* tty: The big operations reworkAlan Cox2008-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Operations are now a shared const function block as with most other Linux objects - Introduce wrappers for some optional functions to get consistent behaviour - Wrap put_char which used to be patched by the tty layer - Document which functions are needed/optional - Make put_char report success/fail - Cache the driver->ops pointer in the tty as tty->ops - Remove various surplus lock calls we no longer need - Remove proc_write method as noted by Alexey Dobriyan - Introduce some missing sanity checks where certain driver/ldisc combinations would oops as they didn't check needed methods were present [akpm@linux-foundation.org: fix fs/compat_ioctl.c build] [akpm@linux-foundation.org: fix isicom] [akpm@linux-foundation.org: fix arch/ia64/hp/sim/simserial.c build] [akpm@linux-foundation.org: fix kgdb] Signed-off-by: Alan Cox <alan@redhat.com> Acked-by: Greg Kroah-Hartman <gregkh@suse.de> Cc: Jason Wessel <jason.wessel@windriver.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * Input: add PS/2 serio driver for AVR32 devicesHans-Christian Egtvedt2008-04-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the PSIF peripheral on AVR32 AP7 devices. It is implemented as a serio driver and will behave like a serio 8042 device. The driver has been tested with a Dell keyboard capable of running on 3.3 volts and a Logitech mouse on the STK1000 + STK1002 starter kit. The Logitech mouse was hacked by cutting the cord and using a bi-directional voltage converter to get the required 5 volt I/O level. For more information about the PSIF module, see the datasheet for AT32AP700X at http://www.atmel.com/dyn/products/datasheets.asp?family_id=682 Signed-off-by: Hans-Christian Egtvedt <hcegtvedt@atmel.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki2007-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | We need to take serio->drv_mutex in serio_cleanup() to prevent the function from being called while driver is in the middle of attaching to a serio port. Such situation can happen with i8042 and atkbd drivers if user rapidly presses Ctrl-Alt-Del during system startup, and leads to kernel oops.

| | | | | | | | | | | | | | | | | | | | This should get rid of "atkbd.c: Suprious NAK on isa0060/serio0" messages caused by broken MUX implementation. The box does not have external PS/2 ports and, according to documentation, automatically disables touchpad when an external mouse is plugged into a port replicator, so MUX mode would not work anyway.
