arch/alpha/kernel/traps.c: 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 implement usage of the time_after() macro, defined in linux/jiffies.h, which deals with wrapping correctly [akpm@linux-foundation.org: fix warning] Signed-off-by: S.Caglar Onur <caglar@pardus.org.tr> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
