Lots of cleanups in here, no real new functionality this time around,
with the diffstat being that we removed more lines than we added!

Included in here are:

- termios unification cleanups from Al Viro, it's nice to finally get
this work done

- tty serial transmit cleanups in various drivers in preparation for
more cleanup and unification in future releases (that work was not
ready for this release)

- n_gsm fixes and updates

- ktermios cleanups and code reductions

- dt bindings json conversions and updates for new devices

- some serial driver updates for new devices

- lots of other tiny cleanups and janitorial stuff. Full details in
the shortlog.

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

kernel/panic: Drop unblank_screen call

console_unblank() does this too (called in both places right after),
and with a lot more confidence inspiring approach to locking.

Reconstructing this story is very strange:

In b61312d353da ("oops handling: ensure that any oops is flushed to
the mtdoops console") it is claimed that a printk(" "); flushed out
the console buffer, which was removed in e3e8a75d2acf ("[PATCH]
Extract and use wake_up_klogd()"). In todays kernels this is done way
earlier in console_flush_on_panic with some really nasty tricks. I
didn't bother to fully reconstruct this all, least because the call to
bust_spinlock(0); gets moved every few years, depending upon how the
wind blows (or well, who screamed loudest about the various issue each
call site caused).

Before that commit the only calls to console_unblank() where in s390
arch code.

The other side here is the console->unblank callback, which was
introduced in 2.1.31 for the vt driver. Which predates the
console_unblank() function by a lot, which was added (without users)
in 2.4.14.3. So pretty much impossible to guess at any motivation
here. Also afaict the vt driver is the only (and always was the only)
console driver implementing the unblank callback, so no idea why a
call to console_unblank() was added for the mtdooops driver - the
action actually flushing out the console buffers is done from
console_unlock() only.

Note that as prep for the s390 users the locking was adjusted in
2.5.22 (I couldn't figure out how to properly reference the BK commit
from the historical git trees) from a normal semaphore to a trylock.

Note that a copy of the direct unblank_screen() call was added to
panic() in c7c3f05e341a ("panic: avoid deadlocks in re-entrant console
drivers"), which partially inlined the bust_spinlocks(0); call.

Long story short, I have no idea why the direct call to unblank_screen
survived for so long (the infrastructure to do it properly existed for
years), nor why it wasn't removed when the console_unblank() call was
finally added. But it makes a ton more sense to finally do that than
not - it's just better encapsulation to go through the console
functions instead of doing a direct call, so let's dare. Plus it
really does not make much sense to call the only unblank
implementation there is twice, once without, and once with appropriate
locking.

s390: use common bust_spinlocks()

s390 is the only architecture that is using own bust_spinlocks()
variant, while other arch-s seem to be OK with the common
implementation.

Heiko Carstens [1] said

s390: use common bust_spinlocks()

s390 is the only architecture that is using own bust_spinlocks()
variant, while other arch-s seem to be OK with the common
implementation.

Heiko Carstens [1] said he would prefer s390 to use the common
bust_spinlocks() as well:
I did some code archaeology and this function is unchanged since ~17
years. When it was introduced it was close to identical to the x86
variant. All other architectures use the common code variant in the
meantime. So if we change this I'd prefer that we switch s390 to the
common code variant as well. Right now I can't see a reason for not
doing that

This patch removes s390 bust_spinlocks() and drops the weak attribute
from the common bust_spinlocks() version.
