Upstream commit e66eed651fd18a961f11cda62f3b5286c8cc4f9f
"list: remove prefetching from regular list iterators"
removed <linux/prefetch.h> from <linux/list.h> very early in the v3.0 dev cycle (v2.6.39-2-ge66eed6), thereby causing build failures when it exposed the implicit prefetch users in parisc.

[ The parisc defconfig has been failing to build everywhere since last May! http://kisskb.ellerman.id.au/kisskb/target/2059/ And this one liner fix https://lkml.org/lkml/2011/10/15/121 was reported last Oct, and again http://www.spinics.net/lists/linux-parisc/msg03945.html in early Feb. So, now with a clear reasoning in the commit header as to why it fails, can we finally get this in tree please? ]
