Well, I told you I'd write some Kconfig magic for you, but I can't since
I can't apply these patches. :)

You need this in a Kconfig file somewhere:

config CHECKPOINT_RESTART
	prompt "Good prompt"
	def_bool y
	depends on X86_32 && EXPERIMENTAL
	help
		Lots of fun help...

config SELECT_ALL_NAMESPACES
	prompt "Enable all kernel namespace support"
	selects IPC_NS NET_NS ...
	help
		This option will save you having to go track down
		all of the individual places that namespaces are
		supported in the kernel.

		If you don't turn this on, the restart porttion
		of checkpoint/restart gets a lots less reliable...	

probably in checkpoint/Kconfig.

Then, in all of the architectures' arch/*/Kconfig files, you need to:

source "checkpoint/Kconfig"

Then, the Makefile looks like this:

--- /dev/null   2008-04-22 10:49:52.000000000 -0700
+++ oren-cr.git-dave/checkpoint/Makefile        2008-08-22 12:30:53.000000000 -0700

+obj-$(CONFIG_CHECKPOINT_RESTART) += sys.o checkpoint.o restart.o
