This patch allows the rndis_wlan driver to connect to TKIP PSK networks. It uses the ASSOCIATION_INFORMATION RNDIS call to pull back the IEs and sends them back to userspace using wireless events. Tested on a few wireless networks I have access to. Based on the similar code in ndiswrapper.

2008-05-28rt2x00: Don't count retries as failureIvo van Doorn
Link quality estimation became quite low for all rt2x00 drivers because the number of retries it took to send the frame were counted as failure.

2008-05-27pciehp: move msleep after power offKenji Kaneshige
According to the PCI Express specification, we must wait for at least 1 second after turning power off before taking any action that relies on power having been removed from the slot/adapter. For this, current pciehp wait for 1 second after issuing the power off command in hpc_power_off_slot() function. But waiting for 1 second in hpc_power_off_slot() can make pciehp probing slow-down because pciehp probe code calls hpc_power_off_slot() if the slot is not occupied just in case. We don't need to wait for 1 second at the pciehp probe time because there is no action on that empty slot. So move 1 second wait from hpc_power_off_slot() to the caller of hpc_power_off_slot().

2008-05-27pciehp: poll cmd completion if hotplug interrupt is disabledKenji Kaneshige
Fix improper long wait for command completion in pciehp probing. As described in PCI Express specification, software notification is not generated if the command that occurs as a result of a write to the Slot Control register that disables software notification of command completed events. Since pciehp driver doesn't take it into account, such command is issued in pciehp probing, and it causes improper long wait for command completion. This patch changes the pciehp driver to take such command into account.

2008-05-27pciehp: fix slow probingKenji Kaneshige
Fix the "pciehp probing slow" problem reported from Jan C. Nordholz in http://bugzilla.kernel.org/show_bug.cgi?id=10751. The command completed bit in Slot Status register applies only to commands issued to control the attention indicator, power indicator, power controller, or electromechanical interlock. However, writes to other parts of the Slot Control register would end up writing to the control fields. Hence, any write to Slot Control register is considered as a command. However, if the controller doesn't support any of attention indicator, power indicator, power controller and electromechanical interlock, command completed bit would not set in writing to Slot Control register. In this case, we should not wait for command completed bit set, otherwise all commands would be considered not completed in timeout seconds (1 sec.). The cause of the problem is pciehp driver didn't take this situation into account. This patch changes pciehp to take it into account. This patch also add the check for "No Command Completed Support" bit in Slot Capability register. If it is set, we should not wait for command completed bit set as well. This problem seems to be revealed by the commit c27fb883dffe11aa4cb35ecea1fa1832ba45d4da that fixed the bug that pciehp did not wait for command completed properly (pciehp just ignored the command completion event).

2008-05-27[SCSI] fusion mpt: fix target missing after resetting external raidMichael Reed
Following a hard reset of a SAS raid, one of the raid targets is occasionally missing. I tracked this down to a pretty obscure little bug. The LSI fusion drivers for SAS and Fibre Channel both use their respective transport layers. Those transport layers increment the target number assigned to new targets. The routine __scsi_scan_target uses the "this_id" element of the Scsi_Host structure to avoid scanning the scsi host adapter. Both fusion drivers set "this_id" from a value returned in a firmware PortFacts response. For my particular test case (SAS) the firmware id assigned to the initiator was 173. After enough raid resets to cause the raid targets to go and come a sufficient number of times, the id assigned by the transport to a raid target would match the id assigned by the host adapter to the "this_id" field, resulting in that target not being scanned. Fix by not assigning this_id and not checking it in slave_configure.

2008-05-26IB/ipath: Avoid test_bit() on u64 SDMA status valueRoland Dreier
Gabriel C <nix.or.die@googlemail.com> pointed out that when the x86 bitops are updated to operate on unsigned long, the code in sdma_abort_task() will produce warnings: drivers/infiniband/hw/ipath/ipath_sdma.c: In function 'sdma_abort_task': drivers/infiniband/hw/ipath/ipath_sdma.c:267: warning: passing argument 2 of 'constant_test_bit' from incompatible pointer type and so on, because it uses test_bit() to operation on a u64 value (returned by ipath_read_kref64() for a hardware register). Fix up these warnings by converting the test_bit() operations to &ing with appropriate symbolic defines of the bits within the hardware register. This has the benign side-effect of making the code more self-documenting as well. Signed-off-by: Roland Dreier <rolandd@cisco.com>

2008-05-26tuner: Do not alter i2c_client.nameMichael Krufky
The tuner driver used to change i2c_client.name for its own needs, but it really shouldn't, as this field is used by i2c-core to do the device/driver matching. So, create and use a separate field for the tuner driver needs. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2008-05-25[WATCHDOG] Fix booke_wdt.c on MPC85xx SMP system'sChen Gong
On Book-E SMP systems each core has its own private watchdog. If only one watchdog is enabled, when the core that doesn't enable the watchdog is hung, system can't reset because no watchdog is running on it. That's bad. It means we must enable watchdogs on both cores. We can use smp_call_function() to send appropriate messages to all the other cores to enable and update the watchdog.

2008-05-24spi: remove some spidev oops-on-rmmod pathsDavid Brownell
Somehow the spidev code forgot to include a critical mechanism: when the underlying device is removed (e.g. spi_master rmmod), open file descriptors must be prevented from issuing new I/O requests to that device. On penalty of the oopsing reported by Sebastian Siewior <bigeasy@tglx.de> ... This is a partial fix, adding handshaking between the lower level (SPI messaging) and the file operations using the spi_dev. (It also fixes an issue where reads and writes didn't return the number of bytes sent or received.) There's still a refcounting issue to be addressed (separately).
