46f781e0d1 HID: multitouch: fix sticky fingers
The sticky fingers quirk (MT_QUIRK_STICKY_FINGERS) was only considering
the case when slots were not released during the last report.
This can be problematic if the firmware forgets to release a finger
while others are still present.

This was observed on the Synaptics DLL0945 touchpad found on the Dell
XPS 9310 and the Dell Inspiron 5406.

aa4daea418 HID: multitouch: fix name of Stylus input devices
HID_DG_PEN devices should have a suffix of "Stylus", as pointed out by
commit c0ee1d5716 ("HID: hid-input: Add suffix also for HID_DG_PEN").
However, on multitouch devices, these suffixes may be overridden. Before
that commit, HID_DG_PEN devices would get the "Stylus" suffix, but after
that, multitouch would override them to have an "UNKNOWN" suffix. Just add
HID_DG_PEN to the list of non-overriden suffixes in multitouch.

Before this fix:

[    0.470981] input: ELAN9008:00 04F3:2E14 UNKNOWN as /devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-16/i2c-ELAN9008:00/0018:04F3:2E14.0001/input/input8
ELAN9008:00 04F3:2E14 UNKNOWN

After this fix:

[    0.474332] input: ELAN9008:00 04F3:2E14 Stylus as /devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-16/i2c-ELAN9008:00/0018:04F3:2E14.0001/input/input8

0187c08058 HID: hid-input: only ignore 0 battery events for digitizers
Commit 581c448476 ("HID: input: map digitizer battery usage") added
handling of battery events for digitizers (typically for batteries
presented in stylii). Digitizers typically report correct battery levels
only when stylus is actively touching the surface, and in other cases
they may report battery level of 0. To avoid confusing consumers of the
battery information the code was added to filer out reports with 0
battery levels.

However there exist other kinds of devices that may legitimately report
0 battery levels. Fix this by filtering out 0-level reports only for
digitizer usages, and continue reporting them for other kinds of devices
(Smart Batteries, etc).

083a4f3f3c HID: Kconfig: Fix build error from CONFIG_HID_HAPTIC
Temporarily change CONFIG_HID_HAPTIC to be bool instead of tristate, until
we implement a permanent solution.

Recently the CONFIG_HID_HAPTIC Kconfig option was reported as causing
the following build errors:

  MODPOST Module.symvers
ERROR: modpost: "hid_haptic_init" [drivers/hid/hid-multitouch.ko] undefined!
ERROR: modpost: "hid_haptic_pressure_increase" [drivers/hid/hid-multitouch.ko] undefined!

make[3]: *** [/home/thl/var/linux.dev/scripts/Makefile.modpost:147: Module.symvers] Error 1

when the kernel is compiled with the following configuration:

CONFIG_HID=y
CONFIG_HID_MULTITOUCH=m
CONFIG_HID_HAPTIC=m

To resolve this, temporarily change the CONFIG_HID_HAPTIC option to be
bool, until we arrive at a permanent solution to enable CONFIG_HID_HAPTIC
to be tristate.

For a more detailed discussion, see [1].

8fe2cd8ec8 HID: intel-thc-hid: Intel-quickspi: switch first interrupt from level to edge detection
The original implementation used level detection for the first interrupt
after device reset to avoid potential interrupt line noise and missed
interrupts during the initialization phase. However, this approach
introduced unintended side effects when tested with certain touch panels,
including:
 - Delayed hardware interrupt response
 - Multiple spurious interrupt triggers

Switching back to edge detection for the first interrupt resolves these
issues while maintaining reliable interrupt handling.

Extensive testing across multiple platforms with touch panels from
various vendors confirms this change introduces no regressions.

67da125e30 RCU pull request for v6.18
This pull request contains the following branches, non-octopus merged:
 
 Documentation updates:
 
   - Update whatisRCU.rst and checklist.rst for recent RCU API additions.
 
   - Fix RCU documentation formatting and typos.
 
   - Replace dead Ottawa Linux Symposium links in RTFP.txt.
 
 Miscellaneous RCU updates:
 
   - Document that rcu_barrier() hurries RCU_LAZY callbacks.
 
   - Remove redundant interrupt disabling from
     rcu_preempt_deferred_qs_handler().
 
   - Move list_for_each_rcu from list.h to rculist.h, and adjust the
     include directive in kernel/cgroup/dmem.c accordingly.
 
   - Make initial set of changes to accommodate upcoming system_percpu_wq
     changes.
 
 SRCU updates:
 
   - Create an srcu_read_lock_fast_notrace() for eventual use in tracing,
     including adding guards.
 
   - Document the reliance on per-CPU operations as implicit RCU readers
     in __srcu_read_{,un}lock_fast().
 
