2006-07-19Input: implement new force feedback interfaceAnssi Hannula
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.

2006-07-06Input: introduce input_inject_event() functionDmitry Torokhov
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.

2006-07-06Input: add start() method to input handlersDmitry Torokhov
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>

2006-07-05[PATCH] powerpc: Fix loss of interrupts with MPICBenjamin Herrenschmidt
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.

2006-07-04[PATCH] fix AB-BA deadlock inversion at cs46xx_dsp_remove_scbArjan van de Ven
There is a code sequence where the locking is substream->self_group.lock -> ins->scbs[index].lock substream->self_group.lock is interrupt safe, and taken from irq context as well (trace is snipped for brevity) so what can happen is cpu 0 cpu 1 user context user context take ins->scbs[index].lock without disabling interrupts get substream->self_group.lock (irqsafe) try to get ins->scbs[index].lock (spins) interrupt happens try to get substream->self_group.lock (spins) which is an obvious AB-BA deadlock fix is to just take the lock with _irqsafe Signed-off-by: Arjan van de Ven <arjan@linux.intel.com> Cc: Jaroslav Kysela <perex@suse.cz> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2006-07-04[PATCH] mthca: initialize send and receive queue locks separatelyZach Brown
mthca: initialize send and receive queue locks separately lockdep identifies a lock by the call site of its initialization. By initializing the send and receive queue locks in mthca_wq_init() we confuse lockdep. It warns that that the ordered acquiry of both locks in mthca_modify_qp() is recursive acquiry of one lock: ============================================= [ INFO: possible recursive locking detected ] --------------------------------------------- modprobe/1192 is trying to acquire lock: (&wq->lock){....}, at: [<f892b4db>] mthca_modify_qp+0x60/0xa7b [ib_mthca] but task is already holding lock: (&wq->lock){....}, at: [<f892b4ce>] mthca_modify_qp+0x53/0xa7b [ib_mthca] Initializing the locks separately in mthca_alloc_qp_common() stops the warning and will let lockdep enforce proper ordering on paths that acquire both locks.

2006-07-04[PATCH] Fix copying of pgdat array on each node for ia64 memory hotplugYasunori Goto
I found a bug in memory hot-add code for ia64. IA64's code has copies of pgdat's array on each node to reduce memory access over crossing node. This array is used by NODE_DATA() macro. When new node is hot-added, this pgdat's array should be updated and copied on new node too. However, I used for_each_online_node() in scatter_node_data() to copy it. This meant its array is not copied on new node. Because initialization of structures for new node was halfway, so online_node_map couldn't be set at this time. To copy arrays on new node, I changed it to check value of pgdat_list[] which is source array of copies. I tested this patch with my Memory Hotadd emulation on Tiger4. This patch is for 2.6.17-git20.

2006-07-03[PATCH] Fix modular cpuid.koOGAWA Hirofumi
With recent change, if CONFIG_HOTPLUG_CPU is disabled, register_cpu_notifier() is not exported. And it breaked moduler msr/cpuid (msr.c was already fixed). We need to use register_hotcpu_notifier() now in module, instead of register_cpu_notifier().

2006-07-03[Bluetooth] Allow disabling of credit based flow controlMarcel Holtmann
This patch adds the module parameter disable_cfc which can be used to disable the credit based flow control. The credit based flow control was introduced with the Bluetooth 1.1 specification and devices can negotiate its support, but for testing purpose it is helpful to allow disabling of it.
