[GIT PULL] UML changes for 4.20-rc1

[Richard Weinberger]

Linus,

First of all, welcome back!

Please note that the vast majority of these changes have
been in -next since 4.18.
Due to vacation and other troubles I didn't send a pull request
back then.
I rebased them a few days ago on top of 4.19.

The following changes since commit 84df9525b0c27f3ebc2ebb1864fa62a97fdedb7d:

Pulled. I may not like recent rebases, but I do like this:

Okay, so my rebase was in vain, I thought you don't like pull requests
with such an old base.

Thanks,

Some *really* old bases can cause problems, but generally that's if
it's more than a year old (or if there's been some major upheaval that
happens to particularly strike your particular code).

Honestly, I don't think I can recall any actual "that is based on
something so old that it actually gets problematic" case ever having
happened.  But I could imagine it.

So if it's "a release or two", it's not worth rebasing for. Not unless
there is some other pressing reason (ie some screw-up that requires a
rebase).
