Will Deacon e35123d83e arm64: lto: Strengthen READ_ONCE() to acquire when CONFIG_LTO=y ... When building with LTO, there is an increased risk of the compiler converting an address dependency headed by a READ_ONCE() invocation into a control dependency and consequently allowing for harmful reordering by the CPU. Ensure that such transformations are harmless by overriding the generic READ_ONCE() definition with one that provides acquire semantics when building with LTO.
