From 7b903e44c40fdd8300582b0791ef20b70d81178c Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Fri, 13 Dec 2013 14:23:49 -0800 Subject: [PATCH] gpu: ion: Map only the vma size given When mapping carveout buffers into userspace, only map the size of the vma given, not the full size of the buffer since clients may map less than the buffer size.
