include/linux/file.h: remove get_unused_fd() macro
Macro get_unused_fd() is used to allocate a file descriptor with default flags. Those default flags (0) don't enable close-on-exec. This can be seen as an unsafe default: in most case close-on-exec should be enabled to not leak file descriptor across exec(). It would be better to have a "safer" default set of flags, eg. O_CLOEXEC must be used to enable close-on-exec. Instead this patch removes get_unused_fd() so that out of tree modules won't be affect by a runtime behavor change which might introduce other kind of bugs: it's better to catch the change at build time, making it easier to fix. Removing the macro will also promote use of get_unused_fd_flags() (or anon_inode_getfd()) with flags provided by userspace. Or, if flags cannot be given by userspace, with flags set to O_CLOEXEC by default.

exit: ptrace: shift "reap dead" code from exit_ptrace() to forget_original_parent()
Now that forget_original_parent() uses ->ptrace_entry for EXIT_DEAD tasks, we can simply pass "dead_children" list to exit_ptrace() and remove another release_task() loop. Plus this way we do not need to drop and reacquire tasklist_lock. Also shift the list_empty(ptraced) check, if we want this optimization it makes sense to eliminate the function call altogether.

mm: embed the memcg pointer directly into struct page
Memory cgroups used to have 5 per-page pointers. To allow users to disable that amount of overhead during runtime, those pointers were allocated in a separate array, with a translation layer between them and struct page. There is now only one page pointer remaining: the memcg pointer, that indicates which cgroup the page is associated with when charged. The complexity of runtime allocation and the runtime translation overhead is no longer justified to save that *potential* 0.19% of memory. With CONFIG_SLUB, page->mem_cgroup actually sits in the doubleword padding after the page->private member and doesn't even increase struct page, and then this patch actually saves space. Remaining users that care can still compile their kernels without CONFIG_MEMCG. text data bss dec hex filename 8828345 1725264 983040 11536649 b00909 vmlinux.old 8827425 1725264 966656 11519345 afc571 vmlinux.new [mhocko@suse.cz: update Documentation/cgroups/memory.txt] Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Michal Hocko <mhocko@suse.cz> Acked-by: Vladimir Davydov <vdavydov@parallels.com> Acked-by: David S.

memcg: use generic slab iterators for showing slabinfo
Let's use generic slab_start/next/stop for showing memcg caches info. In contrast to the current implementation, this will work even if all memcg caches' info doesn't fit into a seq buffer (a page), plus it simply looks neater. Actually, the main reason I do this isn't mere cleanup. I'm going to zap the memcg_slab_caches list, because I find it useless provided we have the slab_caches list, and this patch is a step in this direction. It should be noted that before this patch an attempt to read memory.kmem.slabinfo of a cgroup that doesn't have kmem limit set resulted in -EIO, while after this patch it will silently show nothing except the header, but I don't think it will frustrate anyone.

