Subject: [PATCHv4 net-next 00/13] net: mvpp2: misc improvements and preparation patches

David,

This series contains a number of fixes, misc improvements and
preparation patches for an upcoming series that adds support for the
new PPv2.2 network controller to the mvpp2 driver.

The most significant improvements are:

 - Switching to using build_skb(), which is necessary for the upcoming
   PPv2.2 support, but anyway a good improvement to the current mvpp2
   driver (supporting PPv2.1).

 - Making the driver build on 64-bit platforms.

Changes since v3:

 - Addition of a patch "net: mvpp2: fix DMA address calculation in
   mvpp2_txq_inc_put()", which fixes a bug in the driver in the
   calculation of DMA addresses. This bug was found using
   DMA_API_DEBUG.

 - Modify the "net: mvpp2: switch to build_skb() in the RX path" patch
   to recalculate the fragment size when the MTU is changed in
   mvpp2_bm_update_mtu().

 - Added Acked-by from Russell King on all patches, except:

    * "net: mvpp2: fix DMA address calculation in
      mvpp2_txq_inc_put()", because it's a new patch

    * "net: mvpp2: switch to build_skb() in the RX path" because I
      modified it since the v3.

 - Rebased on top of 4.10.

Changes since v2:

 - Fix remaining 64-bit build warning, reported by David Miller.

 - Adjust how bit mask related definitions are done in "net: mvpp2:
   simplify MVPP2_PRS_RI_* definitions" according to Russell King
   suggestions.

 - Add a patch "net: mvpp2: remove useless arguments in
   mvpp2_rx_{pkts,time}_coal_set", suggested by Russell King.

 - Rework mvpp2_rx_time_coal_set() implementation to avoid overflows
   and rounding errors. I've used the implementation suggested by
   Russell King.

Changes since v1:

 - This series is split as a separate series from the larger patch set
   adding support for PPv2.2 in the mvpp2 driver, as requested by
   David Miller.

 - Rebased on top of v4.10-rc1.

Thanks!

Thomas
