Hi,
In [*] I posted preliminary steps to unify hmp_info_tlb()
and hmp_info_mem() after making them per-CPU handler,
rather than target-specific method (which break single
binary). Since there is no rush and we need to figure
the usefulness of 'info tlb/mem' and what we want to do
with it, I dropped the series but salvaged these cleanup
patches.
Regards,
Phil.

hmp_info_tlb() is specific to tcg/system, move it to
target/i386/tcg/sysemu/hmp-cmds.c, along with the functions
it depend on (except addr_canonical() which is exposed in
"cpu.h").

The MMU/MPU are replaceable configuration blocks in the xtensa
architecture, their internals don't have architecture-wide significance
and I believe their exposure should be kept to a minimum.
I have a half-done xtensa MMU rework which I'd like to complete,
it only exposes the interface for address translation, opcode translation
and dumping.

Maybe because monitor_puts also seems to have a flush so that separate
call would do an additional flush to make sure the previously printed
lines are displayed? But I have no idea just guessing.

Why? Here's my attempt at an answer: because this runs only within HMP
command "info tlb". Using qemu_printf() there isn't wrong, but with
monitor_printf(), it's obvious that we print to the monitor.
On monitor_printf() vs. monitor_puts().
qemu_printf() behaves like monitor_printf() when monitor_cur() returns
non-null, which it certainly does within a monitor command.
monitor_printf() prints like monitor_puts() when monitor_is_qmp()
returns false, which it certainly does within an HMP command.
Note: despite their names, monitor_printf() and monitor_puts() are at
different interface layers!
We need a low-level function to send to a monitor, be it HMP or QMP:
monitor_puts().
We need a high-level function to format JSON and send it to QMP:
qmp_send_response().
We need a high-level functions to format text and send it to HMP:
monitor_printf(), ...
Naming the functions that expect an HMP monitor hmp_FOO() would make
more sense. Renaming them now would be quite some churn, though.
Discussed at
<https://lore.kernel.org/qemu-devel/87y1adm0os.fsf@pond.sub.org/>.
HMP code using both two layers to print gives me a slightly queasy
feeling. It's not wrong, though.

Not wrong, but I'd stick to monitor_printf() to keep the transformation
as simple as possible, and to sidestep the need for explaining the
subtleties around monitor_printf() vs. monitor_puts() in the commit

In addition to replacing qemu_printf(), the patch passes the current
monitor around. The alternative is monitor_cur(). I guess you pass
because you consider it cleaner and/or simpler. No objection, but I
suggest to mention it the commit message.
The patch is not wrong, so

You add a parameter below. I don't think this compiles :)

The hmp_ prefix is more cryptic than monitor_. Without knowing QEMU too
much I can guess what monitor_ does but would have to look up what
hmp_means so keeping monitor_ is better IMO. The solution to the naming
issue mentioned above may be renaming monitor_puts to something that tells
it's a low level function (and add a momitor_puts that behaves as
expected) but I can't come up with a name either. Maybe the low level
function could be called hmp_putt? Or add a comment near monitor_puts to
explain this for now.

It does compile, because this is dead code (guarded
by undefined DEBUG_MMU). Good example that dead code
tends to bitrot, thanks for noticing.
