+[MIPS] Fix for gettimeofday jumping backwards, then forwards.
+
+Below are 2 fixes to do with time jumping around as reported by
+gettimeofday(). One is SB1250 specific and one appears generic.
+
+The symptom is revealed by running multile copies (1 per cpu) of a
+simple test program that calls gettimeofday() as fast as possible
+looking for time to go backwards.
+
+When a jump is detected the program outputs a few samples before and
+after each jump:

+
+Time jumps backwards 1msec then forwards 1msec a few usec
+later. Usually lasts < 2us but I've seen it as long as 5us if the
+system is under load.
+
+First problem I found is that sb1250_gettimeoffset() simply reads the
+current cpu 0 timer remaining value, however once this counter reaches
+0 and the interrupt is raised, it immediately resets and begins to
+count down again.
+
+If sb1250_gettimeoffset() is called on cpu 1 via do_gettimeofday()
+after the timer has reset but prior to cpu 0 processing the interrupt
+and taking write_seqlock() in timer_interrupt() it will return a
+full value (or close to it) causing time to jump backwards 1ms. Once
+cpu 0 handles the interrupt and timer_interrupt() gets far enough
+along it will jump forward 1ms.
+
+To fix this problem I implemented mips_hpt_*() on sb1250 using a spare
+timer unrelated to the existing periodic interrupt timers. It runs at
+1Mhz with a full 23bit counter. This eliminated the custom
+do_gettimeoffset() for sb1250 and allowed use of the generic
+fixed_rate_gettimeoffset() using mips_hpt_*() and timerhi/timerlo.
+
+The second problem is that more of timer_interrupt() needs to be
+protected by xtime_lock:
+
+* do_timer() expects the arch-specific handler to take the lock as it
+ modifies jiffies[_64] and xtime.
+* writing timerhi/lo in timer_interrupt() will mess up
+ fixed_rate_gettimeoffset() which reads timerhi/lo.
+
+With both changes do_gettimeofday() works correctly on both cpu 0 and
+cpu 1.
+
+Other changes/cleanups:
+
+The existing sb1250 periodic timers were slow by 999ppm (given a
+perfect 100mhz reference). The timers need to be loaded with 1 less
+than the desired interval not the interval itself.
+
+M_SCD_TIMER_INIT and M_SCD_TIMER_CNT had the wrong field width (should
+be 23 bits not 20 bits)
