Again, I prefer Greg to take these through his tty tree.

Changes done by this serie:

1) Create termbits-common.h for the most obvious termbits.h intersection.
2) Reformat some lines that remain in termbits.h files.
3) Don't include posix_types.h unnecessarily.

Please do check I got the uapi include things done correctly! That is,
that including using asm-generic/termbits-common.h path is the preferred
approach for a header file that is not supposed to be overridden by the
arch specific header files and that mandatory-y is not required for
termbits-common.h.

Unfortunately I couldn't move also tcflag_t into termbits-common.h due
to the way it is being defined for sparc. However, by the looks of how
the type for tcflag_t is being chosen there, having just unsigned int
might work also for sparc?

Ilpo Järvinen (3):
  termbits.h: create termbits-common.h for identical bits
  termbits.h: Align lines & format
  termbits.h: Remove posix_types.h include

Some defines are the same across all archs. Move the most obvious
intersection to termbits-common.h.

I like your cleanup patches, but in this specific one, does it makes sense
to split up together-belonging constants, e.g.

In the hunk above you leave IUCLC, IXON, IXOFF... because they seem unique to parisc.
The other defines are then taken from generic header.
Although this is correct, it leaves single values alone, which make it hard to verify
because you don't see the full list of values in one place.

Here all baud values are dropped and will be taken from generic header, which is good.

That said, I think it's good to move away the second hunk,
but maybe we should keep the first as is?

It's just a thought. Either way, I'm fine your patch if that's the
way which is decided to go for all platforms.

While I too am fine either way, I don't think these are as strongly 
grouped as you seem to imply. There's no big advantage in having as much 
as possible within the same file. If somebody is looking for the meaning 
of these, these headers are no match when compared e.g. with stty manpage.

For c_iflag, the break, parity and cr related "groups" within c_iflag are 
moving completely to common header.

IXANY is probably only one close to borderline whether it kind of belongs 
to the same group as IXON/IXOFF (which both by chance both remained on the 
same side in the split). I don't think it does strongly enough to warrant 
keeping them next to each other but I'm open what opinions others have on 
it.

The rest in c_iflag don't seem to be strongly tied/grouped to the other 
defines within c_iflag. They're just bits that appear next/close to each 
other but are not tied by any significant meaning-based connection.

C_oflag is more messy. I exercised grouping based judgement with c_oflag 
where only the defines with all bits as zero would have moved to the 
common header breaking the groups very badly. That is, only CR0 would have 
moved and CR1-3 remained in arch headers, etc. which made no sense to do. 
One could argue, that since ONLCR (and perhaps CRDLY) are not moving, no 
other cr related defines should move either.

Yes, lets wait and see what the others think.

  Cc: Ilpo Järvinen

- Align c_cc defines.
- Remove extra newlines.
- Realign & adjust number of leading zeros.
- Reorder c_cflag defines to ascending order
- Make comment ending shorted (=remove period and one extra space from
  the comments in mips).
