[GIT PULL] ARC updates for 4.19-rc3

[Vineet Gupta]

Hi Linus,

ARC updates for 4.19-rc3.

The DMA-IOC changes are technically merge-window stuff but that didn't happen due
to me being in fire drill inhouse. They have been reviewed a while back by
Christoph and it will help him with more DMA rework if merged now than in 4.20, so
please take them.

Please pull !

Thx,
-Vineet
