Humor me: don't start commit message bodies with "This patch" or
variations thereof, and don't repeat the subject.  Suggest:

QMP command query-cpu-max returns the maximum number of CPUs supported
by the currently running emulator instance, as defined in its
QEMUMachine struct.

What's a QMP/qmp utility?  Let's drop this sentence.  In the future,
feel free to put testing info below the "---" line.

Grammar nit: s/has been/is/.  Even better, avoid passive voice.

Hmm, I just rewrote most of your commit message, so why not rewrite all
of it:

    New QMP command query-cpu-max and HMP command cpu_max

    These commands return the maximum number of CPUs supported by the
    currently running emulator instance, as defined in its QEMUMachine
    struct.

Perhaps Luiz can fix up the commit message commit, if you don't mind.

Patch looks good.

Should query commands for machine properties multiply, we should
consider creating a single command returning all of them.  I'm not
asking you to do that now.
