From fdd5faaa08f891153ac4fd8cedace6d95bed0968 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Christian=20K=C3=B6nig?= Date: Sat, 4 Nov 2017 16:51:44 +0100 Subject: [PATCH] drm/amdgpu: cleanup vm_size handling MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It's pointless to have the same value twice, just always use max_pfn.
