<content type='text'>
The tasklet checks RAW.BLOCK twice, and does not check RAW.XFER. This is
obviously wrong, and could theoretically cause the driver to hang.

If you are using linked lists for queues list_splice() will not do what
you would expect even if you use the elements passed reversed. We need
to handle these differently. We add list_splice_tail() and
list_splice_tail_init().

This patch adds to ioatdma and dca modules
support for Intel I/OAT DMA engine ver.3 (aka CB3 device).
The main features of I/OAT ver.3 are:
 * 8 single channel DMA devices (8 channels total)
 * 8 DCA providers, each can accept 2 requesters
 * 8-bit TAG values and 32-bit extended APIC IDs

<title>I/OAT: tcp_dma_copybreak default value dependent on I/OAT version</title>

I/OAT DMA performance tuning showed different optimal values of
tcp_dma_copybreak for different I/OAT versions (4096 for 1.2 and 2048
for 2.0).  This patch lets ioatdma driver set tcp_dma_copybreak value
according to these results.

<title>I/OAT: Add watchdog/reset functionality to ioatdma</title>

<content type='text'>
Due to occasional DMA channel hangs observed for I/OAT versions 1.2 and 2.0
a watchdog has been introduced to check every 2 seconds
if all channels progress normally.
If stuck channel is detected, driver resets it.
The reset is done in two parts. The second part is scheduled
by the first one to reinitialize the channel after the restart.
