ACPI: boot correctly with "nosmp" or "maxcpus=0"
In MPS mode, "nosmp" and "maxcpus=0" boot a UP kernel with IOAPIC disabled. However, in ACPI mode, these parameters didn't completely disable the IO APIC initialization code and boot failed. init/main.c: Disable the IO_APIC if "nosmp" or "maxcpus=0" undefine disable_ioapic_setup() when it doesn't apply. i386: delete ioapic_setup(), it was a duplicate of parse_noapic() delete undefinition of disable_ioapic_setup() x86_64: rename disable_ioapic_setup() to parse_noapic() to match i386 define disable_ioapic_setup() in header to match i386 http://bugzilla.kernel.org/show_bug.cgi?id=1641 Acked-by: Andi Kleen <ak@suse.de> Signed-off-by: Len Brown <len.brown@intel.com>
