2012-11-20xen/privcmd: Correctly return success from IOCTL_PRIVCMD_MMAPBATCHMats Petersson
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!) Now also including Andres "move the ret = -EINVAL into the error handling path, as this avoids other similar errors in future.

2012-11-21Merge remote-tracking branch 'agust/merge' into mergeBenjamin Herrenschmidt
Anatolij 52xx updates: Patch for pcm030 device tree fixing the probe() in pcm030-audio-fabric driver. Changes to this driver have been merged in 3.7-rc1 via ASoC tree, but this required device tree patch was submitted separately to the linux-ppc list and is still missing in mainline. Without this patch the probe() in pcm030-audio-fabric driver wrongly returns -ENODEV. A patch from Wolfram fixing wrong invalid critical irq warnings for all mpc5200 boards. Another patch for all mpc5200 device trees fixing wrong L1 cell in the LPB FIFO interrupt property and moving the LPB FIFO node to the common mpc5200b.dtsi file so that this common node will be present in all mpc5200 device trees.
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. In any case, it isn't necessary; we will not active on a START event so there is no need to pause the DMA.

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.

2012-11-21ASoC: kirkwood-dma: don't ignore other irq causes on errorRussell King
Ignoring the real cause of the interrupt is not a good idea; this behaviour has been observed to bring Dove platforms to silently lockup. Instead, on error fall through to the normal interrupt processing. This is especially important on Dove platforms as errors are handled separately, and allows us to clear down the real cause of the interrupt.

2012-11-21ACPI / platform: Initialize ACPI handles of platform devices in advanceRafael J. Wysocki
The current platform device creation and registration code in acpi_create_platform_device() is quite convoluted. This function takes an ACPI device node as an argument and eventually calls platform_device_register_resndata() to create and register a platform device object on the basis of the information contained in that code. However, it doesn't associate the new platform device with the ACPI node directly, but instead it relies on acpi_platform_notify(), called from within device_add(), to find that ACPI node again with the help of acpi_platform_find_device() and acpi_platform_match() and then attach the new platform device to it. This causes an additional ACPI namespace walk to happen and is clearly suboptimal. Use the observation that it is now possible to initialize the ACPI handle of a device before calling device_add() for it to make this code more straightforward. Namely, add a new field to struct platform_device_info allowing us to pass the ACPI handle of interest to platform_device_register_full(), which will then use it to initialize the new device's ACPI handle before registering it. This will cause acpi_platform_notify() to use the ACPI handle from the device structure directly instead of using the .find_device() routine provided by the device's bus type. In consequence, acpi_platform_bus, acpi_platform_find_device(), and acpi_platform_match() are not necessary any more, so remove them. Signed-off-by: Rafael J.

2012-11-21ACPI / driver core: Introduce struct acpi_dev_node and related macrosRafael J. Wysocki
To avoid adding an ACPI handle pointer to struct device on architectures that don't use ACPI, or generally when CONFIG_ACPI is not set, in which cases that pointer is useless, define struct acpi_dev_node that will contain the handle pointer if CONFIG_ACPI is set and will be empty otherwise and use it to represent the ACPI device node field in struct device. In addition to that define macros for reading and setting the ACPI handle of a device that don't generate code when CONFIG_ACPI is unset. Modify the ACPI subsystem to use those macros instead of referring to the given device's ACPI handle directly. Signed-off-by: Rafael J.

2012-11-21ACPI: Allow ACPI handles of devices to be initialized in advanceRafael J. Wysocki
Currently, the ACPI handles of devices are initialized from within device_add(), by acpi_bind_one() called from acpi_platform_notify() which first uses the .find_device() routine provided by the device's bus type to find the matching device node in the ACPI namespace. This is a source of some computational overhead and, moreover, the correctness of the result depends on the implementation of .find_device() which is known to fail occasionally for some bus types (e.g. PCI). In some cases, however, the corresponding ACPI device node is known already before calling device_add() for the given struct device object and the whole .find_device() dance in acpi_platform_notify() is then simply unnecessary. For this reason, make it possible to initialize the ACPI handles of devices before calling device_add() for them. Modify acpi_platform_notify() to call acpi_bind_one() in advance to check the device's existing ACPI handle and skip the .find_device() search if that is successful. Change acpi_bind_one() accordingly. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by: Mika Westerberg <mika.westerberg@linux.intel.com>

devm_* functions are device managed functions and make cleanup code simpler and smaller. devm_kzalloc and devm_regulator_get functions are used. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> [renamed the patch title by MyungJoo Ham] Signed-off-by: MyungJoo Ham <myungjoo.ham@samsung.com>
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.

2012-11-20md: make sure everything is freed when dm-raid stops an array.NeilBrown
md_stop() would stop an array, but not free various attached data structures. For internal arrays, these are freed later in do_md_stop() or mddev_put(), but they don't apply for dm-raid arrays. So get md_stop() to free them, and only all it from dm-raid. For internal arrays we now call __md_stop. Reported-by: majianpeng <majianpeng@gmail.com> Signed-off-by: NeilBrown <neilb@suse.de>
2012-11-20md: Avoid write invalid address if read_seqretry returned true.majianpeng
If read_seqretry returned true and bbp was changed, it will write invalid address which can cause some serious problem. This bug was introduced by commit v3.0-rc7-130-g2699b67. So fix is suitable for 3.0.y thru 3.6.y.
