This is an audit (copy_*_user), cleanup, and coding-style fix
for this driver.

As noted by Gergely Nagy:

  "devfs_mk_cdev() first checks the mode passed to it, and if it thinks
   it is not a char device, it prints a warning and aborts.  Now, this
   printing involves the local variable `buf' (char buf[64]), which is
   not initialised at that point."

The same problem also affects devfs_mk_bdev.

Fixed thus.

  "I'm working on updating the ia64 tree with local_t etc.  One
   thing that would really help me: could you make
   asm-generic/percpu_modcopy() a macro?  The routine depends on
   cpu_possible(), but I can't including smp.h in percpu.h since
   that would lead to recusive header-file dependencies (and in my
   opinion, percpu.h should be more "primitive" than smp.h, so that
   it can be included virtually everywhere)."

A few places pre-declare "int module_init(void);" and "void
module_cleanup(void);".  Other than being obsolete, this is
unneccessary (it's in init.h anyway).

There are still about 100 places which still use the
obsolete-since-2.2 "a function named module_init() magically gets
called": this change frees us up implement that via a macro.
