Those are not "problems".
When you take an older .config file and use it with a newer kernel the options need to be updated...
Options that are no longer available are just dropped.
New options that have not existed before are prompted - Taking the default is usually the best practice, but you can lookup the topic and decide on whether to include them or not.
One option you have is to just disable them. This is only a problem if a new option supersedes the functionality of an older option that has been discarded. For example, a completely new driver for video cards also handles the older video card. thus the old option is removed, but the new one has not been selected. In this case, taking the default (which usually to make it a module) would be the appropriate response. In other cases (like wireless drivers), you didn't use the old one and had it disabled, but the new driver is still not used... making disabling the new one appropriate.
But without knowing the subject the easiest, (and usually safest) is to take the default.
