params: add 3rd arg to option handler callback signature
Add a 3rd arg, named "doing", to unknown-options callbacks invoked from parse_args(). The arg is passed as: "Booting kernel" from start_kernel(), initcall_level_names[i] from do_initcall_level(), mod->name from load_module(), via parse_args(), parse_one() parse_args() already has the "name" parameter, which is renamed to "doing" to better reflect current uses 1,2 above. parse_args() passes it to an altered parse_one(), which now passes it down into the unknown option handler callbacks. The mod->name will be needed to handle dyndbg for loadable modules, since params passed by modprobe are not qualified (they do not have a "$modname." prefix), and by the time the unknown-param callback is called, the module name is not otherwise available. Minor tweaks: Add param-name to parse_one's pr_debug(), current message doesnt identify the param being handled, add it. Add a pr_info to print current level and level_name of the initcall, and number of registered initcalls at that level. This adds 7 lines to dmesg output, like: initlevel:6=device, 172 registered initcalls Drop "parameters" from initcall_level_names[], its unhelpful in the pr_info() added above. This array is passed into parse_args() by do_initcall_level().
