format modules, which are currently only used on the amd64 platform. This initial implementation just parses enough of the module to allow it to extract dependencies and load all the bits into the right place in memory, so the kernel must still do the full relocation and linking. The details of the loaded sections are passed to the kernel by supplying a copy of the ELF section header table as module metadata with the MODINFOMD_SHDR tag.
