2012-07-01dmaengine: PL08x: get rid of write only pool_ctr and free_txd lockingRussell King
The free function says the pl08x lock should be taken before calling it. However, the DMA pool allocation/freeing is already properly locked. The only thing that would need this is pool_ctr, which happens to be a write-only variable. Let's get rid of this, and eliminate any need for additional locking here.

2012-07-01dmaengine: PL08x: fix tx_status function to return correct residueRussell King
Now that we're converted to use the generic vchan support, we can fix the residue return from tx_status to be compliant with dmaengine. This returns the number of bytes remaining for the _specified_ cookie, not the number of bytes in all pending transfers on the channel.

2012-07-01dmaengine: PL08x: rejig physical channel allocationRussell King
Rework the physical channel allocation mechanism to only allocate physical channels to virtual channels when they're about to be used. This eliminates all the complexity with holding channels while descriptors are being prepared, which is completely unnecessary. This also brings this driver to a state where the generic virtual DMA code can be used with this driver, and opens up the possibility of properly scheduling and prioritorising physical DMA channels to virtual DMA channels.

The acpi_pad driver can get stuck in destroy_power_saving_task() waiting for kthread_stop() to stop a power_saving thread. The problem is that the isolated_cpus_lock mutex is owned when destroy_power_saving_task() calls kthread_stop(), which waits for a power_saving thread to end, and the power_saving thread tries to acquire the isolated_cpus_lock when it calls round_robin_cpu().
