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

Caused by commit
a1d2a6339961 ("drm/lima: driver for ARM Mali4xx GPUs")
interacting with commit
a3e4d3f97ec8 ("XArray: Redesign xa_alloc API")
from Linus' tree (v5.1-rc1).
I have applied the following patch for today. It could be applied as
part of a merge of v5.1-rc1 into drm-misc.