mm, compaction: pass classzone_idx and alloc_flags to watermark checking
Compaction relies on zone watermark checks for decisions such as if it's worth to start compacting in compaction_suitable() or whether compaction should stop in compact_finished(). The watermark checks take classzone_idx and alloc_flags parameters, which are related to the memory allocation request. But from the context of compaction they are currently passed as 0, including the direct compaction which is invoked to satisfy the allocation request, and could therefore know the proper values. The lack of proper values can lead to mismatch between decisions taken during compaction and decisions related to the allocation request. Lack of proper classzone_idx value means that lowmem_reserve is not taken into account. This has manifested (during recent changes to deferred compaction) when DMA zone was used as fallback for preferred Normal zone. compaction_suitable() without proper classzone_idx would think that the watermarks are already satisfied, but watermark check in get_page_from_freelist() would fail. Because of this problem, deferring compaction has extra complexity that can be removed in the following patch. The issue (not confirmed in practice) with missing alloc_flags is opposite in nature. For allocations that include ALLOC_HIGH, ALLOC_HIGHER or ALLOC_CMA in alloc_flags (the last includes all MOVABLE allocations on CMA-enabled systems) the watermark checking in compaction with 0 passed will be stricter than in get_page_from_freelist(). In these cases compaction might be running for a longer time than is really needed. Another issue compaction_suitable() is that the check for "does the zone need compaction at all?" comes only after the check "does the zone have enough free free pages to succeed compaction". The latter considers extra pages for migration and can therefore in some situations fail and return COMPACT_SKIPPED, although the high-order allocation would succeed and we should return COMPACT_PARTIAL. This patch fixes these problems by adding alloc_flags and classzone_idx to struct compact_control and related functions involved in direct compaction and watermark checking. Where possible, all other callers of compaction_suitable() pass proper values where those are known. This is currently limited to classzone_idx, which is sometimes known in kswapd context. However, the direct reclaim callers should_continue_reclaim() and compaction_ready() do not currently know the proper values, so the coordination between reclaim and compaction may still not be as accurate as it could. This can be fixed later, if it's shown to be an issue. Additionaly the checks in compact_suitable() are reordered to address the second issue described above. The effect of this patch should be slightly better high-order allocation success rates and/or less compaction overhead, depending on the type of allocations and presence of CMA. It allows simplifying deferred compaction code in a followup patch. When testing with stress-highalloc, there was some slight improvement (which might be just due to variance) in success rates of non-THP-like allocations.

mm: introduce single zone pcplists drain
The functions for draining per-cpu pages back to buddy allocators currently always operate on all zones. There are however several cases where the drain is only needed in the context of a single zone, and spilling other pcplists is a waste of time both due to the extra spilling and later refilling. This patch introduces new zone pointer parameter to drain_all_pages() and changes the dummy parameter of drain_local_pages() to be also a zone pointer. When NULL is passed, the functions operate on all zones as usual. Passing a specific zone pointer reduces the work to the single zone. All callers are updated to pass the NULL pointer in this patch. Conversion to single zone (where appropriate) is done in further patches.

mm: memcontrol: lockless page counters
Memory is internally accounted in bytes, using spinlock-protected 64-bit counters, even though the smallest accounting delta is a page. The counter interface is also convoluted and does too many things. Introduce a new lockless word-sized page counter API, then change all memory accounting over to it. The translation from and to bytes then only happens when interfacing with userspace. The removed locking overhead is noticable when scaling beyond the per-cpu charge caches - on a 4-socket machine with 144-threads, the following test shows the performance differences of 288 memcgs concurrently running a page fault benchmark: vanilla: 18631648.500498 task-clock (msec) # 140.643 CPUs utilized ( +- 0.33% ) 1,380,638 context-switches # 0.074 K/sec ( +- 0.75% ) 24,390 cpu-migrations # 0.001 K/sec ( +- 8.44% ) 1,843,305,768 page-faults # 0.099 M/sec ( +- 0.00% ) 50,134,994,088,218 cycles # 2.691 GHz ( +- 0.33% ) <not supported> stalled-cycles-frontend <not supported> stalled-cycles-backend 8,049,712,224,651 instructions # 0.16 insns per cycle ( +- 0.04% ) 1,586,970,584,979 branches # 85.176 M/sec ( +- 0.05% ) 1,724,989,949 branch-misses # 0.11% of all branches ( +- 0.48% ) 132.474343877 seconds time elapsed ( +- 0.21% ) lockless: 12195979.037525 task-clock (msec) # 133.480 CPUs utilized ( +- 0.18% ) 832,850 context-switches # 0.068 K/sec ( +- 0.54% ) 15,624 cpu-migrations # 0.001 K/sec ( +- 10.17% ) 1,843,304,774 page-faults # 0.151 M/sec ( +- 0.00% ) 32,811,216,801,141 cycles # 2.690 GHz ( +- 0.18% ) <not supported> stalled-cycles-frontend <not supported> stalled-cycles-backend 9,999,265,091,727 instructions # 0.30 insns per cycle ( +- 0.10% ) 2,076,759,325,203 branches # 170.282 M/sec ( +- 0.12% ) 1,656,917,214 branch-misses # 0.08% of all branches ( +- 0.55% ) 91.369330729 seconds time elapsed ( +- 0.45% ) On top of improved scalability, this also gets rid of the icky long long types in the very heart of memcg, which is great for 32 bit and also makes the code a lot more readable. Notable differences between the old and new API: - res_counter_charge() and res_counter_charge_nofail() become page_counter_try_charge() and page_counter_charge() resp. to match the more common kernel naming scheme of try_do()/do() - res_counter_uncharge_until() is only ever used to cancel a local counter and never to uncharge bigger segments of a hierarchy, so it's replaced by the simpler page_counter_cancel() - res_counter_set_limit() is replaced by page_counter_limit(), which expects its callers to serialize against themselves - res_counter_memparse_write_strategy() is replaced by page_counter_limit(), which rounds down to the nearest page size - rather than up. This is more reasonable for explicitely requested hard upper limits. - to keep charging light-weight, page_counter_try_charge() charges speculatively, only to roll back if the result exceeds the limit. Because of this, a failing bigger charge can temporarily lock out smaller charges that would otherwise succeed. The error is bounded to the difference between the smallest and the biggest possible charge size, so for memcg, this means that a failing THP charge can send base page charges into reclaim upto 2MB (4MB) before the limit would have been reached. This should be acceptable.

