We don't add new features with "default y", nor do we add Kconfig questions that are incomprehensible to most people without any help text. Does the feature even make sense without compaction or memory hotplug? * akpm: (54 commits) mm/bootmem.c: remove unused wrapper function reserve_bootmem_generic() mm/memory.c: remove unused code from do_wp_page() asm-generic, mm: pgtable: consolidate zero page helpers mm/hugetlb.c: fix warning on freeing hwpoisoned hugepage hwpoison, hugetlbfs: fix RSS-counter warning hwpoison, hugetlbfs: fix "bad pmd" warning in unmapping hwpoisoned hugepage mm: protect against concurrent vma expansion memcg: do not check for mm in __mem_cgroup_count_vm_event tmpfs: support SEEK_DATA and SEEK_HOLE (reprise) mm: provide more accurate estimation of pages occupied by memmap fs/buffer.c: remove redundant initialization in alloc_page_buffers() fs/buffer.c: do not inline exported function writeback: fix a typo in comment mm: introduce new field "managed_pages" to struct zone mm, oom: remove statically defined arch functions of same name mm, oom: remove redundant sleep in pagefault oom handler mm, oom: cleanup pagefault oom handler memory_hotplug: allow online/offline memory to result movable node numa: add CONFIG_MOVABLE_NODE for movable-dedicated node mm, memcg: avoid unnecessary function call when memcg is disabled ... |

Several platforms have seen pinctrl-via-devicetree conversions for simpler multiplatform. Tegra is adding data for new devices/drivers, and Exynos has a bunch of new bindings and devices added as well. So, pretty much the same progression in the right direction as the last few releases. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQySW7AAoJEIwa5zzehBx39xcP/jzEQOTOJdK4zJd1OjgrQoX/ WnhbGJT941RNjRjvDG6HmZzhpsRoE4q/zkjFEKoKELdikRW0hYoR+zPCGuB7XtN5 aF1ZQrTx4gHf4KE7doIB8slaWeOq8aG2TLFhylyy+cuaIpRK0NG0pAR0ZqWaoga9 tZFciqzplLeo50vZ+y+lVVsR40j/w29EjwPXhCV30//gGOYLyp/VDu5PRtrBdgh8 EgpcT2EWJwMCN/Upcao/q2JbQktPHPpSwnpaUAALYB20uD7k5jo7wtYE/+L9nn6B bxcCDTMVmqzNTF+y0P16hDcs5jMLVjpI0xBiyZ1G6gShpggsSZCHY5ynjAtQ19se r+2WrNfOR23k6arJuOUAQSEnLdx0T5SlW6CJeFEofKv4uoebxAbKUiNO4ShWskhd nNptX1+L3hj3zpjGcEHmL6bd+nGtyMeoG9Yekcv1oZxdVcpKhFxh0s5PEJBEeXcN M7aAWlWJkplV22Olqhpc/3INCweq6E+zBrBxZaUBW/JCzGrqBUGC0BULDPAkmC4J CKL6IqIB73jGQ4OY14IaMU20GJrIGxZ7wzXOp4aw3OUpRlxsgurfyFQeIjUvVoZL PJ8DRoAVwreVHvKfgZZVKpSAY7dwcWbxpWsYlrH3zWIC5vRJ0UFwsD0TpLJWd6Vi XA8gQcJRWKGS8E5mRY39 =Rk9v -----END PGP SIGNATURE----- Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC device tree conversions and enablement from Olof Johansson: "Continued device tree conversion and enablement across a number of platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other smaller series as well. ux500 has seen continued conversion for platforms.

mm: introduce new field "managed_pages" to struct zone
Currently a zone's present_pages is calcuated as below, which is inaccurate and may cause trouble to memory hotplug. spanned_pages - absent_pages - memmap_pages - dma_reserve. During fixing bugs caused by inaccurate zone->present_pages, we found zone->present_pages has been abused. The field zone->present_pages may have different meanings in different contexts: 1) pages existing in a zone. 2) pages managed by the buddy system. For more discussions about the issue, please refer to: http://lkml.org/lkml/2012/11/5/866 https://patchwork.kernel.org/patch/1346751/ This patchset tries to introduce a new field named "managed_pages" to struct zone, which counts "pages managed by the buddy system". And revert zone->present_pages to count "physical pages existing in a zone", which also keep in consistence with pgdat->node_present_pages. We will set an initial value for zone->managed_pages in function free_area_init_core() and will adjust it later if the initial value is inaccurate. For DMA/normal zones, the initial value is set to: (spanned_pages - absent_pages - memmap_pages - dma_reserve) Later zone->managed_pages will be adjusted to the accurate value when the bootmem allocator frees all free pages to the buddy system in function free_all_bootmem_node() and free_all_bootmem(). The bootmem allocator doesn't touch highmem pages, so highmem zones' managed_pages is set to the accurate value "spanned_pages - absent_pages" in function free_area_init_core() and won't be updated anymore. This patch also adds a new field "managed_pages" to /proc/zoneinfo and sysrq showmem.

