We silence btree errors in btree_node_scan, since it's probing and
errors are expected: add a fake pass so that btree_node_scan is no
longer recovery pass 0, and we don't think we're in btree node scan when
reading btree roots.

When we truncate a bset (due to it extending past the end of the btree
node), we can't skip the rest of the validation for e.g. the packed
format (if it's the first bset in the node).

When the Tx FIFO is empty and the last command has no STOP bit
set, the master holds SCL low. If I2C_DYNAMIC_TAR_UPDATE is not
set, BIT(13) MST_ON_HOLD of IC_RAW_INTR_STAT is not enabled,
causing the __i2c_dw_disable() timeout. This is quite similar to
commit 2409205acd3c ("i2c: designware: fix __i2c_dw_disable() in
case master is holding SCL low"). Also check BIT(7)
MST_HOLD_TX_FIFO_EMPTY in IC_STATUS, which is available when
IC_STAT_FOR_CLK_STRETCH is set.

Pull bcachefs fixes from Kent Overstreet:
"Some trivial syzbot fixes, two more serious btree fixes found by
looping single_devices.ktest small_nodes:
- Topology error on split after merge, where we accidentaly picked
the node being deleted for the pivot, resulting in an assertion pop
- New nodes being preallocated were left on the freedlist, unlocked,
resulting in them sometimes being accidentally freed: this dated
from pre-cycle detector, when we could leave them locked. This
should have resulted in more explosions and fireworks, but turned
out to be surprisingly hard to hit because the preallocated nodes
were being used right away.
The fix for this is bigger than we'd like - reworking btree list
handling was a bit invasive - but we've now got more assertions and
it's well tested.
- Also another mishandled transaction restart fix (in
btree_node_prefetch) - we're almost done with those"

Pull arm64 fixes from Will Deacon:
"Here is a (hopefully) final round of arm64 fixes for 6.12 that address
some user-visible floating point register corruption. Both of the
Marks have been working on this for a couple of weeks and we've ended
up in a position where SVE is solid but SME still has enough pending
issues that the most pragmatic solution for the release and stable
backports is to disable the feature. Yes, it's a shame, but the
hardware is rare as hen's teeth at the moment and we're better off
getting back to a known good state before fixing it all properly.
We're also improving the selftests for 6.13 to help avoid merging
broken code in the future.
Anyway, the good news is that we're removing a lot more code than
we're adding.
Summary:
- Fix handling of SVE traps from userspace on preemptible kernels
when converting the saved floating point state into SVE state.
- Remove broken support for the SMCCCv1.3 "SVE discard hint"
optimisation.
- Disable SME support, as the current support code suffers from
numerous issues around signal delivery, ptrace access and
context-switch which can lead to user-visible corruption of the
register state"

When flag_is_changeable_p() is unused, it prevents kernel builds
with clang, `make W=1` and CONFIG_WERROR=y:
arch/x86/kernel/cpu/common.c:351:19: error: unused function 'flag_is_changeable_p' [-Werror,-Wunused-function]
351 | static inline int flag_is_changeable_p(u32 flag)
| ^~~~~~~~~~~~~~~~~~~~
Fix this by moving core around to make sure flag_is_changeable_p() is
always being used.
See also commit 6863f5643dd7 ("kbuild: allow Clang to find unused static
inline functions for W=1 build").
While at it, fix the argument type to be unsigned long along with
the local variables, although it currently only runs in 32-bit cases.
Besides that, makes it return boolean instead of int. This induces
the change of the returning type of have_cpuid_p() to be boolean
as well.

[Why]
In the case where a dml allocation fails for any reason, the
current state's dml contexts would no longer be valid. Then
subsequent calls dc_state_copy_internal would shallow copy
invalid memory and if the new state was released, a double
free would occur.
[How]
Reset dml pointers in new_state to NULL and avoid invalid
pointer

Enable the cleaner shader for GFX11.0.0/11.0.2 GPUs to provide data
isolation between GPU workloads. The cleaner shader is responsible for
clearing the Local Data Store (LDS), Vector General Purpose Registers
(VGPRs), and Scalar General Purpose Registers (SGPRs), which helps
prevent data leakage and ensures accurate computation results.
This update extends cleaner shader support to GFX11.0.0/11.0.2 GPUs,
previously available for GFX11.0.3. It enhances security by clearing GPU
memory between processes and maintains a consistent GPU state across KGD
and KFD workloads.

The event buffer does not need to be allocated if something has failed in
setting up event irq's.
In prep for adjusting event configuration for DCD events move the buffer
allocation to the end of the event configuration.

The device DAX structure is being enhanced to track additional DCD
information. Specifically the range tuple needs additional parameters.
The current range tuple is not fully documented and is large enough to
warrant its own definition.
Separate the struct dax_dev_range definition and document it prior to
adding information for DC.

In some cases, the compiler may decide to emit DWARF FDE frames with
64-bit signed fields for the code offset and range fields. This may
happen when using the large code model, for instance, which permits
an executable to be spread out over more than 4 GiB of address space.
Whether this is the case can be inferred from the augmentation data in
the CIE frame, so decode this data before processing the FDE frames.

The dynamic SCS patching code pretends to parse the DWARF augmentation
data in the CIE (header) frame, and handle accordingly when processing
the individual FDE frames based on this CIE frame. However, the boolean
variable is defined inside the loop, and so the parsed value is ignored.
The same applies to the code alignment field, which is also read from
the header but then discarded.
This was never spotted before because Clang is the only compiler that
supports dynamic SCS patching (which is essentially an Android feature),
and the unwind tables it produces are highly uniform, and match the
de facto defaults.
So instead of testing for the 'z' flag in the augmentation data field,
require a fixed augmentation data string of 'zR', and simplify the rest
of the code accordingly.
Also introduce some error codes to specify why the patching failed, and
log it to the kernel console on failure when this happens when loading a
module. (Doing so for vmlinux is infeasible, as the patching is done
extremely early in the boot.)

Code to support CXL Dynamic Capacity devices will have extent ranges
which need to be compared for intersection not a subset as is being
checked in range_contains().
range_overlaps() is defined in btrfs with a different meaning from what
is required in the standard range code. Dan Williams pointed this out
in [1]. Adjust the btrfs call according to his suggestion there.
Then add a generic range_overlaps().

The profiling of single-thread selftests bench reveals a bottlenect in
caches_clean_inval_pou() on ARM64. On my local testing machine, this
function takes approximately 34% of CPU cycles for trig-uprobe-nop and
trig-uprobe-push.
This patch add a check to avoid unnecessary cache flush when writing
instruction to the xol slot. If the instruction is same with the
existing instruction in slot, there is no need to synchronize D/I cache.
Since xol slot allocation and updates occur on the hot path of uprobe
handling, The upstream kernel running on Kunpeng916 (Hi1616), 4 NUMA
nodes, 64 cores@ 2.4GHz reveals this optimization has obvious gain for
nop and push testcases.

In current logic, it calls ring_alloc followed by a ring_test. ring_test
in turn will call another ring_alloc. This is illegal usage as a
ring_alloc is expected to be closed properly with a ring_commit. Change
to commit the map/unmap queue packet first followed by a ring_test. Add a
comment about the usage of ring_test.
Also, reorder the current pre-condition checks of job hang or kiq ring
scheduler not ready. Without them being met, it is not useful to attempt
ring or memory allocations.
Fixes tag refers to the original patch which introduced this issue which
then got carried over into newer code.
