Merged, compiled, and flashed onto my Pixel 2 XL and OnePlus 5.

No initial issues noticed in general usage or dmesg.

Just as a heads up for any other Pixel 2 (XL) users, there will be a
conflict in drivers/md/dm-bufio.c due to a Google backport. You can
simply take the mainline version of the patch and substitute READ_ONCE
for ACCESS_ONCE. I made a small video for thinking about these conflicts
if anyone cares for it: https://youtu.be/yWvU8_0O66A

OP5 merges in clean.

Thanks!
Nathan
