PROC_FS is a bool, so this code is either present or absent. It will never be modular, so using module_init as an alias for __initcall is rather misleading. Fix this up now, so that we can relocate module_init from init.h into module.h in the future. If we don't do this, we'd have to add module.h to obviously non-modular code, and that would be ugly at best. Note that direct use of __initcall is discouraged, vs. one of the priority categorized subgroups. As __initcall gets mapped onto device_initcall, our use of fs_initcall (which makes sense for fs code) will thus change these registrations from level 6-device to level 5-fs (i.e. slightly earlier). However no observable impact of that small difference has been observed during testing, or is expected. Also note that this change uncovers a missing semicolon bug in the registration of vmcore_init as an initcall.