   - Document the srcu_flip() function's memory-barrier D's relationship
     to SRCU-fast readers.
 
   - Remove a redundant preempt_disable() and preempt_enable() pair from
     srcu_gp_start_if_needed().
 
 Torture-test updates:
 
   - Fix jitter.sh spin time so that it actually varies as advertised.
     It is still quite coarse-grained, but at least it does now vary.
 
   - Update torture.sh help text to include the not-so-new --do-normal
     parameter, which permits (for example) testing KCSAN kernels without
     doing non-debug kernels.
 
   - Fix a number of false-positive diagnostics that were being triggered
     by rcutorture starting before boot completed.  Running multiple
     near-CPU-bound rcutorture processes when there is only the boot CPU
     is after all a bit excessive.
 
   - Substitute kcalloc() for kzalloc().
 
   - Remove a redundant kfree() and NULL out kfree()ed objects.

86bcf7be1e RISC-V updates for the v6.18 merge window (part two)
Second set of RISC-V updates for the v6.18 merge window, consisting
 of:
 
 - Support for the RISC-V-standardized RPMI interface.
 
   RPMI is a platform management communication mechanism between OSes
   running on application processors, and a remote platform management
   processor.  Similar to ARM SCMI, TI SCI, etc.  This includes irqchip,
   mailbox, and clk changes.
 
 - Support for the RISC-V-standardized MPXY SBI extension.
 
   MPXY is a RISC-V-specific standard implementing a shared memory
   mailbox between S-mode operating systems (e.g., Linux) and M-mode
   firmware (e.g., OpenSBI).  It is part of this PR since one of its
   use cases is to enable M-mode firmware to act as a single RPMI client
   for all RPMI activity on a core (including S-mode RPMI activity).
   Includes a mailbox driver.
 
 - Some ACPI-related updates to enable the use of RPMI and MPXY.
 
 - The addition of Linux-wide memcpy_{from,to}_le32() static inline
   functions, for RPMI use.
 
 - An ACPI Kconfig change to enable boot logos on any ACPI-using
   architecture (including RISC-V)
 
 - A RISC-V defconfig change to add GPIO keyboard and event device
   support, for front panel shutdown or reboot buttons
 
 This PR also includes a recent, one-line Kconfig patch from Geert to
 keep non-RISC-V users from being asked about building the RPMI virtual
 clock driver when !COMPILE_TEST.  THere's nothing preventing
 non-RISC-V SoCs from implementing RPMI, but until some users show up,
 let's not annoy others with it.

Pull x86 entry updates from Dave Hansen:
 "A pair of x86/entry updates.

  The FRED one adjusts the kernel to the latest spec. The spec change
  prevents attackers from abusing kernel entry points.

  The second one came about because of the LASS work[1]. It moves the
  vsyscall emulation code away from depending on X86_PF_INSTR which is
  not available on some CPUs. Those CPUs are pretty obscure these days,
  but this still seems like the right thing to do. It also makes this
  code consistent with some things that the LASS code is going to do.

   - Remove ENDBR64 from FRED entry points"

f3826aa996 guest_memfd:
* Add support for host userspace mapping of guest_memfd-backed memory for VM
   types that do NOT use support KVM_MEMORY_ATTRIBUTE_PRIVATE (which isn't
   precisely the same thing as CoCo VMs, since x86's SEV-MEM and SEV-ES have
   no way to detect private vs. shared).
 
   This lays the groundwork for removal of guest memory from the kernel direct
   map, as well as for limited mmap() for guest_memfd-backed memory.
 
   For more information see:
   * a6ad54137a ("Merge branch 'guest-memfd-mmap' into HEAD", 2025-08-27)
   * https://github.com/firecracker-microvm/firecracker/tree/feature/secret-hiding
     (guest_memfd in Firecracker)
   * https://lore.kernel.org/all/20250221160728.1584559-1-roypat@amazon.co.uk/

   * https://lore.kernel.org/all/20250328153133.3504118-1-tabba@google.com/
     (mmap support)
 
 ARM:
 
 * Add support for FF-A 1.2 as the secure memory conduit for pKVM,
   allowing more registers to be used as part of the message payload.
 
 * Change the way pKVM allocates its VM handles, making sure that the
   privileged hypervisor is never tricked into using uninitialised
   data.
 
 * Speed up MMIO range registration by avoiding unnecessary RCU
   synchronisation, which results in VMs starting much quicker.
 
 * Add the dump of the instruction stream when panic-ing in the EL2
   payload, just like the rest of the kernel has always done. This will
   hopefully help debugging non-VHE setups.
 
 * Add 52bit PA support to the stage-1 page-table walker, and make use
   of it to populate the fault level reported to the guest on failing
   to translate a stage-1 walk.
 
