Is there a reason we couldn't just rename all of the existing per-arch
module_alloc() calls to be called, say, "arch_module_alloc()", then put
this new rlimit code in a generic helper that does:


	if (check_inc_mod_rlimit(size))
		return NULL;

	p = arch_module_alloc(...);

	...

	update_mod_rlimit(p, size);
