From 5cdcc22f25b0766fe16d5dd8e3b2efc91fa4da6e Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Mon, 2 Jun 2008 21:30:38 +1000 Subject: [CRYPTO] rmd: Use pointer form of endian swapping operations This patch converts the relevant code in the rmd implementations to use the pointer form of the endian swapping operations. This allows certain architectures to generate more optimised code. For example, on sparc64 this more than halves the CPU cycles on a typical hashing operation. Based on a patch by David Miller.
