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).
