BackMerge tag 'v6.15-rc5' into drm-next
Linux 6.15-rc5, requested by tzimmerman for fixes required in drm-next.
Signed-off-by: Dave Airlie <airlied@redhat.com>
The drm_gem_shmem_test_get_pages_sgt() gets a scatter-gather table using
the drm_gem_shmem_get_sg_table() function and rightfully calls
sg_free_table() on it. However, it's also supposed to kfree() the
returned sg_table, but doesn't.
This leads to a memory leak, reported by kmemleak. Fix it by adding a
kunit action to kfree the sgt when the test ends.

Use refcount_t helper for vmap_use_count to make refcounting consistent
with pages_use_count and pages_pin_count that use refcount_t. This also
makes vmapping to benefit from the refcount_t's overflow checks.

Merge v6.11-rc5 into drm-next
amdgpu pr conconflicts due to patches cherry-picked to -fixes, I might
as well catch up with a backmerge and handle them all. Plus both misc
and intel maintainers asked for a backmerge anyway.

The test here creates an sg table, but never maps it, when
we get to drm_gem_shmem_free, the helper tries to unmap and this
causes warnings on some platforms and debug kernels.
This also sets a 64-bit dma mask, as I see an swiotlb warning if I
stick with the default 32-bit one.
