From 0cb6c969ed9de43687abdfc63714b6fe4385d2fc Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Wed, 10 Dec 2014 16:33:12 +0100 Subject: net, lib: kill arch_fast_hash library bits As there are now no remaining users of arch_fast_hash(), lets kill it entirely. This basically reverts commit 71ae8aac3e19 ("lib: introduce arch optimized hash library") and follow-up work, that is f.e., commit 237217546d44 ("lib: hash: follow-up fixups for arch hash"), commit e3fec2f74f7f ("lib: Add missing arch generic-y entries for asm-generic/hash.h") and last but not least commit 6a02652df511 ("perf tools: Fix include for non x86 architectures").
