I'll follow up with an update after enabling CONFIG_EARLY_PRINTK, but
to answer your other questions, my cfg file:

        [global]
        default=default

        [default]
        options=console=dtuart dtuart=serial0 conswitch=x
        kernel=ImageX console=hvc0 earlycon=pl011,0x7ff80000 rootwait
root=/dev/sda3
        dtb=junoX

I copied that from the link I referenced earlier, I believe.  The only
differences are that I differentiated my default kernel and dtb from
the Xen ones by calling the Xen kernel and dtb ImageX and junoX.  My
root device is indeed /dev/sda3.

Yes, my dom0 kernel boots all CPUs successfully.  I didn't really
exercise them, but I can see all six of them.
