[Xen-devel] A question about CONFIG_SMP

["Tian, Kevin" <kevin.tian@xxxxxxxxx>]

Just a curious question, does anyone still care xen/UP? If yes, current
xen-unstable.hg 
failed to build quickly after undef CONFIG_SMP since many structures
include types 
defined only when CONFIG_SMP is on.

Just realize this issue when cleanup some IA64 code recently, where
CONFIG_SMP is still unstable and thus UP only.

Is there any benefit to have xen/UP? Reducing image size is the
immediate answer in my head...

Thanks,
Kevin
