HID Sensor Spec defines two usage ids for custom sensors HID_USAGE_SENSOR_TYPE_OTHER_CUSTOM (0x09, 0xE1) HID_USAGE_SENSOR_TYPE_OTHER_GENERIC(0x09, 0xE2) In addition the standard also defines usage ids for custom fields. The purpose of these sensors is to extend the functionality or provide a way to obfuscate the data being communicated by a sensor. Without knowing the mapping between the data and its encapsulated form, it is difficult for an driver to determine what data is being communicated by the sensor. This allows some differentiating use cases, where vendor can provide applications. Since these can't be represented by standard sensor interfaces like IIO, we present these as fields with - type (input/output) - units - min/max - get/set value In addition an dev interface to transfer report events. Details about this interface is described in /Documentation/hid/hid-sensor.txt. Manufacturers should not use these ids for any standard sensors, otherwise the the product/vendor id can be added to black list. Signed-off-by:

For defining enumeration values like report or power status events, the enumeration usage ids are enclosed in a logical collection. In this case we need to match logical usage id for pending read on this usage id. For example, in the below field, when read is requested for 0319, the report will contain one of the status usages like 850, 851 etc. In this case the raw event will not match 0319. So when logical collection matches, then wake up the pending thread. Physical(Sensor.OtherCustom) Logical(Sensor.0319) Application(Sensor.Sensor) Usage(6) Sensor.0850 Sensor.0851 Sensor.0852 Sensor.0853 Sensor.0854 Sensor.0855 Logical Minimum(1) Logical Maximum(5) Report Size(8) Report Count(1) Report Offset(24) Flags( Array Absolute ) Signed-off-by:

Add additional flag to read in async mode. In this mode the caller will get reply via registered callback for capture_sample. Callbacks can be registered using sensor_hub_register_callback function. The usage id parameter of the capture_sample can be matched with the usage id of the requested attribute. Signed-off-by:

Section 4.2.5 of HID Sensor hub specification allows two methods defining sensor devices. - Each sensor device by its own collection - A top level application collection object, including multiple sensors. In the first method, each sensor can be in its own sensor application collection without a physical collection. In the second method there is a usage id for collection type, which is defined as an application collection, with multiple physical collections in it. It is possible to define fusion sensor with this and may have its own handler. If there is a callback registered for the collection type, then forward all reports for sensors in its collection to this handler. Signed-off-by:

Current implementation only allows one outstanding synchronous read. This is a performance hit when user mode is requesting raw reads of sensor attributes on multiple sensors together. This change changes the mutex lock to per hid sensor hub device instead of global lock. Although request to hid sensor hub is serialized, there can be multiple outstanding read requests pending for responses via hid reports. Signed-off-by:

Commit 84683a7e ("sata_dwc_460ex: enable COMPILE_TEST for the driver") enabled this driver for non-ppc460-ex platforms, but it was then disabled for ARM and ARM64 by commit 2de5a9c0 ("sata_dwc_460ex: disable compilation on ARM and ARM64") because it's too noisy and broken. This disabled is entirely, because it's too noisy on x86-64 too, and there's no point in disabling architectures one by one. At a minimum, the code isn't 64-bit clean, and even on 32-bit it is questionable whether it makes sense.

Merge misc updates from Andrew Morton: "Bite-sized chunks this time, to avoid the MTA ratelimiting woes. - fs/notify updates - ocfs2 - some of MM" That laconic "some MM" is mainly the removal of remap_file_pages(), which is a big simplification of the VM, and which gets rid of a *lot* of random cruft and special cases because we no longer support the non-linear mappings that it used. From a user interface perspective, nothing has changed, because the remap_file_pages() syscall still exists, it's just done by emulating the old behavior by creating a lot of individual small mappings instead of one non-linear one. The emulation is slower than the old "native" non-linear mappings, but nobody really uses or cares about remap_file_pages(), and simplifying the VM is a big advantage. * emailed patches from Andrew Morton <akpm@linux-foundation.org>: (78 commits) memcg: zap memcg_slab_caches and memcg_slab_mutex memcg: zap memcg_name argument of memcg_create_kmem_cache memcg: zap __memcg_{charge,uncharge}_slab mm/page_alloc.c: place zone_id check before VM_BUG_ON_PAGE check mm: hugetlb: fix type of hugetlb_treat_as_movable variable mm, hugetlb: remove unnecessary lower bound on sysctl handlers"? mm: memory: merge shared-writable dirtying branches in do_wp_page() mm: memory: remove ->vm_file check on shared writable vmas xtensa: drop _PAGE_FILE and pte_file()-related helpers x86: drop _PAGE_FILE and pte_file()-related helpers unicore32: drop pte_file()-related helpers um: drop _PAGE_FILE and pte_file()-related helpers tile: drop pte_file()-related helpers sparc: drop pte_file()-related helpers sh: drop _PAGE_FILE and pte_file()-related helpers score: drop _PAGE_FILE and pte_file()-related helpers s390: drop pte_file()-related helpers parisc: drop _PAGE_FILE and pte_file()-related helpers openrisc: drop _PAGE_FILE and pte_file()-related helpers nios2: drop _PAGE_FILE and pte_file()-related helpers ... -

mem_cgroup->memcg_slab_caches is a list of kmem caches corresponding to the given cgroup. Currently, it is only used on css free in order to destroy all caches corresponding to the memory cgroup being freed. The list is protected by memcg_slab_mutex. The mutex is also used to protect kmem_cache->memcg_params->memcg_caches arrays and synchronizes kmem_cache_destroy vs memcg_unregister_all_caches. However, we can perfectly get on without these two. To destroy all caches corresponding to a memory cgroup, we can walk over the global list of kmem caches, slab_caches, and we can do all the synchronization stuff using the slab_mutex instead of the memcg_slab_mutex. This patch therefore gets rid of the memcg_slab_caches and memcg_slab_mutex. Apart from this nice cleanup, it also: - assures that rcu_barrier() is called once at max when a root cache is destroyed or a memory cgroup is freed, no matter how many caches have SLAB_DESTROY_BY_RCU flag set; - fixes the race between kmem_cache_destroy and kmem_cache_create that exists, because memcg_cleanup_cache_params, which is called from kmem_cache_destroy after checking that kmem_cache->refcount=0, releases the slab_mutex, which gives kmem_cache_create a chance to make an alias to a cache doomed to be destroyed.

If the freeing page and its buddy page are not at the same zone, the current holding zone->lock for the freeing page cann't prevent buddy page getting allocated, this could trigger VM_BUG_ON_PAGE in page_is_buddy() at a very tiny chance, such as: cpu 0: cpu 1: hold zone_1 lock check page and it buddy PageBuddy(buddy) is true hold zone_2 lock page_order(buddy) == order is true alloc buddy trigger VM_BUG_ON_PAGE(page_count(buddy) != 0) zone_1->lock prevents the freeing page getting allocated zone_2->lock prevents the buddy page getting allocated they are not the same zone->lock. If we can't remove the zone_id check statement, it's better handle this rare race. This patch fixes this by placing the zone_id check before the VM_BUG_ON_PAGE check. Signed-off-by:

Whether there is a vm_ops->page_mkwrite or not, the page dirtying is pretty much the same. Make sure the page references are the same in both cases, then merge the two branches. It's tempting to go even further and page-lock the !page_mkwrite case, to get it in line with everybody else setting the page table and thus further simplify the model. But that's not quite compelling enough to justify dropping the pte lock, then relocking and verifying the entry for filesystems without ->page_mkwrite, which notably includes tmpfs. Leave it for now and lock the page late in the !page_mkwrite case. Signed-off-by:
