Merge tag 'tty-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty / serial updates from Greg KH:
"Here is the big set of tty and serial driver patches for 5.14-rc1.

A bit more than normal, but nothing major, lots of cleanups.
Highlights are:

- lots of tty api cleanups and mxser driver cleanups from Jiri

- build warning fixes

- various serial driver updates

- coding style cleanups

- various tty driver minor fixes and updates

- removal of broken and disable r3964 line discipline (finally!)

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

tty: cumulate and document tty_struct::flow* members

Group the flow flags under a single struct called flow. The new struct
contains 'stopped' and 'tco_stopped' bools which used to be bits in a
bitfield. The struct also contains the lock protecting them to
potentially share the same cache line.

Note that commit c545b66c6922b (tty: Serialize tcflow() with other tty
flow control changes) added a padding to the original bitfield. It was
for the bitfield to occupy a whole 64b word to avoid interferring stores
on Alpha (cannot we evaporate this arch with weird implications to C
code yet?). But it doesn't work as expected as the padding
(tty_struct::unused) is aligned to a 8B boundary too and occupies some
bytes from the next word.

So make it reliable by:
1) setting __aligned of the struct -- that aligns the start, and
2) making 'unsigned long unused[0]' as the last member of the struct --
pads the end.

This is also the perfect time to start the documentation of tty_struct
where all this lives. So we start by documenting what these bools
actually serve for. And why we do all the alignment dances. Only the few
up-to-date information from the Theodore's comment made it into this new
Kerneldoc comment.

Merge tag 'tty-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

Pull tty and serial driver updates from Greg KH:
"Here is the big set of tty and serial driver updates for 5.13-rc1.

Actually busy this release, with a number of cleanups happening:

- much needed core tty cleanups by Jiri Slaby

- removal of unused and orphaned old-style serial drivers. If anyone
shows up with this hardware, it is trivial to restore these but we
really do not think they are in use anymore.

- fixes and cleanups from Johan Hovold on a number of termios setting
corner cases that loads of drivers got wrong as well as removing
unneeded code due to tty core changes from long ago that were never
propagated out to the drivers

- loads of platform-specific serial port driver updates and fixes

- coding style cleanups and other small fixes and updates all over
the tty/serial tree.

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