The Akai MIDImix (09e8:0031) is a MIDI fader controller that speaks regular MIDI and works well with Linux. However, initialization gets delayed due to reports timeout: [3643645.631124] hid-generic 0003:09E8:0031.0020: timeout initializing reports [3643645.632416] hid-generic 0003:09E8:0031.0020: hiddev0: USB HID v1.11 Device [AKAI MIDI Mix] on usb-0000:00:14.0-2/input0 Adding "usbhid.quirks=0x09e8:0x0031:0x20000000" on the kernel command line makes the issues go away.

This reverts commit 18339f59 ("HID: dragonrise: fix HID...") because it breaks certain dragonrise 0079:0006 gamepads. While it may fix a breakage caused by commit 79346d62 ("HID: input: force generic axis to be mapped to their user space axis"), it is probable that the manufacturer released different hardware with the same PID so this fix works for only a subset and breaks the other gamepads sharing the PID. What is needed is another more generic solution which fixes 79346d62 ("HID: input: force generic axis ...") breakage for this controller: we need to add an exception for this driver to make it keep the old behaviour previous to the initial breakage (this is done in patch 2 of this series).

Commit 79346d62 ("HID: input: force generic axis to be mapped to their user space axis") made mapping generic axes to their userspace equivalents mandatory and some lower end gamepads which were depending on the previous behaviour suffered severe regressions because they were reusing axes and expecting hid-input to multiplex their map to the respective userspace axis by always searching for and using the next available axis. One solution is to add a hid quirk for this type of "previous" behaviour in hid-input to bypass the new axes policy in favour of the old one, but since only one hardware vendor seems to be affected negatively we're better off making and exception and mapping in the driver for now; if more vendors or drivers turn out to experience the problem we should reconsider the quirk solution.

Pull HID updates from Jiri Kosina: - Integrated Sensor Hub support (Cherrytrail+) from Srinivas Pandruvada - Big cleanup of Wacom driver; namely it's now using devres, and the standardized LED API so that libinput doesn't need to have root access any more, with substantial amount of other cleanups piggy-backing on top. All this from Benjamin Tissoires - Report descriptor parsing would now ignore and out-of-range System controls in case of the application actually being System Control. This fixes quite some issues with several devices, and allows us to remove a few ->report_fixup callbacks.

Pull namespace updates from Eric Biederman: "This set of changes is a number of smaller things that have been overlooked in other development cycles focused on more fundamental change. The devpts changes are small things that were a distraction until we managed to kill off DEVPTS_MULTPLE_INSTANCES. There is an trivial regression fix to autofs for the unprivileged mount changes that went in last cycle. A pair of ioctls has been added by Andrey Vagin making it is possible to discover the relationships between namespaces when referring to them through file descriptors. The big user visible change is starting to add simple resource limits to catch programs that misbehave. With namespaces in general and user namespaces in particular allowing users to use more kinds of resources, it has become important to have something to limit errant programs. Because the purpose of these limits is to catch errant programs the code needs to be inexpensive to use as it always on, and the default limits need to be high enough that well behaved programs on well behaved systems don't encounter them. To this end, after some review I have implemented per user per user namespace limits, and use them to limit the number of namespaces. The limits being per user mean that one user can not exhause the limits of another user. The limits being per user namespace allow contexts where the limit is 0 and security conscious folks can remove from their threat anlysis the code used to manage namespaces (as they have historically done as it root only). At the same time the limits being per user namespace allow other parts of the system to use namespaces. Namespaces are increasingly being used in application sand boxing scenarios so an all or nothing disable for the entire system for the security conscious folks makes increasing use of these sandboxes impossible. There is also added a limit on the maximum number of mounts present in a single mount namespace. It is nontrivial to guess what a reasonable system wide limit on the number of mount structure in the kernel would be, especially as it various based on how a system is using containers. A limit on the number of mounts in a mount namespace however is much easier to understand and set. In most cases in practice only about 1000 mounts are used. Given that some autofs scenarious have the potential to be 30,000 to 50,000 mounts I have set the default limit for the number of mounts at 100,000 which is well above every known set of users but low enough that the mount hash tables don't degrade unreaonsably. These limits are a start. I expect this estabilishes a pattern that other limits for resources that namespaces use will follow. There has been interest in making inotify event limits per user per user namespace as well as interest expressed in making details about what is going on in the kernel more visible" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (28 commits) autofs: Fix automounts by using current_real_cred()->uid mnt: Add a per mount namespace limit on the number of mounts netns: move {inc,dec}_net_namespaces into #ifdef nsfs: Simplify __ns_get_path tools/testing: add a test to check nsfs ioctl-s nsfs: add ioctl to get a parent namespace nsfs: add ioctl to get an owning user namespace for ns file descriptor kernel: add a helper to get an owning user namespace for a namespace devpts: Change the owner of /dev/pts/ptmx to the mounter of /dev/pts devpts: Remove sync_filesystems devpts: Make devpts_kill_sb safe if fsi is NULL devpts: Simplify devpts_mount by using mount_nodev devpts: Move the creation of /dev/pts/ptmx into fill_super devpts: Move parse_mount_options into fill_super userns: When the per user per user namespace limit is reached return ENOSPC userns; Document per user per user namespace limits. mntns: Add a limit on the number of mount namespaces. netns: Add a limit on the number of net namespaces cgroupns: Add a limit on the number of cgroup namespaces ipcns: Add a limit on the number of ipc namespaces ...

