	Documentation/devicetree/bindings/net/micrel-ks8851.txt
	net/core/netpoll.c

The net/core/netpoll.c conflict is a bug fix in 'net' happening
to code which is completely removed in 'net-next'.

In micrel-ks8851.txt we simply have overlapping changes.

Although binutils currently supports use of this flag the details
concerning its effect upon the O32 ABI in userland are still being
worked on. In order to avoid userland becoming dependant upon current
behaviour before the details have been finalised, this option should
be considered experimental and only enabled by those working upon
