It's been removed indeed, but the value has been replaced by using
a MemoryRegionSection instead.  I understand current code is wrong
when DEBUG_TLB is #defined, but I think it is also wrong to just
remove this value in printf.  The question is whenever this debugging
is useful now, and whenever this now-missing value is interesting
for that and should be provided by other means.  Maybe we may just
remove whole thing here and everywhere.

Cc'ing authors.

While this patch looks really trivial, it is something which is of
use by the subsystem maintainer(s) at their disposal.

Thanks,

I interpret it as logging the function arguments, so dropping it sounded
like the right solution to me. Would be nice to turn it into a
tracepoint or at least some DPRINTF() macro that gets compile-tested.

Thanks, applied to the trivial patches queue.
