You won't find a function in kernel/module.c that looks like it has
the name "sys_init_module". Instead, the function is defined by using
a macro, and it looks like this:

/* This is where the real work happens */
SYSCALL_DEFINE3(init_module, void __user *, umod,
unsigned long, len, const char __user *, uargs)

The use of SYSCALL_DEFINEx(func_name, args) is a fairly recent change
(well, January, 2009) that may be the reason why you think that there
has been a change. See;a=commit;h=1a94bc34768e463a93cb3751819709ab0ea80a01