numa: add CONFIG_MOVABLE_NODE for movable-dedicated node
We need a node which only contains movable memory. This feature is very important for node hotplug. If a node has normal/highmem, the memory may be used by the kernel and can't be offlined. If the node only contains movable memory, we can offline the memory and the node.

mm, memcg: avoid unnecessary function call when memcg is disabled
While profiling numa/core v16 with cgroup_disable=memory on the command line, I noticed mem_cgroup_count_vm_event() still showed up as high as 0.60% in perftop. This occurs because the function is called extremely often even when memcg is disabled. To fix this, inline the check for mem_cgroup_disabled() so we avoid the unnecessary function call if memcg is disabled.

mm: node_states: introduce N_MEMORY
We have N_NORMAL_MEMORY for standing for the nodes that have normal memory with zone_type <= ZONE_NORMAL. And we have N_HIGH_MEMORY for standing for the nodes that have normal or high memory. But we don't have any word to stand for the nodes that have *any* memory. And we have N_CPU but without N_MEMORY. Current code reuse the N_HIGH_MEMORY for this purpose because any node which has memory must have high memory or normal memory currently. A) But this reusing is bad for *readability*. Because the name N_HIGH_MEMORY just stands for high or normal: A.example 1) mem_cgroup_nr_lru_pages(): for_each_node_state(nid, N_HIGH_MEMORY) The user will be confused(why this function just counts for high or normal memory node? does it counts for ZONE_MOVABLE's lru pages?) until someone else tell them N_HIGH_MEMORY is reused to stand for nodes that have any memory. A.cont) If we introduce N_MEMORY, we can reduce this confusing AND make the code more clearly: A.example 2) mm/page_cgroup.c use N_HIGH_MEMORY twice: One is in page_cgroup_init(void): for_each_node_state(nid, N_HIGH_MEMORY) { It means if the node have memory, we will allocate page_cgroup map for the node. We should use N_MEMORY instead here to gaim more clearly. The second using is in alloc_page_cgroup(): if (node_state(nid, N_HIGH_MEMORY)) addr = vzalloc_node(size, nid); It means if the node has high or normal memory that can be allocated from kernel. We should keep N_HIGH_MEMORY here, and it will be better if the "any memory" semantic of N_HIGH_MEMORY is removed. B) This reusing is out-dated if we introduce MOVABLE-dedicated node. The MOVABLE-dedicated node should not appear in node_stats[N_HIGH_MEMORY] nor node_stats[N_NORMAL_MEMORY], because MOVABLE-dedicated node has no high or normal memory. In x86_64, N_HIGH_MEMORY=N_NORMAL_MEMORY, if a MOVABLE-dedicated node is in node_stats[N_HIGH_MEMORY], it is also means it is in node_stats[N_NORMAL_MEMORY], it causes SLUB wrong. The slub uses for_each_node_state(nid, N_NORMAL_MEMORY) and creates kmem_cache_node for MOVABLE-dedicated node and cause problem. In one word, we need a N_MEMORY. We just intrude it as an alias to N_HIGH_MEMORY and fix all im-proper usages of N_HIGH_MEMORY in late patches.

