From acf0108a84edae22b99655eb2f6f6c9f7ec4d449 Mon Sep 17 00:00:00 2001 From: Harvey Harrison Date: Sat, 18 Oct 2008 20:28:36 -0700 Subject: byteorder: use generic C version for value byteswapping This makes the new implementation of the byteorder helpers match the old in how it degraded when an arch-defined version was not available: 1) swab() - look for arch defined - if not, use generic c version 2) swabp() - look for arch-defined - if not, deref pointer and use swab() 3) swabs() - look for arch defined - if not, use swabp Signed-off-by: Harvey Harrison Cc: "David S.
