What:	Multipath cached routing support in ipv4

When:	in 2.6.23

Why:	Code was merged, then submitter immediately disappeared leaving

	us with no maintainer and lots of bugs.  The code should not have

	been merged in the first place, and many aspects of it's

	implementation are blocking more critical core networking

	development.  It's marked EXPERIMENTAL and no distribution

	enables it because it cause obscure crashes due to unfixable bugs

	(interfaces don't return errors so memory allocation can't be

	handled, calling contexts of these interfaces make handling

	errors impossible too because they get called after we've

	totally commited to creating a route object, for example).

	This problem has existed for years and no forward progress

	has ever been made, and nobody steps up to try and salvage

	this code, so we're going to finally just get rid of it.

What:	read_dev_chars(), read_conf_data{,_lpm}() (s390 common I/O layer)

When:	December 2007

Why:	These functions are a leftover from 2.4 times. They have several
