2011-01-20cxgb4: fix reported state of interfaces without linkDimitris Michailidis
Currently tools like ip and ifconfig report incorrect state for cxgb4 interfaces that are up but do not have link and do so until first link establishment. This is because the initial netif_carrier_off call is before register_netdev and it needs to be after to be fully effective. Fix this by moving netif_carrier_off into .ndo_open.

2011-01-20Fix broken "pipe: use event aware wakeups" optimizationLinus Torvalds
Commit e462c448fdc8 ("pipe: use event aware wakeups") optimized the pipe event wakeup calls to avoid wakeups if the events do not match the requested set. However, the optimization was buggy, in that it didn't actually use the correct sets for the events: when we make room for more data to be written, the pipe poll() routine will return both the POLLOUT _and_ POLLWRNORM bits. Similarly for read. And most critically, when a pipe is released, that will potentially result in POLLHUP|POLLERR (depending on whether it was the last reader or writer), not just the regular POLLIN|POLLOUT. This bug showed itself as a hung gnome-screensaver-dialog process, stuck forever (or at least until it was poked by a signal or by being traced) in a poll() system call.

2011-01-20i915: Fix i915 suspend delayLinus Torvalds
During system suspend, the "wait for ring buffer to empty" loop would always time out after three seconds, because the faster cached ring buffer head read would always return zero. Force the slow-and-careful PIO read on all but the first iterations of the loop to fix it. This also removes the unused (and useless) 'actual_head' variable that tried to approximate doing this, but did it incorrectly. Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Rafael J.

2011-01-20staging: usbip: vhci: handle EAGAIN from SO_RCVTIMEOMax Vozeler
If there is a receive timeout without any active requests, we can tell the connection was idle and ignore the timeout. If there are active requests for which we expect to receive a reply we close the connection. This makes it possible to set an upper bound on the time a usbip device may be unresponsive. This is a workaround for the lack of heart-beat messages in the USBIP protocol. Extending the protocol would break compatibility with all previous stub versions, so this seems like the lesser evil.

Regression since commit 10389536742c, "firewire: core: check for 1394a compliant IRM, fix inaccessibility of Sony camcorder": The camcorder Canon MV5i generates lots of bus resets when asynchronous requests are sent to it (e.g. Config ROM read requests or FCP Command write requests) if the camcorder is not root node. This causes drop- outs in videos or makes the camcorder entirely inaccessible. https://bugzilla.redhat.com/show_bug.cgi?id=633260 Fix this by allowing any Canon device, even if it is a pre-1394a IRM like MV5i are, to remain root node (if it is at least Cycle Master capable). With the FireWire controller cards that I tested, MV5i always becomes root node when plugged in and left to its own devices.

It's possible that when we access the ByteCount that the alignment will be off. Most CPUs deal with that transparently, but there's usually some performance impact. Some CPUs raise an exception on unaligned accesses. Fix this by accessing the byte count using the get_unaligned and put_unaligned inlined functions.

2011-01-20ACPI / Battery: remove battery refresh on resumeLinus Torvalds
This partially reverts commit da8aeb92d4853f37e281f11fddf61f9c7d84c3cd ("ACPI / Battery: Update information on info notification and resume"), which causes a hang on resume on at least some machines. This bug was bisected on an ASUS EeePC 901, which hangs at resume time if we do that "acpi_battery_refresh(battery)" in the battery resume function. Rafael suspects we'll still need to refresh the sysfs files upon resume, but that that can be done from a PM notifier (that will run after thawing user space).

Lately, mailbox callbacks have been replaced by notifier block call chains, this needs to be changed in the users of mailbox, otherwise compilation will break due to missing parameters. For this new change to work, io_mbox_msg needs to be compatible with the notifier_call definition.

2011-01-20staging: comedi: ni_labpc: Use shared IRQ for PCMCIA cardIan Abbott
The ni_labpc driver module only requests a shared IRQ for PCI devices, requesting a non-shared IRQ for non-PCI devices. As this module is also used by the ni_labpc_cs module for certain National Instruments PCMCIA cards, it also needs to request a shared IRQ for PCMCIA devices, otherwise you get a IRQ mismatch with the CardBus controller.

2011-01-20staging: tidspbridge: configure full L1 MMU rangeGuzman Lugo, Fernando
IVA MMU can manage up to 4GB of address space through its page tables, given that it's L1 is divided into 1MB sections it requires at least 16KB for its table which represents 4096 entries of 32 bits each. Previously, only 1GB was being handled by setting the page table size to 4KB, any virtual address beyond of the L1 size used, would fall into memory that does not belong to L1 translation tables, leading to unpredictable results. So, set the L1 table size to cover the entire MMU range (4GB) whether is meant to be used or not.

The original code called input_free_device(rmi4_data->input_dev) after input_unregister_device(rmi4_data->input_dev) and that's a double free. This is described in the comments to input_unregister_device(). The normal way to handle this is to make input_register_device() the last function in the probe which can fail.

2011-01-20staging: hv: Removed unneeded call to netif_stop_queue() in hv_netvscHank Janssen
Removed the call to netif_stop_queue() in netvsc_probe() as the queue is not initialized at that point and further call to it after queue initialization is really not necessary. This change was prompted after an upstream change went into 2.6.37 (netif_tx_stop_queue) that now checks if netif_stop_queue is called before register with netdev is done. This will eliminate the warning message to the log when hv_netvsc driver starts up.
