Subject: [patch -next] x86: dubious one-bit signed bitfields
Date: Wed, 07 Dec 2011 06:38:49 +0000	[thread overview]
Message-ID: <20111207063848.GA14507@elgon.mountain> (raw)

It doesn't cause any runtime problems in this case, but bitfields should
be unsigned.  This file gets included a lot so it generates thousands of
Sparse warnings about dubious one-bit signed bitfields.
