Subject: [PATCH] documentation: fix broken lkml archive links in RCU requirements

Fix 4 LKML archive links that became broken (data loss
on mail-archive.com?)

Working links were found on Paul McKenney's RCU articles
on LWN.net, from which the documentation originates:
http://lwn.net/Articles/652156/
