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