Pull xfs and iomap updates from Dave Chinner: "The main things in this update are the iomap-based DAX infrastructure, an XFS delalloc rework, and a chunk of fixes to how log recovery schedules writeback to prevent spurious corruption detections when recovery of certain items was not required. The other main chunk of code is some preparation for the upcoming reflink functionality. Most of it is generic and cleanups that stand alone, but they were ready and reviewed so are in this pull request. Speaking of reflink, I'm currently planning to send you another pull request next week containing all the new reflink functionality. I'm working through a similar process to the last cycle, where I sent the reverse mapping code in a separate request because of how large it was. The reflink code merge is even bigger than reverse mapping, so I'll be doing the same thing again....

Early during boot topology_update_package_map() computes logical_pkg_ids for all present processors. Later, when processors are brought up, identify_cpu() updates these values based on phys_pkg_id which is a function of initial_apicid. On PV guests the latter may point to a non-existing node, causing logical_pkg_ids to be set to -1. Intel's RAPL uses logical_pkg_id (as topology_logical_package_id()) to index its arrays and therefore in this case will point to index 65535 (since logical_pkg_id is a u16). This could lead to either a crash or may actually access random memory location. As a workaround, we recompute topology during CPU bringup to reset logical_pkg_id to a valid value. (The reason for initial_apicid being bogus is because it is initial_apicid of the processor from which the guest is launched. This value is CPUID(1).EBX[31:24]) Signed-off-by:

Commit 215e362d ("ARM: 8306/1: loop_udelay: remove bogomips value limitation") tried to increase the bogomips limitation, but in doing so messed up udelay such that it always gives about a 5% error in the delay, even if we use a timer. The calculation is: loops = UDELAY_MULT * us_delay * ticks_per_jiffy >> UDELAY_SHIFT Originally, UDELAY_MULT was ((UL(2199023) * HZ) >> 11) and UDELAY_SHIFT 30. Assuming HZ=100, us_delay of 1000 and ticks_per_jiffy of 1660000 (eg, 166MHz timer, 1ms delay) this would calculate: ((UL(2199023) * HZ) >> 11) * 1000 * 1660000 >> 30 => 165999 With the new values of 2047 * HZ + 483648 * HZ / 1000000 and 31, we get: (2047 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31 => 158269 which is incorrect. This is due to a typo - correcting it gives: (2147 * HZ + 483648 * HZ / 1000000) * 1000 * 1660000 >> 31 => 165999 i.o.w, the original value.

Chris Hyser says: ==================== sparc64: PCIe performance enhancements Ver 2 is redone for 4.8 where commit 00085f1e changed DMA attributes from struct pointer to unsigned long. This set of patches initiates a series of PCIe performance enhancement patch submittals. Patch 1/2 enables version 2 of the SPARC sun4v IOMMU I/O address translation services need for subsequent enhancements. Patch 2/2 allows drivers to specify DMA_ATTR_WEAK_ORDERING via DMA attributes to the SPARC DMA mapping routines enabling "relaxed ordering" for the buffer being mapped.

Enable relaxed ordering for memory writes in IOMMU TSB entry from dma_4v_alloc_coherent(), dma_4v_map_page() and dma_4v_map_sg() when dma_attrs DMA_ATTR_WEAK_ORDERING is set. This requires PCI IOMMU I/O Translation Services version 2.0 API. Many PCIe devices allow enabling relaxed-ordering (memory writes bypassing other memory writes) for various DMA buffers. A notable exception is the Mellanox mlx4 IB adapter. Due to the nature of x86 HW this appears to have little performance impact there. On SPARC HW however, this results in major performance degradation getting only about 3Gbps. Enabling RO in the IOMMU entries corresponding to mlx4 data buffers increases the throughput to about 13 Gbps. Orabug: 19245907 Signed-off-by:
