Nothing in termbits seems to require anything from linux/posix_types.h.

- 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).

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

Many archs have termbits.h as octal numbers. It makes hard for humans
to parse the magnitude of large numbers correctly and to compare with
hex ones of the same define.
Convert octal values to hex.
First step is an automated conversion with:
for i in $(git ls-files | grep 'termbits\.h'); do
awk --non-decimal-data '/^#define\s+[A-Z][A-Z0-9]*\s+0[0-9]/ {
l=int(((length($3) - 1) * 3 + 3) / 4);
repl = sprintf("0x%0" l "x", $3);
print gensub(/[^[:blank:]]+/, repl, 3);
next} {print}' $i > $i~;
mv $i~ $i;
done
On top of that, some manual processing on alignment and number of zeros.
In addition, small tweaks to formatting of a few comments on the same
lines.

Alpha has had c_ispeed and c_ospeed, but still set speeds in c_cflags
using arbitrary flags. Because BOTHER is not defined, the general
Linux code doesn't allow setting arbitrary baud rates, and because
CBAUDEX == 0, we can have an array overrun of the baud_rate[] table in
drivers/tty/tty_baudrate.c if (c_cflags & CBAUD) == 037.
Resolve both problems by #defining BOTHER to 037 on Alpha.
However, userspace still needs to know if setting BOTHER is actually
safe given legacy kernels (does anyone actually care about that on
Alpha anymore?), so enable the TCGETS2/TCSETS*2 ioctls on Alpha, even
though they use the same structure. Define struct termios2 just for
compatibility; it is the exact same structure as struct termios. In a
future patchset, this will be cleaned up so the uapi headers are
usable from libc.

XTABS is an old name for "expand tabs to spaces" flag, which was a
separate flag on some BSD implementations. POSIX, however, specifies
that this effect is enabled with TAB3 output mode.
Currently, alpha is the only architecture that has the value of
the XTABS flag not equivalent to TAB3.

license
Many user space API headers are missing licensing information, which
makes it hard for compliance tools to determine the correct license.
By default are files without license information under the default
license of the kernel, which is GPLV2. Marking them GPLV2 would exclude
them from being included in non GPLV2 code, which is obviously not
intended. The user space API headers fall under the syscall exception
which is in the kernels COPYING file:
NOTE! This copyright does *not* cover user programs that use kernel
services by normal system calls - this is merely considered normal use
of the kernel, and does *not* fall under the heading of "derived work".
otherwise syscall usage would not be possible.
Update the files which contain no license information with an SPDX
license identifier. The chosen identifier is 'GPL-2.0 WITH
Linux-syscall-note' which is the officially assigned identifier for the
Linux syscall exception. SPDX license identifiers are a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne. See the previous patch in this series for the
methodology of how this patch was researched.
