serial167: fix read buffer overflow

2009-10-01T23:11:16+00:00

Check whether index is within bounds before grabbing the element.

Also, since NR_PORTS is defined ARRAY_SIZE(cy_port), cy_port[NR_PORTS] is
out of bounds as well.

cleanup console_print()

2009-09-15T00:41:42+00:00

console_print() is an old legacy interface mostly unused in the entire
kernel tree. It's best to clean up its existing use and let developers
use their own implementation of it as they feel fit.

headers: smp_lock.h redux

2009-07-12T19:22:34+00:00

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Fix incorrect use of loose in tty/serial drivers

[Folded together as one diff from 3]

It should be 'lose', not 'loose'.

tty/serial: lay the foundations for the next set of reworks

2008-04-30T15:29:45+00:00

- Stop drivers calling their own flush method indirectly, it obfuscates code
  and it will change soon anyway

- A few more lock_kernel paths temporarily needed in some driver internal
  waiting code

- Remove private put_char method that does a write call for one char - we
  have that anyway

- Most but not yet all of the termios copy under lock fixing (some has other
  dependencies to follow)

- Note a few locking bugs in drivers found in the process

- Kill remaining [ab]users of TIOCG/SSOFTCAR in the driver, these must go to
  fix the termios locking

Char: serial167, remove bottomhalf

2008-02-07T16:42:34+00:00

- 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
