[MIPS] Sibyte: Fix race in sb1250_gettimeoffset().

2006-03-18T16:59:30+00:00

    
From Dave Johnson :
    
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.
    
Fix this problem by implementing 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.

[MIPS] Sibyte: Fix interrupt timer off by one bug.

2006-03-18T16:59:30+00:00

    
From Dave Johnson :
    
The timers need to be loaded with 1 less than the desired interval not
the interval itself.

[MIPS] Protect more of timer_interrupt() by xtime_lock.

2006-03-18T16:59:29+00:00

    
From Dave Johnson :

* 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.

[MIPS] local_r4k_flush_cache_page fix

2006-03-18T16:59:27+00:00

    
If dcache_size != icache_size or dcache_size != scache_size, or
set-associative cache, icache/scache does not flushed properly.  Make
blast_?cache_page_indexed() masks its index value correctly.  Also,
use physical address for physically indexed pcache/scache.
