Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.11 cycle Core changes: - Augment fwnode_get_named_gpiod() to configure the GPIO pin immediately after requesting it like all other APIs do. This is a treewide change also updating all users. - Pass a GPIO label down to gpiod_request() from fwnode_get_named_gpiod(). This makes debugfs and the userspace ABI correctly reflect the current in-kernel consumer of a pin taken using this abstraction. This is a treewide change also updating all users. - Rename devm_get_gpiod_from_child() to devm_fwnode_get_gpiod_from_child() to reflect the fact that this function is operating on a fwnode object. This is a treewide change also updating all users. - Make it possible to take multiple GPIOs in a single hog of device tree hogs. - The refactorings switching GPIO chips to use the .set_config() callback using standard pin control properties and providing a backend into the pin control subsystem that were also merged into the pin control tree naturally appear here too. Testing instrumentation: - A whole slew of cleanups and improvements to the mockup GPIO driver. We now have an extended userspace test exercising the subsystem, and we can inject interrupts etc from userspace to fully test the core GPIO functionality. New drivers: - New driver for the Cortina Systems Gemini GPIO controller. - New driver for the Exar XR17V352/354/358 chips. - New driver for the ACCES PCI-IDIO-16 PCI GPIO card. Driver changes: - RCAR: set the irqchip parent device, add fine-grained runtime PM support. - pca953x: support optional RESET control line on the chip. - DaVinci: cleanups and simplifications. Add support for multiple instances. - .set_multiple() and naming of lines on more or less all of the ISA/PCI GPIO controllers. - mcp23s08: refactored to use regmap as a first step to further rewrites and modernizations" * tag 'gpio-v4.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (61 commits) gpio: reintroduce devm_get_gpiod_from_child() gpio: pci-idio-16: Fix PCI BAR index gpio: pci-idio-16: Fix PCI device ID code gpio: mockup: implement event injecting over debugfs gpio: mockup: add a dummy irqchip gpio: mockup: implement naming the lines gpio: mockup: code shrink gpio: mockup: readability tweaks gpio: Add GPIO support for the ACCES PCI-IDIO-16 gpio: Add the devm_fwnode_get_index_gpiod_from_child() helper gpio: Rename devm_get_gpiod_from_child() gpio: mcp23s08: Select REGMAP/REGMAP_I2C to fix build error gpio: ws16c48: Add support for GPIO names gpio: gpio-mm: Add support for GPIO names gpio: 104-idio-16: Add support for GPIO names gpio: 104-idi-48: Add support for GPIO names gpio: 104-dio-48e: Add support for GPIO names gpio: ws16c48: Remove unnecessary driver_data set gpio: gpio-mm: Remove unnecessary driver_data set gpio: 104-idio-16: Remove unnecessary driver_data set ...

Pull printk updates from Petr Mladek: - Add Petr Mladek, Sergey Senozhatsky as printk maintainers, and Steven Rostedt as the printk reviewer. This idea came up after the discussion about printk issues at Kernel Summit. It was formulated and discussed at lkml[1]. - Extend a lock-less NMI per-cpu buffers idea to handle recursive printk() calls by Sergey Senozhatsky[2]. It is the first step in sanitizing printk as discussed at Kernel Summit. The change allows to see messages that would normally get ignored or would cause a deadlock. Also it allows to enable lockdep in printk(). This already paid off. The testing in linux-next helped to discover two old problems that were hidden before[3][4]. - Remove unused parameter by Sergey Senozhatsky. Clean up after a past change.

At present, Tying the first_num size to NCHUNKS_ORDER is confusing. the number of chunks is completely unrelated to the number of buddies. The patch limits the first_num to actual range of possible buddy indexes. and that is more reasonable and obvious without functional change.

We had a deprecated_attr_warn() warning for 2 years and now the time has come and we finally can do the cleanup. The plan was as follows: : per-stat sysfs attributes are considered to be deprecated. : The basic strategy is: : -- the existing RW nodes will be downgraded to WO nodes (in linux 4.11) : -- deprecated RO sysfs nodes will eventually be removed (in linux 4.11) : : The list of deprecated attributes can be found here: : Documentation/ABI/obsolete/sysfs-block-zram : : Basically, every attribute that has its own read accessible sysfs : node (e.g. num_reads) *AND* is accessible via one of the stat files : (zram<id>/stat or zram<id>/io_stat or zram<id>/mm_stat) is considered : to be deprecated. The patch also removes `obsolete/sysfs-block-zram', clean ups `testing/sysfs-block-zram' and tweaks zram.txt files.

The patch "mm, page_alloc: warn_alloc print nodemask" implicitly sets the allocation nodemask to cpuset_current_mems_allowed when there is no effective mempolicy. cpuset_current_mems_allowed is only effective when cpusets are enabled, which is also printed by warn_alloc(), so setting the nodemask to cpuset_current_mems_allowed is redundant and prevents debugging issues where ac->nodemask is not set properly in the page allocator. This provides better debugging output since cpuset_print_current_mems_allowed() is already provided.

