[PATCHv3 0/3] mv_xor improvements

[Thomas Petazzoni]

Hello Vinod,

Here is the third iteration of some mv_xor improvements patches. The
previous iteration was sent in July earlier this year. Compared to the
v2:

 - rebased on top of v4.4-rc1

 - dropped patches that were merged

 - as you suggested, add a comment in the code to explain that our
   suspend/resume implementation makes the assumption that there are
   no in-flight DMA transactions because mv_xor is only used for
   RAID5, and the block layer will have already suspended I/O
   activity, so not special care needs to be taken in the driver
   itself.

I have retested this with a RAID5 array on Armada 388 GP, while the
array is in reconstruction, and doing some suspend/resume cycles in
the middle.

Thanks!

Thomas
