2013-06-25net/tg3: Avoid delay during MMIO accessGavin Shan
When the EEH error is the result of a fenced host bridge, MMIO accesses can be very slow (milliseconds) to timeout and return all 1's, thus causing the driver various timeout loops to take way too long and trigger soft-lockup warnings (in addition to taking minutes to recover). It might be worthwhile to check if for any of these cases, ffffffff is a valid possible value, and if not, bail early since that means the HW is either gone or isolated. In the meantime, checking that the PCI channel is offline would be workaround of the problem.

2013-06-24sh_eth: fix misreporting of transmit abortSergei Shtylyov
Due to obviously missing braces, EESR.TABT (transmit abort) interrupt may be reported even if it hasn't happened, just when EESR.TWB (transmit descriptor write-back) interrupt happens. Luckily (?), EESR.TWB is disabled by the driver via the TRIMD register and all the interrupt masks, so that transmit abort is never actually logged...

2013-06-24sh_eth: fix unhandled RFE interruptSergei Shtylyov
EESR.RFE (receive FIFO overflow) interrupt is enabled by the driver on all SoCs and sh_eth_error() handles it but it's not present in any initializer/assignment of the 'eesr_err_check' field of 'struct sh_eth_cpu_data'. This leads to that interrupt not being handled and cleared, and finally to disabling IRQ and the driver being non-functional. Modify DEFAULT_EESR_ERR_CHECK macro and all explicit initializers of the above mentioned field to contain the EESR.RFE bit. Remove useless backslashes from the initializers, while at it.

git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless into wireless John W. Linville says: ==================== This will probably be the last batch of wireless fixes intended for 3.10. Many of these are one- or two-liners, and a couple of others are mostly relocating existing code to avoid races or to limit the code to effecting specific hardware, etc. The mac80211 fixes have a couple of exceptions to the above. Regarding those, Johannes says: "Following davem's complaint about my patch, here's a new pull request w/o the patch he was complaining about, but instead with the const fix rolled into the fix. I have a fix for radar detection, one for rate control and a workaround for broken HT APs which is a regression fix because we didn't rely on them to be correct before." Johannes also sends some iwlwifi fixes: "I picked up Nikolay's patch for the chain noise calibration bug that seems to have been there forever, a fix from Emmanuel for setting TX flags on BAR frames and a fix of my own to avoid printing request_module() errors if the kernel isn't even modular. We also have our own version of Stanislaw's fix for rate control." Along with those... Anderson Lizardo fixes a Bluetooth memory corruption bug when an MTU value is set to too small of a value. Arend van Spriel sends a revised brcmsmac bug that fixes a regression caused by a bad return value in an earlier patch. He also sends a brcmfmac fix to avoid an oops when loading the driver at boot. Daniel Drake fixes a race condition in btmrvl that causes hangs on suspend for OLPC hardware. Johan Hedberg adds a check to avoid sending a HCI_Delete_Stored_Link_Key command to devices that don't support them, avoiding some scary looking log spam. Stanislaw Gruszka gives us a fix for iwlegacy to be able to use rates higher than 1Mb/s on older wireless networks. He also sends an rt2x00 fix to reinstate older tx power handling behavior for some devices that didn't work well with the current code. ==================== Signed-off-by: David S.

2013-06-17alx: add a simple AR816x/AR817x device driverJohannes Berg
This is a very simple driver, based on the original vendor driver that Qualcomm/Atheros published/submitted previously, but reworked to make the code saner. However, it also lost a number of features (TSO/GSO, VLAN acceleration and multi- queue support) in the process, as well as debugging support features I didn't have any use for. The only thing I left is checksum offload. More features can obviously be added, but this seemed like a good start for having a driver in mainline at all. Johannes Stezenbach has verified that the driver works on AR8161, I have a AR8171 myself. The E2200 device ID I found on github in somebody's repository.

2013-06-13mei: init: Flush scheduled work before resetting the deviceSamuel Ortiz
Flushing pending work items before resetting the device makes more sense than doing so afterwards. Some of them, like e.g. the NFC initialization one, find themselves with client IDs changed after the reset, eventually leading to trigger a client.c:mei_me_cl_by_id() warning after a few modprobe/rmmod cycles.

2013-06-13of: Fix locking vs. interruptsBenjamin Herrenschmidt
The OF code uses irqsafe locks everywhere except in a handful of functions for no obvious reasons. Since the conversion from the old rwlocks, this now triggers lockdep warnings when used at interrupt time. At least one driver (ibmvscsi) seems to be doing that from softirq context. This converts the few non-irqsafe locks into irqsafe ones, making them consistent with the rest of the code.

2013-06-13Bluetooth: btmrvl: fix thread stopping raceDaniel Drake
There is currently a race condition in the btmrvl_remove_card() which is causing hangs on suspend for OLPC. When the race occurs, kthread_stop() never returns. The problem is that btmrvl_service_main_thread() calls kthread_should_stop() and then does a fair number of things before restarting the loop and sleeping. If the thread gets stopped after kthread_should_stop() is checked, but before the sleep happens, the thread will go to sleep and won't necessarily be woken up. Move the kthread_should_stop() check into a race-free place. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: John W.
