[    9.770887] Kernel panic - not syncing: Fatal exception

Bisect reveals the problem was introduced in next-20200217 by following commit 

commit a75056fc1e7c 
mm/memcontrol.c: allocate shrinker_map on appropriate NUMA node

I can boot the kernel successfully if the patch is reverted. 

Boot log attached.

Thanks
