Summary
Go 1.19 introduced types like atomic.Uint64, atomic.Int32, atomic.Bool, that provide automatic alignment for 32-bit platforms, plus extra safety to ensure access to the underlying value only uses atomic methods. This converts nearly all the calls to atomic to use these types. It also catches a few places where non-atomic and atomic access were mixed together.
