These look a lot longer than they should be, they contain many symbols
that I suspenc
are not needed or useful for you.

This is not a well-formed hostname

Disabling swap, fhandle or AIO seems odd, those are commonly
used symbols.

CONFIG_EMBEDDED should generally not be selected, it's only for
very unusual configurations that need to disable symbols that are
normally required.

oprofile can go now, since you said you'd remove the code.

These block device configuration options all seem misplaced
here, it's extremely unlikely that you need them.

I would guess you want IPV6 but not WEXT here.

No need to turn this off, it might just get in the way of build
testing.

There are many input devices listed here, most of which you almost
certainly won't need.

Are you sure you have IPMI hardware?

For new platforms, using the DRM subsystem is the recommend
way to do graphics, it mostly replaces the framebuffer subsystem
here.

I think this is no longer there.

Better use EXT4 for the defconfig instead.
