Yes.

Yes. Here's the relevant part of the call tree:
setup_arch
acpi_numa_init
acpi_numa_arch_fixup
acpi_online_node_fixup (test available_cpus)
...
acpi_boot_init
acpi_table_parse_madt(..., acpi_parse_lsapic, ...)
acpi_parse_lsapic (increment available_cpus)
Note that we test available_cpus in acpi_online_node_fixup()
before we increment it in acpi_parse_lsapic(), so the inner
loop is never executed.
