TTY/Serial fixes for 4.0-rc3

Browse source 
Here are some tty and serial driver fixes for 4.0-rc3.
 
 Along with the atime fix that you know about, here are some other serial
 driver bugfixes as well.  Most notable is a wait_until_sent bugfix that
 was traced back to being around since before 2.6.12 that Johan has fixed
 up.
 
 All have been in linux-next successfully.