Merge branch 'irq-irqdomain-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq domain updates from Thomas Gleixner: "The real interesting irq updates: - Support for hierarchical irq domains: For complex interrupt routing scenarios where more than one interrupt related chip is involved we had no proper representation in the generic interrupt infrastructure so far. That made people implement rather ugly constructs in their nested irq chip implementations. The main offenders are x86 and arm/gic. To distangle that mess we have now hierarchical irqdomains which seperate the various interrupt chips and connect them via the hierarchical domains. That keeps the domain specific details internal to the particular hierarchy level and removes the criss/cross referencing of chip internals. The resulting hierarchy for a complex x86 system will look like this: vector mapped: 74 msi-0 mapped: 2 dmar-ir-1 mapped: 69 ioapic-1 mapped: 4 ioapic-0 mapped: 20 pci-msi-2 mapped: 45 dmar-ir-0 mapped: 3 ioapic-2 mapped: 1 pci-msi-1 mapped: 2 htirq mapped: 0 Neither ioapic nor pci-msi know about the dmar interrupt remapping between themself and the vector domain. If interrupt remapping is disabled ioapic and pci-msi become direct childs of the vector domain.

Pull scheduler updates from Ingo Molnar: "The main changes in this cycle are: - 'Nested Sleep Debugging', activated when CONFIG_DEBUG_ATOMIC_SLEEP=y. This instruments might_sleep() checks to catch places that nest blocking primitives - such as mutex usage in a wait loop. Such bugs can result in hard to debug races/hangs. Another category of invalid nesting that this facility will detect is the calling of blocking functions from within schedule() -> sched_submit_work() -> blk_schedule_flush_plug(). There's some potential for false positives (if secondary blocking primitives themselves are not ready yet for this facility), but the kernel will warn once about such bugs per bootup, so the warning isn't much of a nuisance. This feature comes with a number of fixes, for problems uncovered with it, so no messages are expected normally. - Another round of sched/numa optimizations and refinements, for CONFIG_NUMA_BALANCING=y. - Another round of sched/dl fixes and refinements.

