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.

Char: riscom8, remove wakeup and hangup bottomhalves

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

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.

drivers/char/riscom8: clean up irq handling

2007-10-23T23:53:17+00:00

Make irq handling more efficient, by passing board pointer via
request_irq() to our irq handler's dev_id argument.

This eliminates a table lookup upon each interrupt, and eliminates an
associated global variable (the table).

[PATCH] tty: switch to ktermios

2006-12-08T16:28:57+00:00

This is the grungy swap all the occurrences in the right places patch that
goes with the updates.  At this point we have the same functionality as
before (except that sgttyb() returns speeds not zero) and are ready to
begin turning new stuff on providing nobody reports lots of bugs

If you are a tty driver author converting an out of tree driver the only
impact should be termios->ktermios name changes for the speed/property
setting functions from your upper layers.

If you are implementing your own TCGETS function before then your driver
was broken already and its about to get a whole lot more painful for you so
please fix it 8)

Also fill in c_ispeed/ospeed on init for most devices, although the current
code will do this for you anyway but I'd like eventually to lose that extra
paranoia
