Subject: [PATCH] [POWERPC] arch/powerpc/platforms/iseries/pci.c: Use time_*
 macros
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The functions time_before, time_before_eq, time_after, and
time_after_eq are more robust for comparing jiffies against other
values.

This implements usage of the time_after() macro, defined at
linux/jiffies.h, which deals with wrapping correctly.
