 "The majority of changes here are small device-specific fixes for ASoC

  The only significant high LOC is found in the Cirrus firmware driver,

  they look fine for taking as a last minute fix, too"

31000732d5 iommu/vt-d: Fix identity map bounds in si_domain_init()
Intel IOMMU operates on inclusive bounds (both generally aas well as
iommu_domain_identity_map()). Meanwhile, for_each_mem_pfn_range() uses
exclusive bounds for end_pfn. This creates an off-by-one error when
switching between the two.

6e01b7601d KVM: x86: Implement kvm_arch_vcpu_pre_fault_memory()
Wire KVM_PRE_FAULT_MEMORY ioctl to kvm_mmu_do_page_fault() to populate guest
memory.  It can be called right after KVM_CREATE_VCPU creates a vCPU,
since at that point kvm_mmu_create() and kvm_init_mmu() are called and
the vCPU is ready to invoke the KVM page fault handler.

The helper function kvm_tdp_map_page() takes care of the logic to
process RET_PF_* return values and convert them to success or errno.

9aed7a6c0b KVM: Document KVM_PRE_FAULT_MEMORY ioctl
Adds documentation of KVM_PRE_FAULT_MEMORY ioctl. [1]

It populates guest memory.  It doesn't do extra operations on the
underlying technology-specific initialization [2].  For example,
CoCo-related operations won't be performed.  Concretely for TDX, this API
won't invoke TDH.MEM.PAGE.ADD() or TDH.MR.EXTEND().  Vendor-specific APIs
are required for such operations.

The key point is to adapt of vcpu ioctl instead of VM ioctl.  First,
populating guest memory requires vcpu.  If it is VM ioctl, we need to pick
one vcpu somehow.  Secondly, vcpu ioctl allows each vcpu to invoke this
ioctl in parallel.  It helps to scale regarding guest memory size, e.g.,
hundreds of GB.

27e6a24a4c mm, virt: merge AS_UNMOVABLE and AS_INACCESSIBLE
The flags AS_UNMOVABLE and AS_INACCESSIBLE were both added just for guest_memfd;
AS_UNMOVABLE is already in existing versions of Linux, while AS_INACCESSIBLE was
acked for inclusion in 6.11.

But really, they are the same thing: only guest_memfd uses them, at least for
now, and guest_memfd pages are unmovable because they should not be
accessed by the CPU.

So merge them into one; use the AS_INACCESSIBLE name which is more comprehensive.
At the same time, this fixes an embarrassing bug where AS_INACCESSIBLE was used
as a bit mask, despite it being just a bit index.

The bug was mostly benign, because AS_INACCESSIBLE's bit representation (1010)
corresponded to setting AS_UNEVICTABLE (which is already set) and AS_ENOSPC
(except no async writes can happen on the guest_memfd).  So the AS_INACCESSIBLE
flag simply had no effect.

Fixes: 1d23040caa ("KVM: guest_memfd: Use AS_INACCESSIBLE when creating guest_memfd inode")
Fixes: c72ceafbd1 ("mm: Introduce AS_INACCESSIBLE for encrypted/confidential memory")

Combined with CONFIG_WERROR=y these can halt the build.

The fix (annotating the structure field with __printf())

db19d3aa77 clocksource/drivers/sh_cmt: Address race condition for clock events
There is a race condition in the CMT interrupt handler. In the interrupt
handler the driver sets a driver private flag, FLAG_IRQCONTEXT. This
flag is used to indicate any call to set_next_event() should not be
directly propagated to the device, but instead cached. This is done as
the interrupt handler itself reprograms the device when needed before it
completes and this avoids this operation to take place twice.

It is unclear why this design was chosen, my suspicion is to allow the
struct clock_event_device.event_handler callback, which is called while
the FLAG_IRQCONTEXT is set, can update the next event without having to
write to the device twice.

Unfortunately there is a race between when the FLAG_IRQCONTEXT flag is
set and later cleared where the interrupt handler have already started to
write the next event to the device. If set_next_event() is called in
this window the value is only cached in the driver but not written. This
leads to the board to misbehave, or worse lockup and produce a splat.

The design have been part of the driver since it was first merged in
early 2009. It becomes increasingly harder to trigger the issue the
older kernel version one tries. It only takes a few boots on v6.10-rc5,
while hundreds of boots are needed to trigger it on v5.10.

Close the race condition by using the CMT channel lock for the two
competing sections. The channel lock was added to the driver after its
initial design.

3669716401 thermal: core: Add sanity checks for polling_delay and passive_delay
If polling_delay is nonzero and passive_delay is greater than
polling_delay, the thermal zone temperature will be updated less
often when tz->passive is nonzero, which is not as expected.  Make
the thermal zone registration fail with -EINVAL in that case as
this is a clear thermal zone configuration mistake.

If polling_delay is nonzero and passive_delay is 0, which is regarded
as a valid thermal zone configuration, the thermal zone will use polling
except when tz->passive is nonzero.  However, the expected behavior in
that case is to continue temperature polling with the same delay value
regardless of tz->passive, so set passive_delay to the polling_delay
value then.

0728c81087 thermal: trip: Pass trip pointer to .set_trip_temp() thermal zone callback
Out of several drivers implementing the .set_trip_temp() thermal zone
operation, three don't actually use the trip ID argument passed to it,
two call __thermal_zone_get_trip() to get a struct thermal_trip
corresponding to the given trip ID, and the other use the trip ID as an
index into their own data structures with the assumption that it will
always match the ordering of entries in the trips table passed to the
core during thermal zone registration, which is fragile and not really
guaranteed.

Even though the trip IDs used by the core are in fact their indices in the
trips table passed to it by the thermal zone creator, that is purely a
matter of convenience and should not be relied on for correctness.

For this reason, modify trip_point_temp_store() to pass a (const) trip
pointer to .set_trip_temp() and adjust the drivers implementing it
accordingly.

This helps to simplify the drivers invoking __thermal_zone_get_trip()
from their .set_trip_temp() callback functions because they will not
need to do it now and the other drivers can store their internal
trip indices in the priv field in struct thermal_trip and their
.set_trip_temp() callback functions can get those indices from there.

The intel_quark_dts thermal driver can instead use the trip type to
determine the requisite trip index.

If we encounter an error on i2c packet transmit, we won't have a valid
flow anymore; since we didn't transmit a valid packet sequence, we'll
have to wait for the key to timeout instead of dropping it on the reply.

This causes the i2c lock to be held for longer than necessary.

Instead, invalidate the flow on TX error, and release the i2c lock
immediately.
