函数名称：Lay out the SHF_ALLOC sections in a way not dissimilar to how ldmight -- code, read-only data, read-write data, small data. Tallysizes, and place the offsets into sh_entsize fields: high bit means itbelongs in init.

函数原型：static void layout_sections(struct module *mod, struct load_info *info)

返回类型：void

参数：
