Pull part one of ARM SoC updates from Olof Johansson: "A quite large set of SoC updates this cycle. In no particular order: - Multi-cluster power management for Samsung Exynos, adding support for big.LITTLE CPU switching on EXYNOS5 - SMP support for Marvell Armada 375 and 38x - SMP rework on Allwinner A31 - Xilinx Zynq support for SOC_BUS, big endian - Marvell orion5x platform cleanup, modernizing the implementation and moving to DT. - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so that their platform can be enabled in the same kernel binary as most of the other v7 platforms in the tree. \o/ The work isn't quite complete, there's some driver fixes still needed, but the basics now work. New SoC support added: - Freescale i.MX6SX - LSI Axxia AXM55xx SoCs - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800 - STi STIH407 plus a large set of various smaller updates for different platforms.

Pull block core updates from Jens Axboe: "It's a big(ish) round this time, lots of development effort has gone into blk-mq in the last 3 months. Generally we're heading to where 3.16 will be a feature complete and performant blk-mq. scsi-mq is progressing nicely and will hopefully be in 3.17. A nvme port is in progress, and the Micron pci-e flash driver, mtip32xx, is converted and will be sent in with the driver pull request for 3.16. This pull request contains: - Lots of prep and support patches for scsi-mq have been integrated. All from Christoph. - API and code cleanups for blk-mq from Christoph. - Lots of good corner case and error handling cleanup fixes for blk-mq from Ming Lei. - A flew of blk-mq updates from me: * Provide strict mappings so that the driver can rely on the CPU to queue mapping. This enables optimizations in the driver. * Provided a bitmap tagging instead of percpu_ida, which never really worked well for blk-mq. percpu_ida relies on the fact that we have a lot more tags available than we really need, it fails miserably for cases where we exhaust (or are close to exhausting) the tag space. * Provide sane support for shared tag maps, as utilized by scsi-mq * Various fixes for IO timeouts. * API cleanups, and lots of perf tweaks and optimizations. - Remove 'buffer' from struct request. This is ancient code, from when requests were always virtually mapped. Kill it, to reclaim some space in struct request. From me. - Remove 'magic' from blk_plug. Since we store these on the stack and since we've never caught any actual bugs with this, lets just get rid of it. From me. - Only call part_in_flight() once for IO completion, as includes two atomic reads. Hopefully we'll get a better implementation soon, as the part IO stats are now one of the more expensive parts of doing IO on blk-mq. From me. - File migration of block code from {mm,fs}/ to block/. This includes bio.c, bio-integrity.c, bounce.c, and ioprio.c. From me, from a discussion on lkml. That should describe the meat of the pull request.

Merge tag 'gpio-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio into next Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v3.16 series. There is a lot of action in the GPIO subsystem doing refactorings and cleanups, almost as many deletions as insertions and minor feature growth and no new drivers this time. Which is actually pretty nice. Some GPIO-related stuff will come in through the pin control tree as well. Details: - We are finalizing and fixing up the gpiochip irqchip helpers bringing a helpful irqchip implementation into the gpiolib core and avoiding duplicate code and, more importantly, duplicate bug fixes: * Support for using the helpers with threaded interrupt handlers as used on sleeping GPIO-irqchips * Do not set up hardware triggers for edges or levels if the default IRQ type is IRQ_TYPE_NONE - some drivers would exploit the fact that you could get default initialization of the IRQ type from the core at probe() but if no default type is set up from the helper, we should not call the driver to configure anything. Wait until a consumer requests the interrupt instead. * Make the irqchip helpers put the GPIO irqs into their own lock class. The GPIO irqchips can often emit (harmless, but annoying) lockdep warnings about recursions when they are in fact just cascaded IRQs. By putting them into their own lock class we help the lockdep core to keep track of things. * Switch the tc3589x GPIO expanders to use the irqchip helpers * Switch the OMAP GPIO driver to use the irqchip helpers * Add some documentation for the irqchip helpers * select IRQ_DOMAIN when using the helpers since some platforms may not be using this by default and it's a strict dependency. - Continued GPIO descriptor refactoring: * Remove the one instance of gpio_to_desc() from the device tree code, making the OF GPIO code use GPIO descriptors only. * Introduce gpiod_get_optional() and gpiod_get_optional_index() akin to the similar regulator functions for cases where the use of GPIO is optional and not strictly required. * Make of_get_named_gpiod_flags() private - we do not want to unnecessarily expose APIs to drivers that make the gpiolib harder than necessary to maintain and refactor. Privatize this function. - Support "-gpio" suffix for the OF GPIO retrieveal path. We used to look for "foo-gpios" or just "gpios" in device tree nodes, but it turns out that some drivers with a single GPIO line will just state "foo-gpio" (singularis). Sigh. Support this with a fallback looking for it, as this simplifies driver code and handles it in core code. - Switch the ACPI GPIO core to fetch GPIOs with the *_cansleep function variants as the GPIO operation region handler can sleep, and shall be able to handle gpiochips that sleep. - Tons of cleanups and janitorial work from Jingoo Han, Axel Lin, Javier Martinez Canillas and Abdoulaye Berthe. Notably Jingoo cut off a ton of pointless OOM messages. - Incremental development and fixes for various drivers, nothing really special here" * tag 'gpio-v3.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (85 commits) gpio: select IRQ_DOMAIN for gpiolib irqchip helpers gpio: pca953x: use gpiolib irqchip helpers gpio: pcf857x: Add IRQF_SHARED when request irq gpio: pcf857x: Avoid calling irq_domain_cleanup twice gpio: mcp23s08: switch chip count to int gpio: dwapb: use a second irq chip gpio: ep93xx: Use devm_ioremap_resource() gpio: mcp23s08: fixed count variable for devicetree probing gpio: Add run-time dependencies to R-Car driver gpio: pch: add slab include Documentation / ACPI: Fix location of GPIO documentation gpio / ACPI: use *_cansleep version of gpiod_get/set APIs gpio: generic: add request function pointer gpio-pch: Fix Kconfig dependencies gpio: make of_get_named_gpiod_flags() private gpio: gpioep93xx: use devm functions gpio: janzttl: use devm function gpio: timberdale: use devm functions gpio: bt8xx: use devm function for memory allocation gpio: include linux/bug.h in interface header ...

