I followed in the footsteps of 'ghes_disable', which is also a kernel

Ok, ghes_disable comment says that using module_param() is easier.
ghes_edac is not a module but then __setup() is for "really core code".

Documentation/admin-guide/kernel-parameters.rst also talks about
core_param() but that's #ifndef MODULE. So module_param() it is.