asm-generic: asm/io.h rewrite
While there normally is no reason to have a pull request for asm-generic but have all changes get merged through whichever tree needs them, I do have a series for 3.19. There are two sets of patches that change significant portions of asm/io.h, and this branch contains both in order to resolve the conflicts: - Will Deacon has done a set of patches to ensure that all architectures define {read,write}{b,w,l,q}_relaxed() functions or get them by including asm-generic/io.h. These functions are commonly used on ARM specific drivers to avoid expensive L2 cache synchronization implied by the normal {read,write}{b,w,l,q}, but we need to define them on all architectures in order to share the drivers across architectures and to enable CONFIG_COMPILE_TEST configurations for them - Thierry Reding has done an unrelated set of patches that extends the asm-generic/io.h file to the degree necessary to make it useful on ARM64 and potentially other architectures. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVIdwNmCrR//JCVInAQJWuw/9FHt2ThMnI1J1Jqy4CVwtyjWTSa6Y/uVj xSytS7AOvmU/nw1quSoba5mN9fcUQUtK9kqjqNcq71WsQcDE6BF9SFpi9cWtjWcI ZfWsC+5kqry/mbnuHefENipem9RqBrLbOBJ3LARf5M8rZJuTz1KbdZs9r9+1QsCX ou8jeqVvNKUn9J1WyekJBFSrPOtZ4bCUpeyh23JHRfPtJeAHNOuPuymj6WceAz98 uMV1icRaCBMySsf9HgsHRYW5HwuCm3MrrYj6ukyPpgxYz7FRq4hJLDs6GnlFtAGb 71g87NpFdB32qbW+y1ntfYaJyUryMHMVHBWcV5H9m0btdHTRHYZjoOGOPuyLHHO8 +l4/FaOQhnDL8cNDj0HKfhdlyaFylcWgs1wzj68nv31c1dGjcJcQiyCDwry9mJhr erh4EewcerUvWzbBMQ4JP1f8syKMsKwbo1bVU61a1RQJxEqVCzJMLweGSOFmqMX2 6E4ZJVWv81UFLoFTzYx+7+M45K4NWywKNQdzwKmqKHc4OQyvq4ALJI0A7SGFJdDR HJ7VqDiLaSdBitgJcJUxNzKcyXij6wE9jE1fBe3YDFE4LrnZXFVLN+MX6hs7AIFJ vJM1UpxRxQUMGIH2m7rbDNazOAsvQGxINOjNor23cNLuf6qLY1LrpHVPQDAfJVvA 6tROM77bwIQ= =xUv6 -----END PGP SIGNATURE----- Merge tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic asm/io.h rewrite from Arnd Bergmann: "While there normally is no reason to have a pull request for asm-generic but have all changes get merged through whichever tree needs them, I do have a series for 3.19.

ARM: SoC/OMAP GPMC driver cleanup and move for 3.19
The GPMC driver has traditionally been considered a part of the OMAP platform code and tightly interweaved with some of the boards. With this cleanup, it has finally come to the point where it makes sense to move it out of arch/arm into drivers/memory, where we already have other drivers for similar hardware. The cleanups are still ongoing, with the goal of eventually having a standalone driver that does not require an interface to architecture code. This is a separate branch because of dependencies on multiple other branches, and to keep the drivers changes separate from the normal cleanups. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVIcj7mCrR//JCVInAQIEtBAAoxn09fc4oeyBy9HeAgcQSxglqlyiJzTG YeIYN3Hz9kCRh/KDG35OQDD0Zv6Yw3m4QLYym5x/W2atMl+7AwBOUKGAi6neEHzv DbhvmAr8/2I+3RnUQDAxcbqY/p3/sSatWsPgwrgXWmGJHQm5Ur/IfUcnOmqfA6w4 xag8EdwX43zxUCF7MFTdD5Vo4uzoYNtPaPHpEtFBn/UkGMolktUCXZPBD1DvgQEP Mdy9yKhpYy/6N/k8ZQUCfD177GW5mJMNDrQN3e+vdqJ05NBBfiORhJCxilo74FVQ NpX7I4AoYqgc+c0xJpQSZF2bAfAt53Ac8bPG6fNAf1GCw7O8ryjNybHWw9hK1mr3 aS4EEVsC3UJh/d6NAhbPWfB4reL9WqUgGapN8AiVsurt1Rj+eAp6mCY3qM37kPs4 feGBbCL0lfEPVKTWHskcdUjxxcSsj1xTPM/VDvitITjgINfv6EqUHDLPRT9V7ta1 VVbFwIgshScam2T5AolMd1CB8mkaTkkbZFnMqz93lFs43vltJFFqJOCnfPKsYgMz gf4sJ8/029sUJV2yjEHHMQNyurpGPqJ+BHa6bCLX82ERePFNJvBnm8Zm+kizNbD2 CGN38tysXOxKL6jIqT9D0bKO40w1dLJjamsl1SfesDBijZChhF77Lnpwx/EKtj+/ jYSRIijpCWk= =U4Fz -----END PGP SIGNATURE----- Merge tag 'omap-gpmc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC/OMAP GPMC driver cleanup and move from Arnd Bergmann: "The GPMC driver has traditionally been considered a part of the OMAP platform code and tightly interweaved with some of the boards.

