Subject: [PATCH 04/11] ia64: sync struct siginfo with general version


From: Dave Hansen <dave.hansen@...ux.intel.com>


New fields about bound violation are added into general struct
siginfo. This will impact MIPS and IA64, which extend general
struct siginfo. This patch syncs this struct for IA64 with
general version.
