[GIT PULL] libnvdimm for v5.9

[Verma, Vishal L]

Hi Linus, please pull from:

  git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm.git/
tags/libnvdimm-for-5.9

...to receive a new feature in libnvdimm - 'Runtime Firmware
Activation', and a few small cleanups and fixes in libnvdimm and DAX.

You'd normally receive this pull request from Dan Williams, but he's
busy watching a newborn (Congrats Dan!), so I'm watching libnvdimm this
cycle.

I'd originally intended to make separate topic-based pull requests - one
for libnvdimm, and one for DAX, but some of the DAX material fell out
since it wasn't quite ready. I ended up merging the two branches into
one, and hence a couple of 'internal' merges - I hope these are ok. If
you prefer that I should've handled this differently please let me know!

I was also expecting a potential conflict - I was assuming Greg had
pulled in one of Dan's patches[1] through driver-core, but I don't see
it in his tree, and a test merge with the current master went through
cleanly.

There were a small handful of late fixes, but everything has had at
least a week of -next soak time without any reported issues. We've also
received a positive build notification from 0-day.
