The intermittent scheduling of the migration thread at ultra high priority makes the smp nice handling see that runqueue as being heavily loaded. The migration thread itself actually handles the balancing so its influence on priority balancing should be ignored. Signed-off-by:

The priority biasing was off by mutliplying the total load by the total priority bias and this ruins the ratio of loads between runqueues. This patch should correct the ratios of loads between runqueues to be proportional to overall load. -2nd attempt. From: Dave Kleikamp <shaggy@austin.ibm.com> This patch fixes a divide-by-zero error that I hit on a two-way i386 machine. rq->nr_running is tested to be non-zero, but may change by the time it is used in the division. Saving the value to a local variable ensures that the same value that is checked is used in the division. Signed-off-by:

To intensify the 'nice' support across physical cpus on SMP we can bias the loads on idle rebalancing. To prevent idle rebalance from trying to pull tasks from queues that appear heavily loaded we only bias the load if there is more than one task running. Add some minor micro-optimisations and have only one return from __source_load and __target_load functions. Fix the fact that target_load was not biased by priority when type == 0. Signed-off-by:

Real time tasks' effect on prio_bias should be based on their real time priority level instead of their static_prio which is based on nice. Signed-off-by:

prio_bias should only be adjusted in set_user_nice if p is actually currently queued. Signed-off-by:

This patch implements 'nice' support across physical cpus on SMP. It introduces an extra runqueue variable prio_bias which is the sum of the (inverted) static priorities of all the tasks on the runqueue. This is then used to bias busy rebalancing between runqueues to obtain good distribution of tasks of different nice values. By biasing the balancing only during busy rebalancing we can avoid having any significant loss of throughput by not affecting the carefully tuned idle balancing already in place. If all tasks are running at the same nice level this code should also have minimal effect. The code is optimised out in the !CONFIG_SMP case. Signed-off-by:

- Adds missing msp34xxg_reset to VIDIOC_S_STD (just like VIDIOCSCHAN). - Improves msp3400 debug messages. Now, all kernel message in msp3400.c use the same prefix and include the I2C bus to differentiate between multiple msp3400 I2C chips. - Correctly prints the chip identifier for the msp44xx chips. - msp34xxg cleanups.