ARM: arm-soc: SoC updates for 3.8
This contains the bulk of new SoC development for this merge window. Two new platforms have been added, the sunxi platforms (Allwinner A1x SoCs) by Maxime Ripard, and a generic Broadcom platform for a new series of ARMv7 platforms from them, where the hope is that we can keep the platform code generic enough to have them all share one mach directory. The new Broadcom platform is contributed by Christian Daudt. Highbank has grown support for Calxeda's next generation of hardware, ECX-2000. clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also taken on maintainership of the platform. Beyond this there has been a bunch of work from a number of people on converting more platforms to IRQ domains, pinctrl conversion, cleanup and general feature enablement across most of the active platforms. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQIcBAABAgAGBQJQyLCjAAoJEIwa5zzehBx3AdQP/R+L3+EQMjiEWt/p7g/ql5Em 0SnP92CcGzrjgLTg9z1FeOazfOsGnkZAYUlDRkqfKobH3VqkhYFFtt1/0x0KMahm xcowHgMBOyimFdWT9vLK3J8U6DLui5XrEG9LGH2VL+lqmfjIyP/OOF3mVc0/+pV9 WTLAsYswdBRSeiNuF43kqlfrOwF6xsPLgiNMlc82w6BzHqoHu6dOif5M9MqWaApS V74DPmwLD371Tyit6aHqt3JOqpgiPSHlmxkzomK+5idcW3Pa7HnzzFYmx85dk/eN J2siqIkoOu7tEfjIbNZTL2MYoX4tUUKv4qZZ3IOl3YSWaV3P5ilMApF01XVrkk8E DWOMhzte9hC7L90W+/kCPLF1VyeAhCem2KQWUitO71fKur3r+3ZaUokNVvWzkJIL 7aduxAJOV2hfLgEqbjbjF3o4S8p63OV3kzivFJM1And15zDJo4+qqOh67+bPo4jj +R4du+SqzXriw4i3tDLGVpdjDffk4D41tbLzgkWAtvGyoP45yeYfHAzAh0pDFPRv ASfZVmZ5PhwAUAkIMnpC2sjgmxMYff3SYqmDgnsqXES7rbDH/hG+teymtHFTyUQp m+f60DNotSMcMvkLdvruLSB4aeTiwbfOqPn/g+aXYUlPuNMq1fVWgN7EJKWkamK4 nRwaJmLwx1/ojcVbpy2G =YMKB -----END PGP SIGNATURE----- Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC updates from Olof Johansson: "This contains the bulk of new SoC development for this merge window.

Pull cgroup changes from Tejun Heo: "A lot of activities on cgroup side. The big changes are focused on making cgroup hierarchy handling saner. - cgroup_rmdir() had peculiar semantics - it allowed cgroup destruction to be vetoed by individual controllers and tried to drain refcnt synchronously. The vetoing never worked properly and caused good deal of contortions in cgroup. memcg was the last reamining user. Michal Hocko removed the usage and cgroup_rmdir() path has been simplified significantly. This was done in a separate branch so that the memcg people can base further memcg changes on top. - The above allowed cleaning up cgroup lifecycle management and implementation of generic cgroup iterators which are used to improve hierarchy support. - cgroup_freezer updated to allow migration in and out of a frozen cgroup and handle hierarchy. If a cgroup is frozen, all descendant cgroups are frozen. - netcls_cgroup and netprio_cgroup updated to handle hierarchy properly. - Various fixes and cleanups. - Two merge commits. One to pull in memcg and rmdir cleanups (needed to build iterators). The other pulled in cgroup/for-3.7-fixes for device_cgroup fixes so that further device_cgroup patches can be stacked on top."

The problems are many-fold, from the driver not being informed about updated settings, to the driver not knowing what the intentions of the upper layers are. The first four patches tackle the serial_core layer, allowing it to provide the necessary information to drivers, and the remaining patches allow the OMAP serial driver to take advantage of this.

Pull scheduler updates from Ingo Molnar: "The biggest change affects group scheduling: we now track the runnable average on a per-task entity basis, allowing a smoother, exponential decay average based load/weight estimation instead of the previous binary on-the-runqueue/off-the-runqueue load weight method. This will inevitably disturb workloads that were in some sort of borderline balancing state or unstable equilibrium, so an eye has to be kept on regressions. For that reason the new load average is only limited to group scheduling (shares distribution) at the moment (which was also hurting the most from the prior, crude weight calculation and whose scheduling quality wins most from this change) - but we plan to extend this to regular SMP balancing as well in the future, which will simplify and speed up things a bit.

Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU update from Ingo Molnar: "The major features of this tree are: 1. A first version of no-callbacks CPUs. This version prohibits offlining CPU 0, but only when enabled via CONFIG_RCU_NOCB_CPU=y. Relaxing this constraint is in progress, but not yet ready for prime time. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/724. 2. Changes to SRCU that allows statically initialized srcu_struct structures. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/296. 3. Restructuring of RCU's debugfs output. These commits were posted to LKML at https://lkml.org/lkml/2012/10/30/341. 4. Additional CPU-hotplug/RCU improvements, posted to LKML at https://lkml.org/lkml/2012/10/30/327. Note that the commit eliminating __stop_machine() was judged to be too-high of risk, so is deferred to 3.9. 5. Changes to RCU's idle interface, most notably a new module parameter that redirects normal grace-period operations to their expedited equivalents. These were posted to LKML at https://lkml.org/lkml/2012/10/30/739. 6. Additional diagnostics for RCU's CPU stall warning facility, posted to LKML at https://lkml.org/lkml/2012/10/30/315. The most notable change reduces the default RCU CPU stall-warning time from 60 seconds to 21 seconds, so that it once again happens sooner than the softlockup timeout. 7. Documentation updates, which were posted to LKML at https://lkml.org/lkml/2012/10/30/280. A couple of late-breaking changes were posted at https://lkml.org/lkml/2012/11/16/634 and https://lkml.org/lkml/2012/11/16/547. 8.

mm, memory-hotplug: dynamic configure movable memory and portion memory
Add online_movable and online_kernel for logic memory hotplug. This is the dynamic version of "movablecore" & "kernelcore". We have the same reason to introduce it as to introduce "movablecore" & "kernelcore". It has the same motive as "movablecore" & "kernelcore", but it is dynamic/running-time: o We can configure memory as kernelcore or movablecore after boot. Userspace workload is increased, we need more hugepage, we can't use "online_movable" to add memory and allow the system use more THP(transparent-huge-page), vice-verse when kernel workload is increase. Also help for virtualization to dynamic configure host/guest's memory, to save/(reduce waste) memory. Memory capacity on Demand o When a new node is physically online after boot, we need to use "online_movable" or "online_kernel" to configure/portion it as we expected when we logic-online it. This configuration also helps for physically-memory-migrate. o all benefit as the same as existed "movablecore" & "kernelcore". o Preparing for movable-node, which is very important for power-saving, hardware partitioning and high-available-system(hardware fault management). (Note, we don't introduce movable-node here.) Action behavior: When a memoryblock/memorysection is onlined by "online_movable", the kernel will not have directly reference to the page of the memoryblock, thus we can remove that memory any time when needed. When it is online by "online_kernel", the kernel can use it. When it is online by "online", the zone type doesn't changed. Current constraints: Only the memoryblock which is adjacent to the ZONE_MOVABLE can be online from ZONE_NORMAL to ZONE_MOVABLE.

bootmem: fix wrong call parameter for free_bootmem()
It is strange that alloc_bootmem() returns a virtual address and free_bootmem() requires a physical address. Anyway, free_bootmem()'s first parameter should be physical address.

mm, oom: fix race when specifying a thread as the oom origin
test_set_oom_score_adj() and compare_swap_oom_score_adj() are used to specify that current should be killed first if an oom condition occurs in between the two calls. The usage is short oom_score_adj = test_set_oom_score_adj(OOM_SCORE_ADJ_MAX); ... compare_swap_oom_score_adj(OOM_SCORE_ADJ_MAX, oom_score_adj); to store the thread's oom_score_adj, temporarily change it to the maximum score possible, and then restore the old value if it is still the same. This happens to still be racy, however, if the user writes OOM_SCORE_ADJ_MAX to /proc/pid/oom_score_adj in between the two calls. The compare_swap_oom_score_adj() will then incorrectly reset the old value prior to the write of OOM_SCORE_ADJ_MAX. To fix this, introduce a new oom_flags_t member in struct signal_struct that will be used for per-thread oom killer flags. KSM and swapoff can now use a bit in this member to specify that threads should be killed first in oom conditions without playing around with oom_score_adj. This also allows the correct oom_score_adj to always be shown when reading /proc/pid/oom_score.

mm, oom: change type of oom_score_adj to short
The maximum oom_score_adj is 1000 and the minimum oom_score_adj is -1000, so this range can be represented by the signed short type with no functional change. The extra space this frees up in struct signal_struct will be used for per-thread oom kill flags in the next patch.

mm: introduce putback_movable_pages()
The PATCH "mm: introduce compaction and migration for virtio ballooned pages" hacks around putback_lru_pages() in order to allow ballooned pages to be re-inserted on balloon page list as if a ballooned page was like a LRU page. As ballooned pages are not legitimate LRU pages, this patch introduces putback_movable_pages() to properly cope with cases where the isolated pageset contains ballooned pages and LRU pages, thus fixing the mentioned inelegant hack around putback_lru_pages().
