Greg,
Would you please cherry pick the following 26 patches from mainline to
4.9.y stable branch? (applied top to bottom)

I verified that they cherry-pick cleanly, and boot on x86_64 and
arm64.  I will follow up with more patches cleaning up the warnings,
adding arm 32b support, and the backport patches themselves when they
do not cherry pick cleanly.
