This broke when compiling on i386 without X86_LOCAL_APIC because then
arch/x86/include/asm/smp.h doesn't include asm/apic.h which in turn includes
linux/delay.h.

Oh, thanks. I will also look at better handling hotplug CPU just to make
Paul happy (probably just disable on hotplug as you'll need to restart
any testing then), though as he said, it's obvious one shouldn't be
removing CPUs at the same time as benchmarking.
Jon.
