 ## List of known changes from [aarch-system-2014-10.tar.xz](http://www.gem5.org/dist/current/arm/aarch-system-2014-10.tar.xz)
 1. The aarch64 bootloader is newer ([info](https://gem5.googlesource.com/public/gem5/+/47326f54222af99d96ab57508449d1bb62d03842)).
 2. The DTB for the VExpress_EMM64 platform is newer ([info](https://github.com/gem5/linux-arm64-gem5/commit/24fd6238427aad5c212493efeb1)).
-3. Added DTBs and kernels for the VExpress_GEM5_V1\* platforms.
+3. Added DTBs and kernels (version 4.4) for the VExpress_GEM5_V1\* platforms.
 4. Updated the /sbin/m5 binary for the different disk images ([info](https://gem5.googlesource.com/public/gem5/+/d4c1600c4e3e4f380f5582f8bfba97fb466a18ce)).
 5. Kernel for VExpress_EMM is 3.14 (it used to be 3.13)
 6. Kernels for VExpress_EMM\* platforms are compiled with gcc 4.8.5 (it used to be 4.8.2)

 ## How to generate the files
-1. Just run the run.sh script on the cloned repository (use sudo if you did not let users run docker as non-root as indicated above). On a successful run (that may take more than an hour), the user will get the aarch-system-20170421.tar.xz file in the same directory.
