The reports sent from some touch devices (e.g. the Cintiq 24HDT) contain junk data in the contact slots which follow the final "valid" contact. To avoid forwarding it to usrspace, we store the reported contact count during the pre-process phase and then only process that many contacts. If a device sends its contacts across multiple reports (what Microsoft refers to as "hybrid" mode) then the contact count will be zero for reports other than the first.

In some cases, we need access to information before it becomes available to the 'event' handler. In particular, for some devices we cannot properly process the finger data without first knowing the "contact count" at the very end of the report (e.g. the Cintiq 24HDT touch screen, when forced through the GENERIC codepath). Since the HID subsystem doesn't provide a way to take action before 'event' is called, we take a cue from hid-multitouch.c and add a pre-process step within the 'report' handler that performs the same function.

Allocated input devices should not use the 'pen_name' by default since we do not know at that point in time if that is an appropriate choice of name. Instead, use the (tool-agnostic) name that is stored in the device's 'wacom_features' structure. This also has the nice side-effect of requring us to be explicit about the naming of the pen device, as we already are for touch and pad devices.

The 'wacom_allocate_inputs' function tries to allocate three input devices: one each for the pen, touch, and pad. The pointers that are returned by the 'wacom_allocate_input' calls are temporarily stored to local variables where they are checked to ensure they're non-null before storing them in the 'wacom_wac' structure. If an allocation fails, the 'wacom_free_inputs' function is called to reclaim the memory. Unfortunately, 'wacom_free_inputs' is called prior to the pointers being copied, so it is not actually able to free anything. This patch has the calls to 'wacom_allocate_input' store the pointer directly in the 'wacom_wac' structure where they can be freed. Also, it replaces the call to 'wacom_free_inputs' with the (more general) 'wacom_clean_inputs' and removes the no-longer-used function.

As mentioned in the comment in the code, both the pen and touch data come from the interface tagged as BAMBOO_PAD. The driver re-routes the events for the Pen to the generic HID interface and keeps the ones for the touch through this current interface. Clearing the WACOM_DEVICETYPE_PEN bit removes the extra unused interface added in 2a6cdbdd ("HID: wacom: Introduce new 'touch_input' device") and makes the Bamboo PAD to behave like in 4.1.

The input_free_device() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed.

Pull x86 core updates from Ingo Molnar: "There were so many changes in the x86/asm, x86/apic and x86/mm topics in this cycle that the topical separation of -tip broke down somewhat - so the result is a more traditional architecture pull request, collected into the 'x86/core' topic. The topics were still maintained separately as far as possible, so bisectability and conceptual separation should still be pretty good - but there were a handful of merge points to avoid excessive dependencies (and conflicts) that would have been poorly tested in the end. The next cycle will hopefully be much more quiet (or at least will have fewer dependencies). The main changes in this cycle were: * x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas Gleixner) - This is the second and most intrusive part of changes to the x86 interrupt handling - full conversion to hierarchical interrupt domains: [IOAPIC domain] ----- | [MSI domain] --------[Remapping domain] ----- [ Vector domain ] | (optional) | [HPET MSI domain] ----- | | [DMAR domain] ----------------------------- | [Legacy domain] ----------------------------- This now reflects the actual hardware and allowed us to distangle the domain specific code from the underlying parent domain, which can be optional in the case of interrupt remapping. It's a clear separation of functionality and removes quite some duct tape constructs which plugged the remap code between ioapic/msi/hpet and the vector management. - Intel IOMMU IRQ remapping enhancements, to allow direct interrupt injection into guests (Feng Wu) * x86/asm changes: - Tons of cleanups and small speedups, micro-optimizations. This is in preparation to move a good chunk of the low level entry code from assembly to C code (Denys Vlasenko, Andy Lutomirski, Brian Gerst) - Moved all system entry related code to a new home under arch/x86/entry/ (Ingo Molnar) - Removal of the fragile and ugly CFI dwarf debuginfo annotations. Conversion to C will reintroduce many of them - but meanwhile they are only getting in the way, and the upstream kernel does not rely on them (Ingo Molnar) - NOP handling refinements. (Borislav Petkov) * x86/mm changes: - Big PAT and MTRR rework: making the code more robust and preparing to phase out exposing direct MTRR interfaces to drivers - in favor of using PAT driven interfaces (Toshi Kani, Luis R Rodriguez, Borislav Petkov) - New ioremap_wt()/set_memory_wt() interfaces to support Write-Through cached memory mappings. This is especially important for good performance on NVDIMM hardware (Toshi Kani) * x86/ras changes: - Add support for deferred errors on AMD (Aravind Gopalakrishnan) This is an important RAS feature which adds hardware support for poisoned data. That means roughly that the hardware marks data which it has detected as corrupted but wasn't able to correct, as poisoned data and raises an APIC interrupt to signal that in the form of a deferred error. It is the OS's responsibility then to take proper recovery action and thus prolonge system lifetime as far as possible. - Add support for Intel "Local MCE"s: upcoming CPUs will support CPU-local MCE interrupts, as opposed to the traditional system- wide broadcasted MCE interrupts (Ashok Raj) - Misc cleanups (Borislav Petkov) * x86/platform changes: - Intel Atom SoC updates ... and lots of other cleanups, fixlets and other changes - see the shortlog and the Git log for details" * 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (222 commits) x86/hpet: Use proper hpet device number for MSI allocation x86/hpet: Check for irq==0 when allocating hpet MSI interrupts x86/mm/pat, drivers/infiniband/ipath: Use arch_phys_wc_add() and require PAT disabled x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled x86/platform/intel/baytrail: Add comments about why we disabled HPET on Baytrail genirq: Prevent crash in irq_move_irq() genirq: Enhance irq_data_to_desc() to support hierarchy irqdomain iommu, x86: Properly handle posted interrupts for IOMMU hotplug iommu, x86: Provide irq_remapping_cap() interface iommu, x86: Setup Posted-Interrupts capability for Intel iommu iommu, x86: Add cap_pi_support() to detect VT-d PI capability iommu, x86: Avoid migrating VT-d posted interrupts iommu, x86: Save the mode (posted or remapped) of an IRTE iommu, x86: Implement irq_set_vcpu_affinity for intel_ir_chip iommu: dmar: Provide helper to copy shared irte fields iommu: dmar: Extend struct irte for VT-d Posted-Interrupts iommu: Add new member capability to struct irq_remap_ops x86/asm/entry/64: Disentangle error_entry/exit gsbase/ebx/usermode code x86/asm/entry/32: Shorten __audit_syscall_entry() args preparation x86/asm/entry/32: Explain reloading of registers after __audit_syscall_entry() ...

Pull x86 FPU updates from Ingo Molnar: "This tree contains two main changes: - The big FPU code rewrite: wide reaching cleanups and reorganization that pulls all the FPU code together into a clean base in arch/x86/fpu/. The resulting code is leaner and faster, and much easier to understand. This enables future work to further simplify the FPU code (such as removing lazy FPU restores). By its nature these changes have a substantial regression risk: FPU code related bugs are long lived, because races are often subtle and bugs mask as user-space failures that are difficult to track back to kernel side backs. I'm aware of no unfixed (or even suspected) FPU related regression so far. - MPX support rework/fixes.
