Atomic readq and writeq do not exist by default on some 32bit architectures, thus causing compile errors due to non-existent symbols. Since NTB has not been tested 32bit, disable x86_32 support until such time as this and any other issues can be properly discovered.

The PCI-E Non-transparent bridge hardware is a point-to-point PCI-E bus
|
|
connecting 2 systems. When configured, writes to the device's PCI
|
|
mapped memory will be mirrored to a buffer on the remote system. The
|
|
ntb Linux driver uses this point-to-point communication as a method to
|
|
transfer data from one system to the other.

If unsure, say N.
