The function insn_get_addr_ref() is capable of handling only 64-bit addresses. A previous commit introduced a function to handle 32-bit addresses. Invoke these two functions from a third wrapper function that calls the appropriate routine based on the address size specified in the instruction structure (obtained by looking at the code segment default address size and the address override prefix, if present). While doing this, rename the original function insn_get_addr_ref() with the more appropriate name get_addr_ref_64(), ensure it is only used for 64-bit addresses. Also, since 64-bit addresses are not possible in 32-bit builds, provide a dummy function such case.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
