[akpm]

     Subject: kbuild: disable -Wformat-truncation warnings by default
has been removed from the -mm tree.  Its filename was
     kbuild-disable-wformat-truncation-warnings-by-default.patch

This patch was dropped because an alternative patch was merged

------------------------------------------------------
From: Arnd Bergmann <arnd@arndb.de>
Subject: kbuild: disable -Wformat-truncation warnings by default

With x86 allmodconfig, we currently get 233 -Wformat-truncation warnings,
which makes the entire warnings rather useless.

This turns off the warning by default, unless we specify W=1 or higher
