I would very much like you to reconsider, Dave.

We can make them default to 'y' and hide them behind CONFIG_EMBEDDED,
and put in a scary help text that tells people _never_ to turn it off --
and hell, you can even make a taint flag for it if you like. But there
are a lot of people who really don't need these features and really want
the option of leaving them out.

Perhaps we should add a warning printk when one of these features is
'required' but absent. That would help to make it clear when someone has
disabled a feature which they shouldn't have disabled.

Refusing to apply the patches just means that either those people will
get them from elsewhere, or that their kernel will be more bloated than
it needs to be.
