This STDOUT vs _log() choice is a bit irregular, and I think you might
be better off abandoning it completely. Richard, Alex, do we really
need to optionally route printfery to log or stderr? (considering _log
is NOW stderr by default now, and -D option gives you some flexibility
there). Can we have just log and drop STDOUT mode?

Regards,
Peter

Style - you are replacing aligned \ continuation with one-space \
continuation.  I don't know if we have a distinct preference, but it's
probably better to leave the style unchanged if checkpatch.pl doesn't
complain about either way.

As that's minor,

QEMU_DPRINTF outputs to stderr, and, as you say qemu_log does it too.
Should QEMU_DPRINTF be removed and leave only qemu_log?

Yes, I think that all debug output like this should go via qemu_log.

Ahh I see now, you want to use the common factored-out code in P1
which is stderr specific. Perhaps that should use qemu_log. One option
would be to create a variant of it in common code that does uses
qemu_log instead of stderr and use that variant here. That way you can
preserve existing behaviour (and maintainer expectations), as much as
possible.

I think it's safe to assume that all TCG code wants to use qemu_log.
