The motivation is that sysAlloc/Free() currently aren't safe to be called without a valid G, because arm's xadd64() uses locks that require a valid G. The solution here was proposed by Dmitry Vyukov: use xadduintptr() instead of xadd64(), until arm can support xadd64 on all of its architectures (not a trivial task for arm).

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
