[IA64] arch/ia64/kernel/: use time_* macros
The functions time_before, time_before_eq, time_after, and time_after_eq are more robust for comparing jiffies against other values. So use the time_after() & time_before() macros, defined at linux/jiffies.h, which deal with wrapping correctly [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: S.Caglar Onur <caglar@pardus.org.tr> Reviewed-by: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Tony Luck <tony.luck@intel.com>
