cc7bcbb5ad mmc: omap: add WQ_PERCPU to alloc_workqueue users
Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.

alloc_workqueue() treats all queues as per-CPU by default, while unbound
workqueues must opt-in via WQ_UNBOUND.

This default is suboptimal: most workloads benefit from unbound queues,
allowing the scheduler to place worker threads where they’re needed and
reducing noise when CPUs are isolated.

This continues the effort to refactor workqueue APIs, which began with
the introduction of new workqueues and a new alloc_workqueue flag in:

commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")

This change adds a new WQ_PERCPU flag to explicitly request
alloc_workqueue() to be per-cpu when WQ_UNBOUND has not been specified.

With the introduction of the WQ_PERCPU flag (equivalent to !WQ_UNBOUND),
any alloc_workqueue() caller that doesn’t explicitly specify WQ_UNBOUND
must now use WQ_PERCPU.

Once migration is complete, WQ_UNBOUND can be removed and unbound will
become the implicit default.

070f0336d1 mmc: mtk-sd: replace use of system_wq with system_percpu_wq
Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to

This patch continues the effort to refactor worqueue APIs, which has begun
with the change introducing new workqueues and a new alloc_workqueue flag:

commit 128ea9f6cc ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566 ("workqueue: Add new WQ_PERCPU flag")

Replace system_wq with system_percpu_wq, keeping the same old behavior.
The old wq (system_wq) will be kept for a few release cycles.

fda1e0af7c mmc: sdhci-of-dwcmshc: Add command queue support for rockchip SOCs
This adds CQE support for the Rockchip RK3588 and RK3576 platform. To
be functional, the eMMC device-tree node must have a 'supports-cqe;'
flag property.

As the RK3576 device-tree has been upstreamed with the 'supports-cqe;'
property set by default, the kernel already tried to use CQE, which
results in system hang during suspend. This fixes the issue.

9e80562521 mmc: pxamci: Simplify pxamci_probe() error handling using devm APIs
This patch refactors pxamci_probe() to use devm-managed resource
allocation (e.g. devm_dma_request_chan) and dev_err_probe() for
improved readability and automatic cleanup on probe failure.

It also removes redundant NULL assignments and manual resource release
logic from pxamci_probe(), and eliminates the corresponding release
calls from pxamci_remove().

1c64efcb08 Rust 'rustfmt' cleanup
'rustfmt', by default, formats imports in a way that is prone to
 conflicts while merging and rebasing, since in some cases it condenses
 several items into the same line.
 
 Document in our guidelines that we will handle this for the moment with
 the trailing empty comment workaround and make the tree 'rustfmt'-clean
 again.

 "smb client fixes, security and smbdirect improvements, and some minor cleanup:

   - Important OOB DFS fix

   - Fix various potential tcon refcount leaks

   - smbdirect (RDMA) fixes (following up from test event a few weeks

      - Fixes to improve and simplify handling of memory lifetime of

      - Make sure we really wait to reach SMBDIRECT_SOCKET_DISCONNECTED

        enough to avoid ib_post_send() from failing under pressure

 - Pick the correct translation regime when doing a PTW on
   the back of a SEA
 
 - Prevent userspace from injecting an event into a vcpu that isn't
   initialised yet
 
 - Move timer save/restore to the sysreg handling code, fixing EL2 timer

 - Add FGT-based trapping of MDSCR_EL1 to reduce the overhead of debug
 
 - Fix trapping configuration when the host isn't GICv3
 
 - Improve the detection of HCR_EL2.E2H being RES1
 
 - Drop a spurious 'break' statement in the S1 PTW
 
 - Don't try to access SPE when owned by EL3
 
 Documentation updates:
 
 - Document the failure modes of event injection
 
 - Document that a GICv3 guest can be created on a GICv5 host
   with FEAT_GCIE_LEGACY
 
 Selftest improvements:
 
 - Add a selftest for the effective value of HCR_EL2.AMO
 
 - Address build warning in the timer selftest when building with clang
 
 - Teach irqfd selftests about non-x86 architectures
 
 - Add missing sysregs to the set_id_regs selftest
 
 - Fix vcpu allocation in the vgic_lpi_stress selftest
 
 - Correctly enable interrupts in the vgic_lpi_stress selftest
 
 x86:

   bug fixed by commit 3ccbf6f470 ("KVM: x86/mmu: Return -EAGAIN if userspace
   deletes/moves memslot during prefault")
 
 - Don't try to get PMU capabilities from perf when running a CPU with hybrid

 guest_memfd:
 
 - Rework KVM_CAP_GUEST_MEMFD_MMAP (newly introduced in 6.18) into a more
   generic KVM_CAP_GUEST_MEMFD_FLAGS
 
 - Add a guest_memfd INIT_SHARED flag and require userspace to explicitly set
   said flag to initialize memory as SHARED, irrespective of MMAP.  The
   behavior merged in 6.18 is that enabling mmap() implicitly initializes
   memory as SHARED, which would result in an ABI collision for x86 CoCo VMs
   as their memory is currently always initialized PRIVATE.
 
 - Allow mmap() on guest_memfd for x86 CoCo VMs, i.e. on VMs with private
   memory, to enable testing such setups, i.e. to hopefully flush out any
   other lurking ABI issues before 6.18 is officially released.
 
 - Add testcases to the guest_memfd selftest to cover guest_memfd without MMAP,
   and host userspace accesses to mmap()'d private memory.

dbfdaeb381 tpm_crb: Add idle support for the Arm FF-A start method
According to the CRB over FF-A specification [1], a TPM that implements
the ABI must comply with the TCG PTP specification. This requires support
for the Idle and Ready states.

This patch implements CRB control area requests for goIdle and
cmdReady on FF-A based TPMs.

The FF-A message used to notify the TPM of CRB updates includes a
locality parameter, which provides a hint to the TPM about which
locality modified the CRB.  This patch adds a locality parameter
to __crb_go_idle() and __crb_cmd_ready() to support this.

f406055cb1 arm64 fixes:
- Explicitly encode the XZR register if the value passed to
    write_sysreg_s() is 0. The GIC CDEOI instruction is encoded as a
    system register write with XZR as the source register. However, clang
    does not honour the "Z" register constraint, leading to incorrect
    code generation
 
  - Ensure the interrupts (DAIF.IF) are unmasked when completing
    single-step of a suspended breakpoint before calling
    exit_to_user_mode(). With pseudo-NMIs, interrupts are (additionally)
    masked at the PMR_EL1 register, handled by local_irq_*()

fe69107ec7 RISC-V updates for v6.18-rc2
Some RISC-V fixes for v6.18-rc2, including changes to:
 
 - Disable CFI with Rust for any platform other than x86 and ARM64
 
 - Keep task mm_cpumasks up-to-date to avoid triggering M-mode firmware
   warnings if the kernel tries to send an IPI to an offline CPU
 
 - Improve kprobe address validation performance and avoid desyncs
   (following x86)
 
 - Avoid duplicate device probes by avoiding DT hardware probing when
   ACPI is enabled in early boot
 
 - Use the correct set of dependencies for CONFIG_ARCH_HAS_ELF_CORE_EFLAGS,
   avoiding an allnoconfig warning
 
 - Fix a few other minor issues
