This patch cleans up some timeouts in the IDE subsystem.  The changes are
all minor and obvious, and have been in use here for some time.

* change jiffies checks to use time_after()
* add and use IDE_TIMEOUT_* macros

Please apply this for the next 2.4.x kernel, or let me know of any issues.

Thanks!

Tim
