Subject: CONFIG_HOTPLUG_CPU on x86

I've heard folks say that hotplug cpu is very reliable. I'm assuming
that's in the context of the x86 architecture. If so, how come
CONFIG_HOTPLUG_CPU is still listed as EXPERIMENTAL in arch/x86/Kconfig?
Should this be changed for the x86 architecture?

config HOTPLUG_CPU
bool "Support for suspend on SMP and hot-pluggable CPUs (EXPERIMENTAL)"
depends on SMP && HOTPLUG && EXPERIMENTAL && !X86_VOYAGER

Yes, it's a bit bizarre that something needed for suspending almost any
current laptop is still marked as "experimental"..

Why don't use guys just submit a patch that removes EXPERIMENTAL thing.
