module: include other structures in module version check
With CONFIG_MODVERSIONS, we version 'struct module' using a dummy export, but other things matter too: 1) 'struct modversion_info' determines the layout of the __versions section, 2) 'struct kernel_param' determines the layout of the __params section, 3) 'struct kernel_symbol' determines __ksymtab*. 4) 'struct marker' determines __markers. 5) 'struct tracepoint' determines __tracepoints. So we rename 'struct_module' to 'module_layout' and include these in the signature. Now it's general we can add others later on without confusion. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
