This allows you to specify the maximum number of CPUs which this
kernel will support. The maximum supported value is 64 and the
can be controlled through /sys/devices/system/cpu/cpu#.
Say N if you want to disable CPU hotplug.

- 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.

- Kprobes allows you to trap at almost any kernel address and

- for kernel debugging, non-intrusive instrumentation and testing.
