[MLIR] Add fusability query to TilingInterface (#166502)
This introduces `isOpFusableWithProducer/Consumer` methods to the
TilingInterface that enable querying whether a tilable op can be fused
into a given set of producer slices or consumer slice without generating
IR. This is needed to enable use of the tiling interface in pattern
rewrites, as without this any pattern rewrite that tries to invoke the
method to tile is allowed to generate IR and fail.

Merge tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd
Pull iommufd updates from Jason Gunthorpe:
"This is a pretty consequential cycle for iommufd, though this pull is
not too big. It is based on a shared branch with VFIO that introduces
VFIO_DEVICE_FEATURE_DMA_BUF a DMABUF exporter for VFIO device's MMIO
PCI BARs. This was a large multiple series journey over the last year
and a half.
Based on that work IOMMUFD gains support for VFIO DMABUF's in its
existing IOMMU_IOAS_MAP_FILE, which closes the last major gap to
support PCI peer to peer transfers within VMs.
In Joerg's iommu tree we have the "generic page table" work which aims
to consolidate all the duplicated page table code in every iommu
driver into a single algorithm. This will be used by iommufd to
implement unique page table operations to start adding new features
and improve performance.

- Support for new hardware revision in the hisi_acc vfio-pci variant
driver where the migration registers can now be accessed via the PF.
When enabled for this support, the full BAR can be exposed to the
user (Longfang Liu)
- Fix vfio cdev support for VF token passing, using the correct size
for the kernel structure, thereby actually allowing userspace to
provide a non-zero UUID token. Also set the match token callback for
the hisi_acc, fixing VF token support for this this vfio-pci variant

[libclc] Add OpenCL atomic_*_explicit builtins (#168318)
Implement atomic_*_explicit (e.g. atomic_store_explicit) with
memory_order plus optional memory_scope.
OpenCL memory_order maps 1:1 to Clang (e.g. OpenCL memory_order_relaxed
== Clang __ATOMIC_RELAXED), so we pass it unchanged to clc_atomic_*
function which forwards to Clang _scoped_atomic* builtins.
Other changes:
* Add __opencl_get_clang_memory_scope helper in opencl/utils.h (OpenCL
scope -> Clang scope).
* Correct atomic_compare_exchange return type to bool.
* Fix atomic_compare_exchange to return true when value stored in the
pointer equals expected value.
* Remove volatile from CLC functions so that volatile isn't present in
LLVM IR.
* Add '-fdeclare-opencl-builtins -finclude-default-header' flag to
include

- Introduction of the generic IO page-table framework with support for
Intel and AMD IOMMU formats from Jason.
This has good potential for unifying more IO page-table
implementations and making future enhancements more easy. But this
also needed quite some fixes during development. All known issues
have been fixed, but my feeling is that there is a higher potential
than usual that more might be needed.
- Intel VT-d updates:
- Use right invalidation hint in qi_desc_iotlb()
- Reduce the scope of INTEL_IOMMU_FLOPPY_WA
- ARM-SMMU updates:

Add a `breakpoint add` command to fix the option-madness that is `breakpoint set` (#156067)
Someone came up with a clever idea for a new breakpoint type, but we
couldn't figure out how to add it in an ergonomic way because
`breakpoint set` has used up all the short-option characters. And even
if they did find a way to add it, the help for `break set` is so
confusing - because of the way it is implemented - that very few people
would detect the addition.
The basic problem is that `break set` distinguishes amongst the
fundamental breakpoint types it offers by which "required option" you
provide. If you pass a `-a` you are setting an address breakpoint, if
`-n`, `-F`, etc. a symbol name based breakpoint. And so forth. That is
however pretty hard to discern from the option grouping printing from
`help break set`. `break set` also suffers from the problem that it uses
common options in different ways depending on which "required" option is
present, which makes documenting the various behaviors difficult. And as
we run out of single letters it makes extending it difficult to
impossible.
