The reason I am doing so is that it can make use of compiler supported builtin functions which can leverage hardware. As I need this for a fix in the ipv6 stack, which is also included in this series, I propose to add it sooner than later over Davem's net tree. This is also the reason why I start slowly with only the one function I need at this time. ==================== Signed-off-by: David S. Miller --- ec3661b42257d9a06cf0d318175623ac7a660113
