Hi all,

After merging the etnaviv tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/gpu/drm/i915/gem/i915_gem_ttm.c: In function 'vm_fault_ttm':
drivers/gpu/drm/i915/gem/i915_gem_ttm.c:862:9: error: too many arguments to function 'ttm_bo_vm_fault_reserved'
  862 |   ret = ttm_bo_vm_fault_reserved(vmf, vmf->vma->vm_page_prot,
      |         ^~~~~~~~~~~~~~~~~~~~~~~~
In file included from include/drm/ttm/ttm_bo_driver.h:42,
                 from drivers/gpu/drm/i915/gem/i915_gem_ttm.c:6:

Caused by commit

  ebd4a8ec7799 ("drm/i915/ttm: move shrinker management into adjust_lru")

interacting with commit

  0d979509539e ("drm/ttm: remove ttm_bo_vm_insert_huge()")

from Linus' tree.

I applied the following merge fix patch.
