Linux 4.20 rc4

The patch stats this week look a little bit more normal than last time,probably simply because it's also a normal-sized rc4 rather than theunusually small rc3.So this time around, about 60% of the patch is drivers (networking,HID, gpu, usb, mtd..) which is the usual distribution. The rest beinga random mix of networking, filesystem fixes, arch updates,Documentation etc. And some fixes to the new xarray code.Nothing looks particularly odd or scary, although we do have someknown stuff still pending. For example, the STIBP fixes are stillbeing discussed and fine-tuned and haven't been merged yet. Andthere's a few mm fixes being talked about. Nothing that should keeppeople from testing the 4.20 rc's, though, so go out and test.One thing I did forget to mention last rc, but did come up in some ofthe pull request threads, and that people might have noticed that way:I've stopped doing the manual pull request acknowledgement emails,because Konstantin's automation to do it has gone live and is workingwell. It's worth pointing out, though, that the automation only worksfor pull requests that have been cc'd to mailing lists that are beingtracked by the lore.kernel.org archives, and have an email addressthat matches "linux-*". So that's obviously mainly LKML, but it doestrigger for linux-block too, for example.The reason I'm mentioning it is that if you're not seeing the pullrequest automation emails, it might be because you didn't cc a listthat is getting tracked..
