Subject: [PATCH] Remove extra shift in __SI_CODE macro
From: "Robert H. de Vries" <rhdv () rhdv ! cistron ! nl>

Hi Linus,
The __SI_CODE macro shifts its argument 16 bits to the left while the only
argument used is already shifted 16 bits to the left. In this way no bits are
left on a 32 bit architecture.
Hence this patch, which removes the superfluous shift.
Robert
