2016-01-07workqueue: simplify the apply_workqueue_attrs_locked()wanghaibin
If the apply_wqattrs_prepare() returns NULL, it has already cleaned up the related resources, so it can return directly and avoid calling the clean up function again.

2016-01-07spi: sun4i: Prevent chip-select from being activated twice before a transferMarcus Weseloh
The SPI core calls set_cs before a transfer, but the SUN4I_CTL_CS_MANUAL flag is only set in transfer_one. This leads to the following pattern on the chip-select line (with runtime power-management on every transfer, without it only on the first one): activate, deactivate, activate, transfer, deactivate Moving the configuration of the SUN4I_CTL_CS_MANUAL flag from transfer_one to set_cs removes the double activation.

2016-01-07regulator: core: remove some dead codeDan Carpenter
Originally queue_delayed_work() used to negative error codes or 0 and 1 on success depending if the work was queued or not. It caused a lot of bugs where people treated all non-zero returns as failures so we changed it to return bool instead in d4283e937861 ('workqueue: make queueing functions return bool'). Now it never returns failure. Checking for negative values causes a static checker warning since it is impossible based on the bool type.

Commit 69fb4dcada77 ("power: Add an axp20x-usb-power driver") introduced a new driver for the USB power supply used on various Allwinner based SBCs. However, the driver was not added to multi_v7_defconfig which breaks USB support for some boards (e.g. LeMaker BananaPi) as the kernel will now turn off the USB power supply during boot by default if the driver isn't present. (This was not the case in linux 4.3 or lower where the USB power was always left on.) Hence, add the driver to multi_v7_defconfig in order to keep USB support working on those boards that require it.

Add IOCTL_GNTDEV_GRANT_COPY to allow applications to copy between user space buffers and grant references. This interface is similar to the GNTTABOP_copy hypercall ABI except the local buffers are provided using a virtual address (instead of a GFN and offset). To avoid userspace from having to page align its buffers the driver will use two or more ops if required. If the ioctl returns 0, the application must check the status of each segment with the segments status field. If the ioctl returns a -ve error code (EINVAL or EFAULT), the status of individual ops is undefined.

Lawrence reported that git clone could make system crash on a Qualcomm ARM soc based device (DragonBoard, 1G memory without swap) running 64bit Debian. It's turned out the crash is related with rx skb allocation failure. git could consume more than 600MB anonymous memory. And system is in extremely memory shortage case. But driver didn't handle the rx allocation failure case. This patch doesn't submit skb to upper layer if rx skb allocation fails. Instead, it reuse the old skb for rx DMA again. It's more like drop the packets if system is in memory shortage case. With this change, git clone is OOMed instead of system crash.

Moreover it can be powered off automatically whenever the last LPSS device goes down. In case of no power any access to the DMA controller will hang the system.

2016-01-07iommu/dma: Use correct offset in map_sgRobin Murphy
When mapping a non-page-aligned scatterlist entry, we copy the original offset to the output DMA address before aligning it to hand off to iommu_map_sg(), then later adding the IOVA page address portion to get the final mapped address. However, when the IOVA page size is smaller than the CPU page size, it is the offset within the IOVA page we want, not that within the CPU page, which can easily be larger than an IOVA page and thus result in an incorrect final address. Fix the bug by taking only the IOVA-aligned part of the offset as the basis of the DMA address, not the whole thing.

2016-01-07driver-core: platform: Add platform_irq_count()Stephen Boyd
A recent patch added calls to of_irq_count() in the qcom pinctrl drivers and that caused module build failures because of_irq_count() is not an exported symbol. We shouldn't export of_irq_count() to modules because it's an internal OF API that shouldn't be used by drivers. Platform drivers should use platform device APIs instead. Therefore, add a platform_irq_count() API that mirrors the of_irq_count() API so that platform drivers can stay DT agnostic.

2016-01-07rt2x00pci: Disable memory-write-invalidate when the driver exitsJia-Ju Bai
The driver calls pci_set_mwi to enable memory-write-invalidate when it is initialized, but does not call pci_clear_mwi when it is removed. Many other drivers calls pci_clear_mwi when pci_set_mwi is called, such as r8169, 8139cp and e1000. This patch adds pci_clear_mwi in error handling and removal procedure, which can fix the problem.

2016-01-07brcmfmac: introduce module parameter to force successful probeArend van Spriel
The module parameter can be used to ensure the probe succeeds thus claiming the device and allowing post-mortem debugging in case of firmware crash. It is only available when select CONFIG_BRCMDBG.

2016-01-07brcmfmac: Move all module parameters to one placeHante Meuleman
Module parameters are defined in several files. Move them in one place and make them device specific or global. This makes it easier to override device specific settings by external data like platform data in the future.
