I agree that we should define dump_stack.o as obj-y. Also it makes
sense to move it to kernel/printk/. As Sergey said: it depends on
CONFIG_PRINTK and is in printk.h.

Steven, do you agree or would you suggest another location?
It was you who suggested to move the several functions from printk.c
to dump_stack.c. IMHO, the motivation was to fix responsibilities
(maintainer-ship) of this stuff. This will not really happen if
we move the file to printk directory.
