[CIR] Split CIR_UnaryOp into individual operations
Split the monolithic cir.unary operation (which dispatched on a
UnaryOpKind enum) into four separate operations: cir.inc, cir.dec,
cir.minus, and cir.not.
This follows the same pattern used when cir.binop was split into
individual binary operations (AddOp, SubOp, etc.).
Changes:
- Add CIR_UnaryOpInterface with getInput()/getResult() methods
- Add CIR_UnaryOp and CIR_UnaryOpWithOverflowFlag base classes
- Define IncOp, DecOp, MinusOp, NotOp with per-op folds
- Add Involution trait to NotOp for not(not(x)) -> x folding
- Replace createUnaryOp() with createInc/Dec/Minus/Not builders
- Split LLVM lowering into four separate patterns
- Split LoweringPrepare complex-type handling per unary op
- Update CIRCanonicalize and CIRSimplify for new op types
- Update all codegen files to use bool params instead of UnaryOpKind

Clean-up / consolidation of m68k bus error / address error handling
code. This is not a very radical change for most m68k platforms,
since they were using a version of this re-factored code already via
an #include directive in locore.s. Now, however, the bus error handlers
are split into CPU "generation"-specific files, and brought into the
kernel via the CPU options in the kernel config file (the goal being
to reduce boilerplate in each locore.s).
The more notable changes:
- amiga and atari no longer have their own copy of each handler, and
some of their local tweaks have been folded into the shared code.
- sun2's bus error handling code has been re-factored into a shared
buserr_10.s to facilitate support for other 68010-based systems (all
of which have their own custom MMU).
- sun3's bus error handling code has been re-refactored into the
shared buserr_2030.s. The Sun3-specific MMU handling is treated
just like the HP-specific MMU handling that was already there.
This additional #ifdef is a small price to pay for more code sharing.
- sun3x now also uses the shared buserr_2030.s rather than an identical

Import gdb-17.1, previous was 16.3
This version of GDB includes the following changes and enhancements:
* x86-64 CET shadow stack support
* Debugging Linux programs that use AArch64 Guarded Control Stacks
* GDB record feature now supports rv64gc architectures
* 'info threads' command support for two new options '-stopped' and
'-running' to limit the list of displayed threads.
* On Linux and FreeBSD, the addresses shown by the 'info
sharedlibrary' command are now for the full memory range
allocated to the shared library.
* Linux checkpoints now work with multiple inferiors
* Improved linker namespace support
* Warnings and error messages now start with an emoji (warning
sign, or cross mark) if supported by the host charset.
Configurable.
* Built-in support for TLS on Linux as backup when libthread_db is
not available. Supported on the x86_64, aarch64, ppc64, s390x,

[IR] Implement successors as Use iterators (#186616)
This is possible since now all successor operands are stored
consecutively.
There is just one out-of-line function call instead of one call to
getSuccessor() per operand.
[X86] isSplatValueForTargetNode - test source value for vector uniform shift ops (#186619)
For old SSE style vector shifts, we just need to check the shifted value is a splat as the shift amount is uniform

libpciaccess: update to 0.19.
This release adds a new pci_device_is_boot_display() API, with support
currently implemented only for Linux systems using sysfs.
It also adds a -Dinstall-scanpci option to the meson configuration for
those who want to install this version of scanpci.
In addition, it corrects build issues on FreeBSD 15 and DragonFly, and
fixes a long-standing bug if there were multiple users of libpciaccess
in the same process and one called pci_system_cleanup before the others
were done using pciaccess.
[CIR] Remove cir.unary(plus, ...) and emit nothing for unary plus (#185278)
Traditional codegen never emits any operation for unary plus — it just
visits the subexpression as a pure identity at the codegen level. Align
CIRGen with this behavior by removing Plus from UnaryOpKind entirely
and having VisitUnaryPlus directly visit the subexpression with the
appropriate promotion/demotion handling.
Fix mock infrastructure to coerce dict results to Pydantic models for generic services
This commit fixes an issue where the mock infrastructure (test.set_mock)
returns plain dicts for methods that internally return Pydantic models.
Generic services (those with Config.generic = True) like DockerService
return Pydantic model instances from their standard CRUD/Config methods
(e.g. docker.config returns a DockerEntry). When internal callers use
attribute access (e.g. .pool) on the result, mocks returning plain dicts
would fail with "'dict' object has no attribute 'pool'".
The fix detects at mock registration time whether the mocked method
belongs to a generic service and returns a model matching Config.entry.
If so, the mock's dict results are automatically wrapped via
model_construct() before being returned to callers. Non-generic services,
primitive-returning methods, and custom methods with non-entry return
types are unaffected.
Merge tag 'rust-fixes-7.0-2' of git://git.kernel.org/pub/scm/linux/kernel/git/ojeda/linux
Pull Rust fixes from Miguel Ojeda:
"Toolchain and infrastructure:
- Remap paths to avoid absolute ones starting with the upcoming Rust
1.95.0 release. This improves build reproducibility, avoids leaking
the exact path and avoids having the same path appear in two forms
The approach here avoids remapping debug information as well, in
order to avoid breaking tools that used the paths to access source
files, which was the previous attempt that needed to be reverted
- Allow 'unused_features' lint for the upcoming Rust 1.96.0 release.
While well-intentioned, we do not benefit much from the new lint
- Emit dependency information into '$(depfile)' directly to avoid a
temporary '.d' file (it was an old approach)
