Name: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.

Proto:static void layout_sections(struct module *mod, struct load_info *info)

Type:void

Parameter:
