Everybody who wants to run Linux under VM != VM4.2 should select
this option.
-config SHARED_KERNEL
- bool "VM shared kernel support"
- depends on !JUMP_LABEL
- help
- Select this option, if you want to share the text segment of the
- Linux kernel between different VM guests. This reduces memory
- usage with lots of guests but greatly increases kernel size.
- Also if a kernel was IPL'ed from a shared segment the kexec system
- call will not work.
- You should only select this option if you know what you are
- doing and want to exploit this feature.

- Enable this option to add support for the old s390-virtio

- type of virtio devices is only available on the experimental

- 1.4 and uses it by default since version 2.4), you probably won't
