Subject: drm/xe/vma: Move pat_index to vma attributes
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=11974fe8c7eac3ee3f35dfe6696f097284bd67eb;p=users%2Fhch%2Fmisc.git

drm/xe/vma: Move pat_index to vma attributes

The PAT index determines how PTEs are encoded and can be modified by
madvise. Therefore, it is now part of the vma attributes.
