config ADVANCED_OPTIONS
bool "Prompt for advanced kernel configuration options"
help
This option will enable prompting for a variety of advanced kernel
configuration options. These options can cause the kernel to not
work if they are set incorrectly, but can be used to optimize certain
aspects of kernel memory management.
Unless you know what you are doing, say N here.

help
This option allows you to set the maximum amount of memory which
will be used as "low memory", that is, memory which the kernel can
access directly, without having to set up a kernel virtual mapping.
This can be useful in optimizing the layout of kernel virtual
memory.

This option allows you to set the kernel virtual address at which
the kernel will map low memory (the kernel image will be linked at
this address). This can be useful in optimizing the virtual memory
layout of the system.

Kprobes allows you to trap at almost any kernel address and
execute a callback function. register_kprobe() establishes
a probepoint and specifies the callback. Kprobes is useful
for kernel debugging, non-intrusive instrumentation and testing.
If in doubt, say "N".
