[GIT PULL] ARC updates for 4.19-rc3

[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

That "tags/arc-4.19-rc3" actually a real signed tag from you, but it
doesn't point to any of your new work. In fact, it just points to my
"Linux 4.15-rc1" commit from last year.

Which is presumably also why your pull request didn't contain a diffstat.

Hmm?

Sorry my bad. I did glance at the truncated output and wondered if this was some
git behavior chg.
But turns out I'd passed wrong branch to my script ! Now with right stuff. Thx.
