From 0dabb9d9fa389ad809351ff3de2c898ae3a22bbf Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Tue, 23 May 2017 14:43:30 -0500 Subject: [PATCH] i965: use mmap64 for Android Simplify the handling of mmap for Android by using mmap64 instead. mmap64 may have not existed for Android when this was written, but it's been around since 2013.
