It is also not correct :( Now you can't log multiple arguments at all,
since putting the stack pointer into the KTR log means that we can't
correctly dump it later. The stack frame could have been overwritten
in the mean time, actually that's very likely.

That's why the original macros have been needed for. It can be safely
used only with one argument.
