- bool "Preemptible Kernel"
- help
- This option reduces the latency of the kernel when reacting to
- real-time or interactive events by allowing a low priority process to
- be preempted even if it is in kernel mode executing a system call.
- This allows applications to run more reliably even when the system is
- under load.

- Say N if you are unsure.

config IPL
bool "Builtin IPL record support"
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.
This can also be compiled as a module, which will be called
appldata_net_sum.o.
