If noone listens to the input device when a tool comes in proximity, the tablet does not send the in-prox event when a client becomes available. That means that no events will be sent until the tool is taken out of proximity. In this situation, ask for the report WACOM_REPORT_INTUOSREAD which will read the corresponding feature and generate an in-prox event. To make some generation of hardware working, we need to unset the quirk NO_GET set by hid-core because the interfaces are seen as "boot mouse". We don't schedule this read in a worker while we are in an IO interrupt. We know that usbhid will do it asynchronously. If this is triggered by uhid, then this is obviously a client side bug :) Signed-off-by: NBenjamin Tissoires <benjamin.tissoires@redhat.com> Acked-by: NJason Gerecke <killertofu@gmail.com> Signed-off-by: NJiri Kosina <jkosina@suse.cz>

Declare the POWER_SUPPLY_PROP_PRESENT property to provide userspace with a way to determine if the battery on a wireless tablet is plugged in. Although current wireless tablets do not explicitly report this information, it can be inferred from other state information. In particular, a battery is assumed to be present if any of the following are true: a non-zero battery level reported, the battery is reported as charging, or the tablet is operating wirelessly. Note: The last condition above may not strictly hold for the Graphire Wireless (it charges from a DC barrel jack instead of a USB port), but I do not know what is reported in the no-battery condition.

The status packet for tablets which can use a wireless module contains a bit that is set if the battery is charging. This bit will be 0 if either a battery is not present or if the battery has reached full charge.

Tablets like the Intuos, Intuos Pro, and Bamboo have a connector for an optional wireless module that can be connected on the fly. The presence (or absence) of this module is indicated in a status report recieved from the tablet.

The stylus of this device works just fine out of the box. The touch is seen by default as a mouse with relative events and some gestures. The wireless and the wired version have slightly different firmwares, but the debug mode 2 on the feature 2 is common to the 2 devices. In this mode, all the reports are emitted through the debug interface (pen, raw touch and mouse emulation), so we have to re-route manually the events. We keep the Pen interface as a HID_GENERIC one because it works, and only parse the raw touches while discarding the mouse emulation & gestures. Switching the default in raw mode allows us to have a consistent user experience accross all the multitouch touchpads (and enable the touch part of the devices). Note that the buttons of this devices are reported through the touch interface. There is no 'Pad' interface. It seemed more natural to have the BTN_LEFT and BTN_RIGHT reported with the touch because they are placed under the touch interface and it looks like they belong to the touch part.

The Bamboo PAD in debug mode needs to re-route events from the debug interface to the Pen interface. This can be easily done with hid_input_report(), but that means that we need to keep a reference to the various hid_devices. There should be only one touch and one pen interface per physical tablet, so there is no need to keep a list of hid-devices, plain pointers are sufficient.

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 ...

Still, the majority of changes here are reworks of existing code to make it more straightforward or to prepare it for implementing new features on top of it. The primary example is the rework of ACPI resources handling from Jiang Liu, Thomas Gleixner and Lv Zheng with support for IOAPIC hotplug implemented on top of it, but there is quite a number of changes of this kind in the cpufreq core, ACPICA, ACPI EC driver, ACPI processor driver and the generic power domains core code too.

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.

hugetlb_treat_as_movable declared as unsigned long, but proc_dointvec() used for parsing it: static struct ctl_table vm_table[] = { ... { .procname = "hugepages_treat_as_movable", .data = &hugepages_treat_as_movable, .maxlen = sizeof(int), .mode = 0644, .proc_handler = proc_dointvec, }, This seems harmless, but it's better to use int type here.

Commit ed4d4902 ("mm, hugetlb: remove hugetlb_zero and hugetlb_infinity") replaced 'unsigned long hugetlb_zero' with 'int zero' leading to out-of-bounds access in proc_doulongvec_minmax(). Use '.extra1 = NULL' instead of '.extra1 = &zero'. Passing NULL is equivalent to passing minimal value, which is 0 for unsigned types.

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: NJohannes Weiner <hannes@cmpxchg.org> Acked-by: NKirill A.

Shared anonymous mmaps are implemented with shmem files, so all VMAs with shared writable semantics also have an underlying backing file.
