 6 * insn_page is a special 4k aligned dummy function for kprobes.
 7 * It will contain all kprobed instructions that are out-of-line executed.
 8 * The page must be within the kernel image to guarantee that the
 9 * out-of-line instructions are within 2GB distance of their original
10 * location. Using a dummy function ensures that the insn_page is within
11 * the text section of the kernel and mapped read-only/executable from
12 * the beginning on, thus avoiding to split large mappings if the page
13 * would be in the data section instead.
