drm/amdgpu: Fix multi-level page table bugs for large BOs v3
Fix the start/end address calculation for address ranges that span multiple page directories in amdgpu_vm_alloc_levels. Add error messages if page tables aren't found. Otherwise the page table update would just fail silently. v2: * Change WARN_ON to WARN_ON_ONCE * Move masking of high address bits to caller * Add range-check for "from" and "to" v3: * Replace WARN_ON_ONCE in get_pt with pr_err in caller Signed-off-by: Felix Kuehling <Felix.Kuehling@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
