[PATCH] Time: i386 Conversion - part 3: Enable Generic Timekeeping
This converts the i386 arch to use the generic timeofday subsystem. It enabled the GENERIC_TIME option, disables the timer_opts code and other arch specific timekeeping code and reworks the delay code. While this patch enables the generic timekeeping, please note that this patch does not provide any i386 clocksource. Thus only the jiffies clocksource will be available. To get full replacements for the code being disabled here, the timeofday-clocks-i386 patch will needed.

7 * struct timer_ops - used to define a timer source
8 *
9 * @name: name of the timer.
10 * @init: Probes and initializes the timer. Takes clock= override
11 * string as an argument. Returns 0 on success, anything else
12 * on failure.
13 * @mark_offset: called by the timer interrupt.
14 * @get_offset: called by gettimeofday(). Returns the number of microseconds
15 * since the last timer interupt.
16 * @monotonic_clock: returns the number of nanoseconds since the init of the
17 * timer.
18 * @delay: delays this many clock cycles.
