[merged] kbuild-fix-kernel-boundsc-w=1-warning.patch removed from -mm tree

[akpm]

The patch titled
     Subject: kbuild: fix kernel/bounds.c 'W=1' warning
has been removed from the -mm tree.  Its filename was
     kbuild-fix-kernel-boundsc-w=1-warning.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
From: Arnd Bergmann <arnd@arndb.de>
Subject: kbuild: fix kernel/bounds.c 'W=1' warning

Building any configuration with 'make W=1' produces a warning:

kernel/bounds.c:16:6: warning: no previous prototype for 'foo' [-Wmissing-prototypes]

When also passing -Werror, this prevents us from building any other files.
Nobody ever calls the function, but we can't make it 'static' either
since we want the compiler output.

Calling it 'main' instead however avoids the warning, because gcc
does not insist on having a declaration for main.