The DT branch adds a lot of new stuff for additional SoC and board support. The branch is the largest one and contains 513 out of the total 972 non-merge arm-soc changesets for 3.19. Most of the changes are about enabling additional on-chip devices for existing machines, but there are also an unusual number of new SoC types being added this time: * AMLogic Meson8 * ARM Realview in DT mode * Allwinner A80 * Broadcom BCM47081 * Broadcom Cygnus * Freescale LS1021A * Freescale Vybrid 500 series * Mediatek MT6592, MT8127, MT8135 * STMicroelectronics STiH410 * Samsung Exynos4415 The level of support for the above differs widely, some are just stubs with nothing more than CPU, memory and a UART, but others are fairly complete. As usual, these get extended over time. There are also many new boards getting added, this is the list of model strings that are showing up in new dts files: * ARM RealView PB1176 * Altera SOCFPGA Arria 10 * Asus RT-N18U (BCM47081) * Buffalo WZR-1750DHP (BCM4708) * Buffalo WZR-600DHP2 (BCM47081) * Cygnus Enterprise Phone (BCM911360_ENTPHN) * D-Link DIR-665 * Google Spring * IGEP COM MODULE Rev.

ARM: SoC driver updates for 3.19
These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree. The largest single change here this time around is the Tegra iommu/memory controller driver, which gets updated to the new iommu DT binding. More drivers like this are likely to follow for the following merge window, but we should be able to do those through the iommu maintainer. Other notable changes are: * reset controller drivers from the reset maintainer (socfpga, sti, berlin) * fixes for the keystone navigator driver merged last time * at91 rtc driver changes related to the at91 cleanups * ARM perf driver changes from Will Deacon * updates for the brcmstb_gisb driver -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVIcj4mCrR//JCVInAQIvWg//WD72+2q0RmEvu8r/YN4SDfg5iY7OMzgy Jyt6rN1IhXBY5GJL5Hil1q2JP/7o8vypekllohmBYWzXO3ZJ2VK6NPIXEMuzaiCz D9gmb+N6FdR2L2iYPv7B/3uOf55pHjBu525+vLspCTOgcWBrLgCnA9e9Yg462AEf VP3x+kV0AH25lovEi3mPrc2e46jnl0Mzp3f3PCkPqRSEMn7sxu9ipii+elxvArYp jYYCB03ZEBFa7T0e4HD38gnVLbC6dTj47AcSCWYP9WhxJ2RmCQKRBEnJre02hgar NPg8z+OrUACIAkvJHzg3WccmXdi0aqQ2JDsl46Tkl7pA6NdyMLfizT3OiZnMRmgc 34H0ZSxclW+j25aI8OmDpv2ypZev+UAzkbRobcvF+aV/zJeAX88tPgcshfCUVZll ZIqO7oJB73nCl1XBLv2ZrLV2tcOox6jL/5LQt0WYA5Szg5upo7D1fZl8v5jXX7eJ C62ychuABs6hsmH5jEy+73kdpHbYft7dZfGZxdgq1AIOkdWoynCze/R7Vj24xoXR 118cTNN9ZTPHmN5yxUvuGoqA3FWOqkJXaTS4W0hRD6OxOGTsTV4FIlRnD+K7feOW ng1yfIcvKR1Dx7tsySTHQK+bZGNnovA/ENPK6VDuhbwE62Lx7N5hcbsSIKKwRI9C D1m1fC+AIcQ= =MwMG -----END PGP SIGNATURE----- Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Arnd Bergmann: "These are changes for drivers that are intimately tied to some SoC and for some reason could not get merged through the respective subsystem maintainer tree.

