      pch_dma: fix DMA issue(ch8-ch11) · c3d4913c
      由 Tomoya MORINAGA 提交于 
      ISSUE: In case PCH_DMA with I2S communications with ch8~ch11, sometimes I2S data
is not send correctly.
CAUSE: The following patch I submitted before was not enough modification for
supporting DMA ch8~ch11. The modification for status register of ch8~11 was not
enough.

This patch fixes the issue.
We can confirm PCH_DMA with I2S communications with ch8~ch11 works well.

      dmaengine: shdma: Fix up fallout from runtime PM changes. · 5c2de444
      由 Paul Mundt 提交于 
      The runtime PM changes introduce sh_dmae_rst() wrapping via the
runtime_resume helper, depending on dev_get_drvdata() to fetch the
platform data needed for the DMAOR initialization default at a time
where drvdata hasn't yet been established by the probe path, resulting
in general probe misery:

      Add appropriate <linux/prefetch.h> include for prefetch users · 70c71606
      由 Paul Gortmaker 提交于 
      After discovering that wide use of prefetch on modern CPUs
could be a net loss instead of a win, net drivers which were
relying on the implicit inclusion of prefetch.h via the list
headers showed up in the resulting cleanup fallout.  Give
them an explicit include via the following $0.02 script.

 =========================================
 #!/bin/bash
 MANUAL=""
 for i in `git grep -l 'prefetch(.*)' .` ; do
 	grep -q '<linux/prefetch.h>' $i
 	if [ $? = 0 ] ; then
 		continue
 	fi

 	(	echo '?^#include <linux/?a'
 		echo '#include <linux/prefetch.h>'
 		echo .
 		echo w
 		echo q
 	) | ed -s $i > /dev/null 2>&1
 	if [ $? != 0 ]; then
 		echo $i needs manual fixup
 		MANUAL="$i $MANUAL"
 	fi
 done

      dmaengine: shdma: synchronize RCU before freeing, simplify spinlock · 31705e21
      由 Guennadi Liakhovetski 提交于 
      List elements, deleted using list_del_rcu(), cannot be freed without
synchronising RCU. Further, the spinlock, used to protect the RCU
writer, is called in process context, so, we don't have to save flags.
