Subject: [PATCH v2 0/4] I/OAT: watchdog/reset,
	tcp_dma_copybreak and I/OAT ver.3 support

This is version 2 of ioatdma patchset
which has been updated after first review comments.
The first three patches are a result of 
ioatdma sustaining and performance tuning efforts
for both I/OAT versions 1.2 and 2.0.
The fourth patch is a new patch in this set. 
It adds I/OAT version 3 support to ioatdma driver.

The main differences between v1 and v2 of this patchset are:
 * "Increase sleep time in ioat_dma_self_test" change 
   has been separated from 
   "Add watchdog/reset functionality to ioatdma driver" patch
 * tcp_dma_copybreak default value setting has been moved
   from dmaengine to ioatdma driver
 * "I/OAT version 3.0 support" patch has been added
 * checkpatch problems have been resolved

This patches apply to kernel 2.6.26-rc9.

     I/OAT: I/OAT version 3.0 support
