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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
