2023-12-12iommu/tegra: Use tegra_dev_iommu_get_stream_id() in the remaining placesJason Gunthorpe
This API was defined to formalize the access to internal iommu details on some Tegra SOCs, but a few callers got missed. Add them. The helper already masks by 0xFFFF so remove this code from the callers.

2023-11-30nouveau/tu102: flush all pdbs on vmm flushDave Airlie
This is a hack around a bug exposed with the GSP code, I'm not sure what is happening exactly, but it appears some of our flushes don't result in proper tlb invalidation for out BAR2 and we get a BAR2 fault from GSP and it all dies.

2023-11-29nouveau/gsp: replace zero-length array with flex-array member and use ↵Gustavo A. R. Silva
__counted_by Fake flexible arrays (zero-length and one-element arrays) are deprecated, and should be replaced by flexible-array members. So, replace zero-length array with a flexible-array member in `struct PACKED_REGISTRY_TABLE`. Also annotate array `entries` with `__counted_by()` to prepare for the coming implementation by GCC and Clang of the `__counted_by` attribute. Flexible array members annotated with `__counted_by` can have their accesses bounds-checked at run-time via `CONFIG_UBSAN_BOUNDS` (for array indexing) and `CONFIG_FORTIFY_SOURCE` (for strcpy/memcpy-family functions). This fixes multiple -Warray-bounds warnings: drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1069:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1070:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1071:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:1072:29: warning: array subscript 0 is outside array bounds of 'PACKED_REGISTRY_ENTRY[0]' [-Warray-bounds=] While there, also make use of the struct_size() helper, and address checkpatch.pl warning: WARNING: please, no spaces at the start of a line This results in no differences in binary output.
