3099bbc594 Char: serial167, remove bottomhalf
- Cy_EVENT_OPEN_WAKEUP is simple wake_up
- Cy_EVENT_HANGUP is wake_up + tty_hangup, which schedules its own work
- Cy_EVENT_WRITE_WAKEUP is tty_wakeup which may be called directly too

There is no need to schedule a bottomhalf for either of them. One is fast

a96ca105a6 mga_dma: return 'err' not just zero from mga_do_cleanup_dma()
While reading some code I stumbled across the use of 'err' in
drivers/char/drm/mga_dma.c::mga_do_cleanup_dma() and I think there's a small
problem.

The variable is only used inside #if __OS_HAS_AGP which is fine, but all that
ever happens is an assignment to the variable - it is never actually used for
anything.  The variable is nicely initialized to zero which is also what the
return statement at the end of function returns (always at the moment).

It looks to me like that function should be returning 'err' instead of always
just returning 0.  Here's a patch to do that.

54d2a37eda Fix IXANY and restart after signal (e.g. ctrl-C) in n_tty line discipline
Fix two N_TTY line discipline issues related to resuming a stopped TTY
(typically done with ctrl-S):

1) Fix handling of character that resumes a stopped TTY (with IXANY)

With "stty ixany", the TTY line discipline would lose the first character
after the stop, so typing, for example, "hi^Sthere" resulted in "hihere"
(the 't' would cause the resume after ^S, but it would then be thrown away
rather than processed as an input character).  This was inconsistent with
the behavior of other Unix systems.

2) Fix interrupt signal (e.g. ctrl-C) behavior in stopped TTYs

With "stty -ixany" (often the default), interrupt signals were ignored
in a stopped TTY until the TTY was resumed with the start char (typically
ctrl-Q), which was inconsistent with the behavior of other Unix systems.

ec5b1157f8 tty: enable the echoing of ^C in the N_TTY discipline
Turn on INTR/QUIT/SUSP echoing in the N_TTY line discipline (e.g.  ctrl-C
will appear as "^C" if stty echoctl is set and ctrl-C is set as INTR).

Linux seems to be the only unix-like OS (recently I've verified this on
Solaris, BSD, and Mac OS X) that does *not* behave this way, and I really
miss this as a good visual confirmation of the interrupt of a program in
the console or xterm.  I remember this fondly from many Unixs I've used
over the years as well.  Bringing this to Linux also seems like a good way
to make it yet more compliant with standard unix-like behavior.
