2012-11-22md/raid5: Make sure we clear R5_Discard when discard is finished.NeilBrown
commit 9e44476851e91c86c98eb92b9bc27fb801f89072 MD: raid5 avoid unnecessary zero page for trim change raid5 to clear R5_Discard when the complete request is handled rather than when submitting the per-device discard request. However it did not clear R5_Discard for the parity device. This means that if the stripe_head was reused before it expired from the cache, the setting would be wrong and a hang would result. Also if the R5_Uptodate bit happens to be set, R5_Discard again won't be cleared. But R5_Uptodate really should be clear at this point. So make sure R5_Discard is cleared in all cases, and clear R5_Uptodate when a 'discard' completes. Signed-off-by: NeilBrown <neilb@suse.de>
2012-11-22md/raid5: move resolving of reconstruct_state earlier inNeilBrown
stripe_handle. The chunk of code in stripe_handle which responds to a *_result value in reconstruct_state is really the completion of some processing that happened outside of handle_stripe (possibly asynchronously) and so should be one of the first things done in handle_stripe(). After the next patch it will be important that it happens before handle_stripe_clean_event(), as that will clear some dev->flags bit that this code tests. Signed-off-by: NeilBrown <neilb@suse.de>

2012-11-21ARM - OMAP: ads7846: fix pendown debounce settingIgor Grinberg
Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the pendown GPIO debounce time setting by the below sequence: gpio_request_one() gpio_set_debounce() gpio_free() It also revealed a bug in the OMAP GPIO handling code which prevented the GPIO debounce clock to be disabled and CORE transition to low power states. Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on free/reset) fixes the OMAP GPIO handling code by making sure that the GPIO debounce clock gets disabled if no GPIO is requested from current bank. While fixing the OMAP GPIO handling code (in the right way), the above commit makes the gpio_request->set_debounce->free sequence invalid as after freeing the GPIO, the debounce settings are lost. Fix the debounce settings by moving the debounce initialization to the actual GPIO requesting code - the ads7846 driver.

Regarding the iwlwifi tree, Johannes says: "Please also pull my iwlwifi.git tree, I have two fixes: one to remove a spurious warning that can actually trigger in legitimate situations, and the other to fix a regression from when monitor mode was changed to use the "sniffer" firmware mode."

On top of that, a few more bits... Albert Pool adds a USB ID to rtlwifi.

This is a regression introduced by ceb90fa0 (xen/privcmd: add PRIVCMD_MMAPBATCH_V2 ioctl). It broke xentrace as it used xc_map_foreign() instead of xc_map_foreign_bulk(). Most code-paths prefer the MMAPBATCH_V2, so this wasn't very obvious that it broke. The return value is set early on to -EINVAL, and if all goes well, the "set top bits of the MFN's" never gets called, so the return value is still EINVAL when the function gets to the end, causing the caller to think it went wrong (which it didn't!)

2012-11-21ASoC: kirkwood-i2s: more pause-mode fixesRussell King
Don't even momentarily set the pause status when starting the channel; if we do, we should check the busy bit to ensure that we comply with the spec.

2012-11-21ASoC: kirkwood-i2s: fix DMA underrunsRussell King
Stress testing the driver with multiple start/stop events causes kirkwood-dma to report underrun errors (which used to cause the kernel to lock up solidly). This is because kirkwood-i2s is not respecting the restrictions imposed on clearing the 'pause' bit. Follow what the spec says; the busy bit must be read as being clear twice before the pause bit can be released. This solves the underruns. However, it has been noticed that the busy bit occasionally does not clear itself, hence the waiting is bounded to 5ms maximum to avoid a new reason for the kernel to lockup.

This is especially important on Dove platforms as errors are handled separately, and allows us to clear down the real cause of the interrupt.

2012-11-19of/net/mdio-gpio: Fix pdev->id issue when using devicetrees.Srinivas Kandagatla
When the mdio-gpio driver is probed via device trees, the platform device id is set as -1, However the pdev->id is re-used as bus-id for while creating mdio gpio bus. So For device tree case the mdio-gpio bus name appears as "gpio-ffffffff" where as for non-device tree case the bus name appears as "gpio-<bus-num>" Which means the bus_id is fixed in device tree case, so we can't have two mdio gpio buses via device trees. Assigning a logical bus number via device tree solves the problem and the bus name is much consistent with non-device tree bus name. Without this patch 1. we can't support two mdio-gpio buses via device trees. 2. we should always pass gpio-ffffffff as bus name to phy_connect, very different to non-device tree bus name. So, setting up the bus_id via aliases from device tree is the right solution and other drivers do similar thing.