 * Add NV support to the GICv3-on-GICv5 emulation code, ensuring
   feature parity for guests, irrespective of the host platform.
 
 * Fix some really ugly architecture problems when dealing with debug
   in a nested VM. This has some bad performance impacts, but is at
   least correct.
 
 * Add enough infrastructure to be able to disable EL2 features and
   give effective values to the EL2 control registers. This then allows
   a bunch of features to be turned off, which helps cross-host
   migration.
 
 * Large rework of the selftest infrastructure to allow most tests to
   transparently run at EL2. This is the first step towards enabling
   NV testing.
 
 * Various fixes and improvements all over the map, including one BE
   fix, just in time for the removal of the feature.
 
 LoongArch:
 
 * Detect page table walk feature on new hardware
 
 * Add sign extension with kernel MMIO/IOCSR emulation
 
 * Improve in-kernel IPI emulation
 
 * Improve in-kernel PCH-PIC emulation
 
 * Move kvm_iocsr tracepoint out of generic code
 
 RISC-V:
 
 * Added SBI FWFT extension for Guest/VM with misaligned delegation and
   pointer masking PMLEN features
 
 * Added ONE_REG interface for SBI FWFT extension
 
 * Added Zicbop and bfloat16 extensions for Guest/VM
 
 * Enabled more common KVM selftests for RISC-V
 
 * Added SBI v3.0 PMU enhancements in KVM and perf driver
 
 s390:
 
 * Improve interrupt cpu for wakeup, in particular the heuristic to decide
   which vCPU to deliver a floating interrupt to.
 
 * Clear the PTE when discarding a swapped page because of CMMA; this
   bug was introduced in 6.16 when refactoring gmap code.
 
 x86 selftests:
 
 * Add #DE coverage in the fastops test (the only exception that's guest-
   triggerable in fastop-emulated instructions).
 
 * Fix PMU selftests errors encountered on Granite Rapids (GNR), Sierra
   Forest (SRF) and Clearwater Forest (CWF).
 
 * Minor cleanups and improvements
 
 x86 (guest side):
 
 * For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when
   overriding guest MTRR for TDX/SNP to fix an issue where ACPI auto-mapping
   could map devices as WB and prevent the device drivers from mapping their
   devices with UC/UC-.
 
 * Make kvm_async_pf_task_wake() a local static helper and remove its
   export.
 
 * Use native qspinlocks when running in a VM with dedicated vCPU=>pCPU
   bindings even when PV_UNHALT is unsupported.
 
 Generic:
 
 * Remove a redundant __GFP_NOWARN from kvm_setup_async_pf() as __GFP_NOWARN is
   now included in GFP_NOWAIT.

           https://lore.kernel.org/all/20250328153133.3504118-1-tabba@google.com/

  ARM:

   - Add support for FF-A 1.2 as the secure memory conduit for pKVM,
     allowing more registers to be used as part of the message payload.

   - Change the way pKVM allocates its VM handles, making sure that the
     privileged hypervisor is never tricked into using uninitialised
     data.

   - Speed up MMIO range registration by avoiding unnecessary RCU
     synchronisation, which results in VMs starting much quicker.

   - Add the dump of the instruction stream when panic-ing in the EL2
     payload, just like the rest of the kernel has always done. This
     will hopefully help debugging non-VHE setups.

   - Add 52bit PA support to the stage-1 page-table walker, and make use
     of it to populate the fault level reported to the guest on failing
     to translate a stage-1 walk.

   - Add NV support to the GICv3-on-GICv5 emulation code, ensuring
     feature parity for guests, irrespective of the host platform.

   - Fix some really ugly architecture problems when dealing with debug
     in a nested VM. This has some bad performance impacts, but is at
     least correct.

   - Add enough infrastructure to be able to disable EL2 features and
     give effective values to the EL2 control registers. This then
     allows a bunch of features to be turned off, which helps cross-host
     migration.

   - Large rework of the selftest infrastructure to allow most tests to
     transparently run at EL2. This is the first step towards enabling
     NV testing.

   - Various fixes and improvements all over the map, including one BE
     fix, just in time for the removal of the feature.

  LoongArch:

   - Detect page table walk feature on new hardware

   - Add sign extension with kernel MMIO/IOCSR emulation

   - Improve in-kernel IPI emulation

   - Improve in-kernel PCH-PIC emulation

   - Move kvm_iocsr tracepoint out of generic code

  RISC-V:

   - Added SBI FWFT extension for Guest/VM with misaligned delegation
     and pointer masking PMLEN features

   - Added ONE_REG interface for SBI FWFT extension

   - Added Zicbop and bfloat16 extensions for Guest/VM

   - Enabled more common KVM selftests for RISC-V

   - Added SBI v3.0 PMU enhancements in KVM and perf driver

  s390:

   - Improve interrupt cpu for wakeup, in particular the heuristic to
     decide which vCPU to deliver a floating interrupt to.

