Hi all, I removed the _DISABLE_MMU #define from g1MMUTracker.cpp since it seems to be unused. Bug: https://bugs.openjdk.java.net/browse/JDK-8149137 Webrev: http://cr.openjdk.java.net/~ehelin/leo/8149137/ Testing: - JPRT - Run `make run-test-hotspot_gc` with fastdebug locally on my Linux x86-64 machine Thanks, Leo
