From 8450e85399031a192ffb34f0f9ac981173db6a31 Mon Sep 17 00:00:00 2001 From: Alexander van Heukelum Date: Sat, 5 Jul 2008 19:53:46 +0200 Subject: [PATCH] x86, cleanup: fix description of __fls(): __fls(0) is undefined Ricardo M. Correia spotted that the use of __fls() in fls64() did not seem to make sense. In fact fls64()'s implementation is fine, but the description of __fls() was wrong. Fix that. Reported-by: "Ricardo M.
