From 254ba022a91b2f6cf90b8f8aed91f4a8a3891a39 Mon Sep 17 00:00:00 2001
From: Chaudhary Amit Kumar <chaudharyamit.kumar@amd.com>
Date: Wed, 9 Jan 2019 21:01:21 +0530
Subject: [PATCH 5157/5725] drm/amdgpu: Use kvmalloc for allocating UVD/VCE/VCN
BO backup memory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The allocated size can be (at least?) as large as megabytes, and
there's no need for it to be physically contiguous.
May avoid spurious failures to initialize / suspend the corresponding
block while there's memory pressure.
