Pull tty/serial updates from Greg KH:
 "Here's the tty/serial patchset for 4.10-rc1.

  It's been a quiet kernel cycle for this subsystem, just a small number
  of changes. A few new serial drivers, and some cleanups to the old
  vgacon logic, and other minor serial driver changes as well.

  All of these have been in linux-next for a while with no reported
  issues"

Linux now has some ability to manipulate cursor appearance. Normally, you
can set the size of hardware cursor (and also work around some ugly bugs in
those miserable Trident cards [#f1]_. You can now play a few new tricks:
you can make your cursor look
like a non-blinking red block, make it inverse background of the character it's
over or to highlight that character and still choose whether the original
hardware cursor should remain visible or not. There may be other things I have
never thought of.
