I will do so.  BTW,

config SOFTWARE_SUSPEND
	bool "Software Suspend (Hibernation)"
	depends on PM && SWAP && (((X86 || PPC64_SWSUSP) && (!SMP ||
			SUSPEND_SMP)) || ((FRV || PPC32) && !SMP))

and

config SUSPEND_SMP
	bool
	depends on HOTPLUG_CPU && (X86 || PPC64) && PM

So, no HOTPLUG_CPU -> no SOFTWARE_SUSPEND.  I don't expect a
single-processor, dual-core PC to require CPU hotplugging support.