Now that __GFP_NOFAIL doesn't override decisions to skip the oom killer we are left with requests which require to loop inside the allocator without invoking the oom killer (e.g. GFP_NOFS|__GFP_NOFAIL used by fs code) and so they might, in very unlikely situations, loop for ever - e.g. other parallel request could starve them. This patch tries to limit the likelihood of such a lockup by giving these __GFP_NOFAIL requests a chance to move on by consuming a small part of memory reserves. We are using ALLOC_HARDER which should be enough to prevent from the starvation by regular allocation requests, yet it shouldn't consume enough from the reserves to disrupt high priority requests (ALLOC_HIGH). While we are at it, let's introduce a helper __alloc_pages_cpuset_fallback which enforces the cpusets but allows to fallback to ignore them if the first attempt fails. __GFP_NOFAIL requests can be considered important enough to allow cpuset runaway in order for the system to move on. It is highly unlikely that any of these will be GFP_USER anyway. Link: http://lkml.kernel.org/r/20161220134904.21023-4-mhocko@kernel.org Signed-off-by:

__alloc_pages_may_oom makes sure to skip the OOM killer depending on the allocation request. This includes lowmem requests, costly high order requests and others. For a long time __GFP_NOFAIL acted as an override for all those rules. This is not documented and it can be quite surprising as well. E.g. GFP_NOFS requests are not invoking the OOM killer but GFP_NOFS|__GFP_NOFAIL does so if we try to convert some of the existing open coded loops around allocator to nofail request (and we have done that in the past) then such a change would have a non trivial side effect which is far from obvious. Note that the primary motivation for skipping the OOM killer is to prevent from pre-mature invocation. The exception has been added by commit 82553a93 ("oom: invoke oom killer for __GFP_NOFAIL"). The changelog points out that the oom killer has to be invoked otherwise the request would be looping for ever. But this argument is rather weak because the OOM killer doesn't really guarantee a forward progress for those exceptional cases: - it will hardly help to form costly order which in turn can result in the system panic because of no oom killable task in the end - I believe we certainly do not want to put the system down just because there is a nasty driver asking for order-9 page with GFP_NOFAIL not realizing all the consequences. It is much better this request would loop for ever than the massive system disruption - lowmem is also highly unlikely to be freed during OOM killer - GFP_NOFS request could trigger while there is still a lot of memory pinned by filesystems. This patch simply removes the __GFP_NOFAIL special case in order to have a more clear semantic without surprising side effects. Signed-off-by:

Tetsuo Handa has pointed out that commit 0a0337e0 ("mm, oom: rework oom detection") has subtly changed semantic for costly high order requests with __GFP_NOFAIL and withtout __GFP_REPEAT and those can fail right now. My code inspection didn't reveal any such users in the tree but it is true that this might lead to unexpected allocation failures and subsequent OOPs. __alloc_pages_slowpath wrt. GFP_NOFAIL is hard to follow currently. There are few special cases but we are lacking a catch all place to be sure we will not miss any case where the non failing allocation might fail. This patch reorganizes the code a bit and puts all those special cases under nopage label which is the generic go-to-fail path. Non failing allocations are retried or those that cannot retry like non-sleeping allocation go to the failure point directly. This should make the code flow much easier to follow and make it less error prone for future changes. While we are there we have to move the stall check up to catch potentially looping non-failing allocations.

show_mem() allows to filter out node specific data which is irrelevant to the allocation request via SHOW_MEM_FILTER_NODES. The filtering is done in skip_free_areas_node which skips all nodes which are not in the mems_allowed of the current process. This works most of the time as expected because the nodemask shouldn't be outside of the allocating task but there are some exceptions. E.g. memory hotplug might want to request allocations from outside of the allowed nodes (see new_node_page). Get rid of this hardcoded behavior and push the allocation mask down the show_mem path and use it instead of cpuset_current_mems_allowed. NULL nodemask is interpreted as cpuset_current_mems_allowed.

We have a generic implementation for quite some time already. If there is any arch specific information to be printed then we should add a callback called from the generic code rather than duplicate the whole show_mem. The current code has resulted in the code duplication and the output divergence which is both confusing and adds maintainance costs. Let's just get rid of this mess.

Patch series "show_mem updates", v2. This is a mixture of one bug fix (patch 1), an enhancement (patch 2) and cleanups (the rest of the series). First two patches should be really straightforward. Patch 3 removes some arch specific show_mem implementations because I think they are quite outdated and do not really serve any useful purpose anymore. I think we should really strive to have a consistent show_mem output regardless of the architecture. If some architecture is really special and wants to dump something additional we should do that via an arch specific hook. The last patch adds nodemask parameter so that we do not rely on the hardcoded mems_allowed of the current task when doing the node filtering. I consider this more a cleanup than a fix because basically all users use a nodemask which is a subset of mems_allowed. There is only one call path in the memory hotplug which doesn't comply with this but that is hardly something to worry about. This patch (of 4): Commit 599d0c95 ("mm, vmscan: move LRU lists to node") has added per numa node statistics to show_mem but it forgot to add skip_free_areas_node to filter out nodes which are outside of the allocating task numa policy. Add this check to not pollute the output with the pointless information. Link: http://lkml.kernel.org/r/20170117091543.25850-2-mhocko@kernel.org Signed-off-by:
