Subject: [PATCH] kernel: Export mm_access
Date: Tue, 23 May 2017 16:17:29 -0400
Message-ID: <5a9607b4-d2ac-fc7b-e43b-1e73c2651071@amd.com>
Patch-mainline: Submitted, https://patchwork.kernel.org/patch/9744281/
References: bsc#1040550

Exporting mm_access, which is required for implementing accelerated
equivalents of process_vm_readv/process_vm_writev for GPU memory in KFD
(AMD's GPU compute driver). This allows us to apply all the same remote
process memory access policies.
