Did you disable these intentionally? Its a kernel tinification option
that is rarely used in defconfigs.

Likewise, intentional? Its another tinification option that isn't all
that commonly used in defconfigs.

Likewise, intentional? I don't think inotify is deprecated in favour of
anything else yet (it appears to superscede dnotify).

Likewise.

Particular reason to disable these two compile time warnings?

Did you mean to leave this turned on?

I believe you can specify an earlyprintk address on command line. Would
it be preferable to do that rather than hard coding the address in the
platform code?
