cf856ca9b9 drm/amdgpu: Update vm start, end, hole to support 57bit address
Change gmc macro AMDGPU_GMC_HOLE_START/END/MASK to 57bit if vm root
level is PDB3 for 5-level page tables.

The macro access adev without passing adev as parameter is to minimize
the code change to support 57bit, then we have to add adev variable in
several places to use the macro.

Because adev definition is not available in all amdgpu c files which
include amdgpu_gmc.h, change inline function amdgpu_gmc_sign_extend to
macro.

f6b1c1f5fd drm/amdgpu: GPU vm support 5-level page table
If GPU supports 5-level page table, but CPU disable 5-level page table
by using boot option no5lvl or CPU feature not available, the virtual
address will be 48bit, not needed to enable 5-level page table on GPU
vm.

If adev->vm_manager.num_level, number of pde levels, set to 4, then
gfxhub and mmhub register VM_CONTEXTx_CNTL/PAGE_TABLE_DEPTH will set
to 4 to enable 5-level page table in page table walker.

Set vm_manager.root_level to AMDGPU_VM_PDE3, then update GPU mapping
will allocate and update PDE3/PDE2/PDE1/PDE0/PTB 5-level page tables.

If max_level is not 4, no change for the logic to support features
needed by old ASICs.

65db7a1f9c drm/i915/color: Add 3D LUT to color pipeline
Add helpers to program the 3D LUT registers and arm them.

LUT_3D_READY in LUT_3D_CLT is cleared off by the HW once
the LUT buffer is loaded into it's internal working RAM.
So by the time we try to load/commit new values, we expect
it to be cleared off. If not, log an error and return
without writing new values. Do it only when writing with MMIO.
There is no way to read register within DSB execution.

v2:
- Add information regarding LUT_3D_READY to commit message (Jani)
- Log error instead of a drm_warn and return without committing changes
  if 3DLUT HW is not ready to accept new values.
- Refactor intel_color_crtc_has_3dlut()
  Also remove Gen10 check (Suraj)
v3:
- Addressed review comments (Suraj)