lock_parent() very much on purpose does nested locking of dentries, and is careful to maintain the right order (lock parent first). But because it didn't annotate the nested locking order, lockdep thought it might be a deadlock on d_lock, and complained. Add the proper annotation for the inner locking of the child dentry to make lockdep happy. Introduced by commit 046b961b ("shrink_dentry_list(): take parent's ->d_lock earlier").

We have callers outside of the blk-mq proper (like timeouts) that want to call __blk_mq_complete_request(), so rename the function and put the decision code for whether to use ->softirq_done_fn or blk_mq_endio() into __blk_mq_complete_request(). This also makes the interface more logical again. blk_mq_complete_request() attempts to atomically mark the request completed, and calls __blk_mq_complete_request() if successful. __blk_mq_complete_request() then just ends the request.

So a few people complained that commit 177cf92d Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Apr 1 22:14:59 2014 +0200 drm/crtc-helpers: fix dpms on logic which was merged into 3.15-rc1, broke resume on radeons. Strangely git bisect lead everyone to commit 25f397a4 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 19 18:57:11 2013 +0200 drm/crtc-helper: explicit DPMS on after modeset which was merged long ago and actually part of 3.14. Digging deeper I've noticed (again) that the call to drm_helper_resume_force_mode in the radeon resume handlers was a no-op previously because everything gets shut down on suspend. radeon does this with explicit calls to drm_helper_connector_dpms with DPMS_OFF. But with 177c we now force the dpms state to ON, so suddenly resume_force_mode actually forced the crtcs back on. This is the intention of the change after all, the problem is that radeon resumes the fbdev console layer _before_ restoring the display, through calling fb_set_suspend. And fbcon does an immediate ->set_par, which in turn causes the same forced mode restore to happen. Two concurrent modeset operations didn't lead to happiness. Fix this by delaying the fbcon resume until the end of the readeon resum functions. v2: Fix up a bit of the spelling fail.