ARM: SoC cleanups for 3.19
The remaining cleanups for 3.19 are to a large part result of devicetree conversion nearing completion on two other platforms besides AT91: * Like AT91, Renesas shmobile is in the process to migrate to DT and multiplatform, but using a different approach of doing it one SoC at a time. For 3.19, the r8a7791 platform and associated\ "Koelsch" board are considered complete and we remove the non-DT non-multiplatform support for this. * The ARM Versatile Express has supported DT and multiplatform for a long time, but we have still kept the legacy board files around, because not all drivers were fully working before. We have finally taken the last step to remove the board files. Other changes in this branch are preparation for the later branches or just unrelated to the more interesting changes: * The dts files for arm64 get moved into per-vendor directories for a clearer structure. * Some dead code removal (zynq, exynos, davinci, imx) * Using pr_*() macros more consistently instead of printk(KERN_*) in some platform code. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIVAwUAVIdpgGCrR//JCVInAQIr/BAA3UZvPPf5dwy5OkULPTghvWueeL9NWZHr 8KwNWIIkIzCgr8zUf2HrMRRLtG429WQWHWxNA+TH9HpcHFGo/zJDBPaJ63cb3Rv1 YLDGJ0zYPXjOsiWUWHm2M5B4hWj0Is5CwYnuozcpLykzQ9QsLMTIv2CAXoJXpH9S sAdx/B5e9G7IqzlJRgbvCPNAZleLYUneYoIW5L68MaFIjfKXVrHzY6w0CJFt/UDa CVbP0iwVQNnL1Opr3ABAkBkJ7rrFU17jpBWMtrNsyyMCZQADiV5Z4+IBnW0uWSZj zn92dycwOSYRmrgOrI2J6r5vFtxWRyWfR5Au5rD02oQTIucGiLmaKMV5gNhoQrEq v53IknDZzqv+xbiARGnJKGdJs70AYjrurpNgXXzJt3W4dZ6vssotxhiYEXbpPPDN v5QxrOStePY+qBHeMLuQi8VoV9SI+j/YAiaXak4QWmiGHVDzvBfZ2P3wMCbj04Jp oxCZ6IGMczYwvqQ8vWXJOueLm+IfM0GcEFwslUwO95rMRMv7JRCXdvfNhL7wLlu8 f2Hd/Pk/u0bOUQXhZlFKNRFg78t4hgD1hMKHgmpEDTZ8P1XMuIrWoQu0xkSQZsYG MiGIqwRd5Ow9OWzWq3DNJ4EjhmvPYv2X/Dcvu7Jv4yq1zZQ8G6OnWkmWWn5ghq6M grvB27RnbuE= =Apdh -----END PGP SIGNATURE----- Merge tag 'cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanups from Arnd Bergmann: "The remaining cleanups for 3.19 are to a large part result of devicetree conversion nearing completion on two other platforms besides AT91: - Like AT91, Renesas shmobile is in the process to migrate to DT and multiplatform, but using a different approach of doing it one SoC at a time.

