* Input: implement new force feedback interfaceAnssi Hannula2006-07-19
| | | | | | | | | | | | | | | | | Implement a new force feedback interface, in which all non-driver-specific operations are separated to a common module. This includes handling effect type validations, locking, etc. The effects are now file descriptor specific instead of the previous strange half-process half-fd specific behaviour. The effect memory of devices is not emptied if the root user opens and closes the device while another user is using effects. This is a minor change and most likely no force feedback aware programs are affected by this negatively. Otherwise the userspace interface is left unaltered.

| | | | | | | | | | Although the Spaceball 4000FLX Lefty is already supported by the spaceball driver, it does not register properly due to SPACEBALL_MAX_ID being set too low.

* Input: introduce input_inject_event() functionDmitry Torokhov2006-07-06
| | | | | | | | | | Create input_inject_event() function which is to be used by input handlers as opposed to input_event() which is reserved for drivers implementing input devices. The difference is that if device is "grabbed" by some process input_inject_event() will ignore events unless sent from the handle that is currently owns the device.

* Input: add start() method to input handlersDmitry Torokhov2006-07-06
| | | | | | | | | The new start() method is called immediately after connect() and also when "grabbed" device is released by its owner. This will allow input handlers to re-synchronize state of once-grabbed device with the rest of devices. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

* [PATCH] powerpc: Fix loss of interrupts with MPICBenjamin Herrenschmidt2006-07-05
| | | | | | | | | | | | | | | | | | | With the new interrupt rework, an interrupt "host" map() callback can be called after the interrupt is already active. It's called again for an already mapped interrupt to allow changing the trigger setup, and currently this is not guarded with a test of wether the interrupt is requested or not. I plan to change some of this logic to be a bit less lenient against random reconfiguring of live interrupts but just not yet. The ported MPIC driver has a bug where when that happens, it will mask the interrupt. This changes it to preserve the previous masking of the interrupt instead.
