From 295fa2503fddac51fff29e8870f750e9a878f747 Mon Sep 17 00:00:00 2001 From: Laura Abbott Date: Fri, 16 Mar 2012 15:33:39 -0700 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.
