[PATCH] Builtin Module Parameters in sysfs too
Currently, only module parameters in loaded modules are exported in
/sys/modules/, while those of "modules" built into the kernel can be set by
the kernel command line, but not read or set via sysfs.
- move module parameters from /sys/modules/$(module_name)/$(parameter_name) to
/sys/modules/$(module_name)/parameters/$(parameter_name)
- remove dummy kernel_param for exporting refcnt, add "struct module *"-based
attribute instead
- also export module paramters for "modules" which are built into the kernel,
so parameters are always accessible at
/sys/modules/$(KBUILD_MODNAME)/$(parameter_name)
