Macro mem_assign_absolute() is used to initialize a target CPU lowcore callback parameters. But despite the macro name it writes to the absolute lowcore only if the target CPU is offline. In case the CPU is online the macro does implicitly write to the normal memory. That behaviour is correct, but extremely subtle. Sacrifice few program bits in favour of clarity and distinguish between online vs offline CPUs and normal vs absolute lowcore pointer.
