[Intel-gfx] [PATCH v8 0/2] drm/i915: use pat_index instead of cache_level

[fei.yang@intel.com]

From: Fei Yang <fei.yang@intel.com>

This patch set was posted at
https://patchwork.freedesktop.org/series/116868/
Change title since the PTE patch was merged separately.

These patches are extracted from series
https://patchwork.freedesktop.org/series/115980/

This series refactor the cache policy programming so that the PTE
encode functions can be unified across all GEN12 platforms. This
refactor is also important in implementing the design which allows
uerspace to directly set cache policy for each Buffer Object.

v2: drop one patch that was merged separately
    341ad0e8e254 drm/i915/mtl: Add PTE encode function
v3: disable {get, set}_caching ioctl
v4: fix missing unlock introduced in v3, and
    solve a rebase conflict
v5: replace obj->cache_level with pat_set_by_user,
    fix i915_cache_level_str() for legacy platforms.
v6: squash the pte_encode patch because separating them causes
    bisect probelm. Also addressing some review comments from
    Tvrtko and Matt.
v7: fix checkpatch errors and warnings.
v8: BUILD_BUG_ON instead of WARN_ON_ONCE. Some updates in
    comments.
