In a function definition they mean exactly the same thing (and > the kernel uses (void) everywhere else, which many people find clearer). And I think () functions expected a caller-provided parameter save area on powerpc64le, while (void) functions do not. It does not matter for an empty function, but GCC prefers to use the parameter save area instead of setting up a stack frame if it is present. So you get stack corruption if you call a () function as a (void) function. (The other way round is fine.)
