[PATCH v5 00/25] MADVISE FOR XE

[Himal Prasad Ghimiray]

-v6
Rebase on gpuvm patches
Address review comments

-v5
Restore attributes to default after free from userspace
Add defragment worker to merge cpu mirror vma with default attributes
Avoid using VMA in uapi
address review comments

-v4:
fix atomic policies
fix attribute copy
address review comments

Provides a user API to assign attributes like pat_index, atomic
operation type, and preferred location for SVM ranges.
The Kernel Mode Driver (KMD) may split existing VMAs to cover input
ranges, assign user-provided attributes, and invalidate existing PTEs so
that the next page fault/prefetch can use the new attributes.

Boris Brezillon (2):
  drm/gpuvm: Pass map arguments through a struct
  drm/gpuvm: Kill drm_gpuva_init()