While I play inhouse patches with much memory pressure on qemu-kvm, 3.14 kernel was randomly crashed. The reason was kernel stack overflow. When I investigated the problem, the callstack was a little bit deeper by involve with reclaim functions but not direct reclaim path. I tried to diet stack size of some functions related with alloc/reclaim so did a hundred of byte but overflow was't disappeard so that I encounter overflow by another deeper callstack on reclaim/allocator path. Of course, we might sweep every sites we have found for reducing stack usage but I'm not sure how long it saves the world(surely, lots of developer start to add nice features which will use stack agains) and if we consider another more complex feature in I/O layer and/or reclaim path, it might be better to increase stack size( meanwhile, stack usage on 64bit machine was doubled compared to 32bit while it have sticked to 8K. Hmm, it's not a fair to me and arm64 already expaned to 16K. ) So, my stupid idea is just let's expand stack size and keep an eye toward stack consumption on each kernel functions via stacktrace of ftrace. For example, we can have a bar like that each funcion shouldn't exceed 200K and emit the warning when some function consumes more in runtime. Of course, it could make false positive but at least, it could make a chance to think over it. I guess this topic was discussed several time so there might be strong reason not to increase kernel stack size on x86_64, for me not knowing so Ccing x86_64 maintainers, other MM guys and virtio maintainers. Here's an example call trace using up the kernel stack: Depth Size Location (51 entries) ----- ---- -------- 0) 7696 16 lookup_address 1) 7680 16 _lookup_address_cpa.isra.3 2) 7664 24 __change_page_attr_set_clr 3) 7640 392 kernel_map_pages 4) 7248 256 get_page_from_freelist 5) 6992 352 __alloc_pages_nodemask 6) 6640 8 alloc_pages_current 7) 6632 168 new_slab 8) 6464 8 __slab_alloc 9) 6456 80 __kmalloc 10) 6376 376 vring_add_indirect 11) 6000 144 virtqueue_add_sgs 12) 5856 288 __virtblk_add_req 13) 5568 96 virtio_queue_rq 14) 5472 128 __blk_mq_run_hw_queue 15) 5344 16 blk_mq_run_hw_queue 16) 5328 96 blk_mq_insert_requests 17) 5232 112 blk_mq_flush_plug_list 18) 5120 112 blk_flush_plug_list 19) 5008 64 io_schedule_timeout 20) 4944 128 mempool_alloc 21) 4816 96 bio_alloc_bioset 22) 4720 48 get_swap_bio 23) 4672 160 __swap_writepage 24) 4512 32 swap_writepage 25) 4480 320 shrink_page_list 26) 4160 208 shrink_inactive_list 27) 3952 304 shrink_lruvec 28) 3648 80 shrink_zone 29) 3568 128 do_try_to_free_pages 30) 3440 208 try_to_free_pages 31) 3232 352 __alloc_pages_nodemask 32) 2880 8 alloc_pages_current 33) 2872 200 __page_cache_alloc 34) 2672 80 find_or_create_page 35) 2592 80 ext4_mb_load_buddy 36) 2512 176 ext4_mb_regular_allocator 37) 2336 128 ext4_mb_new_blocks 38) 2208 256 ext4_ext_map_blocks 39) 1952 160 ext4_map_blocks 40) 1792 384 ext4_writepages 41) 1408 16 do_writepages 42) 1392 96 __writeback_single_inode 43) 1296 176 writeback_sb_inodes 44) 1120 80 __writeback_inodes_wb 45) 1040 160 wb_writeback 46) 880 208 bdi_writeback_workfn 47) 672 144 process_one_work 48) 528 112 worker_thread 49) 416 240 kthread 50) 176 176 ret_from_fork [ Note: the problem is exacerbated by certain gcc versions that seem to generate much bigger stack frames due to apparently bad coalescing of temporaries and generating too many spills. Rusty saw gcc-4.6.4 using 35% more stack on the virtio path than 4.8.2 does, for example. Minchan not only uses such a bad gcc version (4.6.3 in his case), but some of the stack use is due to debugging (CONFIG_DEBUG_PAGEALLOC is what causes that kernel_map_pages() frame, for example). But we're clearly getting too close. The VM code also seems to have excessive stack frames partly for the same compiler reason, triggered by excessive inlining and lots of function arguments. We need to improve on our stack use, but in the meantime let's do this simple stack increase too. Unlike most earlier reports, there is nothing simple that stands out as being really horribly wrong here, apart from the fact that the stack frames are just bigger than they should need to be. - Linus ] Signed-off-by: NMinchan Kim <minchan@kernel.org> Cc: Peter Anvin <hpa@zytor.com> Cc: Dave Chinner <david@fromorbit.com> Cc: Dave Jones <davej@redhat.com> Cc: Jens Axboe <axboe@kernel.dk> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Mel Gorman <mgorman@suse.de> Cc: Rik van Riel <riel@redhat.com> Cc: Johannes Weiner <hannes@cmpxchg.org> Cc: Hugh Dickins <hughd@google.com> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Michael S Tsirkin <mst@redhat.com> Cc: Dave Hansen <dave.hansen@intel.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: PJ Waskiewicz <pjwaskiewicz@gmail.com> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
