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

bogus TIOCG/SSOFTCAR handling

char: riscom, fix rc_board indexing

2008-03-13T20:11:43+00:00

In riscom8_init_module, rc_board should be indexed by i, not by 0, otherwise
the loop is useless.

riscom8: Fix hang on load

2008-03-10T15:13:09+00:00

This has been around for a while but nobody reported it until recently.
Resubmitting the fix as it's appropriate for 2.6.25

Char: riscom8, remove wakeup and hangup bottomhalves

Both of them may be called directly from the code, don't add special code
and variables and schedule a work for them.

Char: riscom8, change rc_init_drivers prototype

2008-02-07T16:42:33+00:00

Let compiler decide if the rc_init_drivers function will be inlined and
mark it as __init, because it's called only from __init function.

riscom8: fix SMP brokenness

2008-02-06T18:41:00+00:00

After analyzing the elements that save_flags/cli/sti/restore_flags were
protecting, convert their usages to a global spinlock (the easiest and
most obvious next-step).  There were some usages of flags being
intentionally cached, because the code already knew the state of
interrupts.  These have been taken into account.

This allows us to remove CONFIG_BROKEN_ON_SMP.  Completely untested.
