You probably should not set this one.

And almost certainly not this one.

These seem unlikely as well. Can you confirm that you have both old-style
PC-Card support and RAPIDIO support on your most common hardware?

Is this an on-board PCI device you actually have?
What do you connect to the PC parport? Most printers
in the past 15 years only have USB or network connections.

Do you actually support legacy PCI slots?

I don't see any device tree support in your patches, so I think the
SERIAL_OF_PLATFORM is not needed.

This is gone now.

You don't seem to enable any infiniband host drivers, so the core
layer can probably remain turned off

same for UIO.

I would generally recommend using EXT4 over EXT2 or EXT3

On 64-bit platforms, you probably want to increase this a bit,
otherwise you get extra warnings about code that works as
intended. The default is 2048, but you should be able to get by
with 1280, if that lets you build a defconfig kernel without warnings.
