From 02aaa54418071c4877ba0375f4102f97910a3d17 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1636/4131] drm/amdgpu: Use GFP_NOIO with reclaim-safe locks
Locks that are held in reclaim-fs context (in MMU notifiers invoked
under memory pressure) must not themselves cause memory reclaims
while held to prevent deadlocks. Use GFP_NOIO to ensure this.
