[PATCH] Mark longhaul driver as broken.

[CPUFREQ] Mark longhaul driver as broken.
This seems to work for a short period of time, but when
used in conjunction with a userspace governor that changes
the frequency regularly, it's only a matter of time before
everything just locks up.

[PATCH] powerpc: make ISA floppies work again

2006-04-07T16:44:27+00:00

We used to assume that a DMA mapping request with a NULL dev was for
ISA DMA.  This assumption was broken at some point.  Now we explicitly
pass the detected ISA PCI device in the floppy setup.

[PATCH] Fix speedstep-smi assembly bug in speedstep_smi_ownership

2006-03-28T06:47:31+00:00

Fix bug identified by Linus Torvalds : the `out'
instruction depends upon the state of memory_data[], so we need to tell gcc
that before executing it. (The opcode, not gcc).

Fixes http://bugzilla.kernel.org/show_bug.cgi?id=5553

Thanks to Antonio Ospite  for testing.

[PATCH] DMI: fix DMI onboard device discovery

2006-03-28T06:47:31+00:00

Attached patch fixes invalid pointer arithmetic in DMI code to make onboard
device discovery working again.

akpm: bug has been present since dmi_find_device() was added in 2.6.14.
Affects ipmi only (I think) - the symptoms weren't described.

akpm: changed to use pointer arithmetic rather than open-coded sizeof.

[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.
