The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

virtio requests are scatter-gather-style descriptors, but no
assumptions should be made about the layout. lguest was lazy here,
but saved by the fact that the network device hands all requests to
tun (which does it correctly) and console and random devices simply
use readv and writev.
Block devices, however, are broken: we convert to iovecs internally,
just make sure we handle the correctly.

We usually got away with ->next on the final entry being NULL, but it
finally bit me.

This is a better location instead of having it in Documentation.