   - Clear the PTE when discarding a swapped page because of CMMA; this
     bug was introduced in 6.16 when refactoring gmap code.

  x86 selftests:

   - Add #DE coverage in the fastops test (the only exception that's
     guest- triggerable in fastop-emulated instructions).

   - Fix PMU selftests errors encountered on Granite Rapids (GNR),
     Sierra Forest (SRF) and Clearwater Forest (CWF).

   - Minor cleanups and improvements

  x86 (guest side):

   - For the legacy PCI hole (memory between TOLUD and 4GiB) to UC when
     overriding guest MTRR for TDX/SNP to fix an issue where ACPI
     auto-mapping could map devices as WB and prevent the device drivers
     from mapping their devices with UC/UC-.

   - Make kvm_async_pf_task_wake() a local static helper and remove its
     export.

   - Use native qspinlocks when running in a VM with dedicated
     vCPU=>pCPU bindings even when PV_UNHALT is unsupported.

  Generic:

   - Remove a redundant __GFP_NOWARN from kvm_setup_async_pf() as
     __GFP_NOWARN is now included in GFP_NOWAIT.

a498d59c46 dma-mapping updates for Linux 6.18:
- refactoring of DMA mapping API to physical addresses as the primary
 interface instead of page+offset parameters; this gets much closer to
 Matthew Wilcox's long term wish for struct-pageless IO to cacheable DRAM and is
 supporting memdesc project which seeks to substantially transform how
 struct page works; an advantage of this approach is the possibility of
 introducing DMA_ATTR_MMIO, which covers existing 'dma_map_resource' flow
 in the common paths, what in turn lets to use recently introduced
 dma_iova_link() API to map PCI P2P MMIO without creating struct page;

 - Lots of build-infrastructure work, further cleaning up long-term
   kernel-doc technical debt.  The sphinx-pre-install tool has been
   converted to Python and updated for current systems.
 
 - A new tool to detect when documents have been moved and generate HTML

86d563ac5f f2fs-for-6.18-rc1
This release focuses on two primary updates for Android devices. First, it sets
 hash-based file name lookup as the default method to improve performance, while
 retaining an option to fall back to a linear lookup. Second, it resolves a
 persistent issue with the checkpoint=enable feature. The update further boosts
 performance by prefetching node blocks, merging FUA writes more efficiently, and
 optimizing block allocation policies.
 
 The release is rounded out by a comprehensive set of bug fixes that address
 memory safety, data integrity, and potential system hangs, along with minor
 documentation and code clean-ups.
 
 Enhancement:
  - add mount option and sysfs entry to tune the lookup mode
  - dump more information and add a timeout when enabling/disabling checkpoints
  - readahead node blocks in F2FS_GET_BLOCK_PRECACHE mode
  - merge FUA command with the existing writes
  - allocate HOT_DATA for IPU writes
  - Use allocate_section_policy to control write priority in multi-devices setups
  - add reserved nodes for privileged users
  - Add bggc_io_aware to adjust the priority of BG_GC when issuing IO
  - show the list of donation files
 
 Bug fix:
  - add missing dput() when printing the donation list
  - fix UAF issue in f2fs_merge_page_bio()
  - add sanity check on ei.len in __update_extent_tree_range()
  - fix infinite loop in __insert_extent_tree()
  - fix zero-sized extent for precache extents
  - fix to mitigate overhead of f2fs_zero_post_eof_page()
  - fix to avoid migrating empty section
  - fix to truncate first page in error path of f2fs_truncate()
  - fix to update map->m_next_extent correctly in f2fs_map_blocks()
  - fix wrong layout information on 16KB page
  - fix to do sanity check on node footer for non inode dnode
  - fix to avoid NULL pointer dereference in f2fs_check_quota_consistency()
  - fix to detect potential corrupted nid in free_nid_list
  - fix to clear unusable_cap for checkpoint=enable
  - fix to zero data after EOF for compressed file correctly
  - fix to avoid overflow while left shift operation
  - fix condition in __allow_reserved_blocks()

f0712c2038 Description for this pull request:
- Add support for FS_IOC_{GET,SET}FSLABEL ioctl.
  - Two small clean-up patches.
  - Optimizes allocation bitmap loading time on large partitions
    with small cluster sizes.
  - Allow changes for discard, zero_size_dir, and errors options
    via remount.
  - Validate that the clusters used for the allocation bitmap are
    correctly marked as in-use during mount, preventing potential
    data corruption from reallocating the bitmap's own space.
  - Uses ratelimit to avoid too many error prints on I/O error path.