ARM: SoC cleanup on mach-at91 for 3.19
On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer. All remaining board files that were written in C are dropped, and the ancient at91x40 sub-platform (based on an MMU-less ARM7) is removed altogether. Cleaning up the last pieces was great fun, so I took the time to do some of the coding myself and removed several hundred code lines that ended up unused after the board files were done. There are still a couple of AT91 specific device drivers that are not converted to DT (CF, USB-OTG) and currently not working, and the platform itself is not "multiplatform"-enabled, but both issues are going to be taken care of in the 3.20 cycle. This is split out from the other cleanups purely based on the size of the branch. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iD8DBQBUhyNX5t5GS2LDRf4RAnjxAKCER7eoLNadu1/93n/a9d1nUz4MoQCcCZUq BolxCOi0wr4YTcQtp7rHzWI= =ykAB -----END PGP SIGNATURE----- Merge tag 'at91-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC cleanup on mach-at91 from Arnd Bergmann: "On Atmel AT91, the conversion to device tree is now considered complete, and all machines that were not already converted in 3.18 are assumed to be unused and dropped by the maintainer.

SCSI for-linus on 20141208
This patch is the usual mix of driver updates (srp, ipr, scsi_debug, NCR5380, fnic, 53c974, ses, wd719x, hpsa, megaraid_sas). Of those, wd7a9x is new and 53c974 is a rewrite of the old tmscsim driver and the extensive work by Finn Thain rewrites all the NCR5380 based drivers. There's also extensive infrastructure updates: a new logging infrastructure for sense information and a rewrite of the tagged command queue API and an assortment of minor updates.

- Significant DM thin-provisioning performance improvements to meet
performance requirements that were requested by the Gluster distributed filesystem. Specifically, dm-thinp now takes care to aggregate IO that will be issued to the same thinp block before issuing IO to the underlying devices. This really helps improve performance on HW RAID6 devices that have a writeback cache because it avoids RMW in the HW RAID controller. - Some stable fixes: fix leak in DM bufio if integrity profiles were enabled, use memzero_explicit in DM crypt to avoid any potential for information leak, and a DM cache fix to properly mark a cache block dirty if it was promoted to the cache via the overwrite optimization. - A few simple DM persistent data library fixes - DM cache multiqueue policy block promotion improvements. - DM cache discard improvements that take advantage of range (multiblock) discard support in the DM bio-prison. This allows for much more efficient bulk discard processing (e.g. when mkfs.xfs discards the entire device). - Some small optimizations in DM core and RCU deference cleanups - DM core changes to suspend/resume code to introduce the new internal suspend/resume interface that the DM thin-pool target now uses to suspend/resume active thin devices when the thin-pool must suspend/resume. This avoids forcing userspace to track all active thin volumes in a thin-pool when the thin-pool is suspended for the purposes of metadata or data space resize. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJUhcvVAAoJEMUj8QotnQNaB78H+wSA6sDJGOhc6e1KlWoFh4Hx hTmwm/O8Fxrp9StO3NPlcv9l+l9FX9pGzN/lo3OsxgWMTs/vLTKZ5SAe3/YT3/b9 6SFC7pC70+glakgMhhXWRvoeSEQC1OWb5BuvOF8irl2n+7B9NAn/zHd9pgpmyWHp nBXK2GJBMzVSiI47NMjo2n6007LgQq0xxSJ9luwdrpwjDqD1d406DrhzbHou5H2Y b8XJGQzUy0GZCX8ycwPVXo9svp2Bc+XajVcgOj5Qg7s2uV5car8NN7TxhSOKSXn2 VpiSyEa2MLHAbFuWtGs8XO98z/m5JlGf1eIgRO4s7w59URgpzdxOHXLlAoyqIGw= =opXi -----END PGP SIGNATURE----- Merge tag 'dm-3.19-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Significant DM thin-provisioning performance improvements to meet performance requirements that were requested by the Gluster distributed filesystem.
