[PATCH] module_subsys: initialize earlier

[Mark Huang <mlhuang@CS.Princeton.EDU>]

Initialize module_subsys earlier (or at least earlier than devices) since it 
could be used very early in the boot process if kmod loads a module before the 
device initcalls. Otherwise, kmod will crash in 
kernel/module.c:mod_sysfs_setup() since the kset in module_subsys is not 
initialized yet.

I only noticed this problem because occasionally, kmod loads the modules for my 
SCSI and Ethernet adapters very early, during the boot process itself. I don't 
quite understand why it loads them sometimes and doesn't load them other times. 
Or who is telling kmod to do so. Can someone explain?

Please Cc: me on responses, thanks.
