Using my favorite .config file, it happens that all the hotplug
options are off and the kernel doesn't build.

  LD      .tmp_vmlinux1
arch/ia64/kernel/built-in.o(.text+0x712): In function `acpi_unregister_ioapic':
: undefined reference to `iosapic_remove'
make: *** [.tmp_vmlinux1] Error 1

grep HOT .config
# CONFIG_HOTPLUG is not set
# CONFIG_HOTPLUG_CPU is not set
# CONFIG_HOTPLUG_PCI is not set
