Subject: drm/i915/ttm: restore min_page_size behaviour
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

Git-commit: 13c2ceb6addb6b14468e09b75832c98909eed8e7
Patch-mainline: v5.15-rc1
References: jsc#SLE-22601
We now have bo->page_alignment which perfectly describes what we need if
we have min page size restrictions for lmem. We can also drop the flag
here, since this is the default behaviour for all objects.
v2(Thomas):
- bo->page_alignment is in page units
