signal/ia64: Move the ia64 specific si_codes to asm-generic/siginfo.h
Having si_codes in many different files simply encourages duplicate definitions that can cause problems later. To avoid that merge the ia64 specific si_codes into uapi/asm-generic/siginfo.h Update the sanity checks in arch/x86/kernel/signal_compat.c to expect the now lager NSIGILL and NSIGFPE. As nothing excpe the larger count is exposed on x86 no additional code needs to be updated. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
