2014-08-29drivers/rtc/rtc-s5m.c: re-add support for devices without irq specifiedBartlomiej Zolnierkiewicz
The rtc-s5m driver used to support devices without irq specified in the past. Re-add this support. The patch fixes boot for Insignal's Exynos4412 based Origen board.

2014-08-29zram: fix incorrect stat with failed_readsChao Yu
Since we allocate a temporary buffer in zram_bvec_read to handle partial page operations in commit 924bd88d703e ("Staging: zram: allow partial page operations"), our ->failed_reads value may be incorrect as we do not increase its value when failing to allocate the temporary buffer. Let's fix this issue and correct the annotation of failed_reads.

2014-08-28mfd: twl4030-power: Fix PM idle pin configuration to not conflict with ↵Tony Lindgren
regulators Commit 43fef47f94a1 (mfd: twl4030-power: Add a configuration to turn off oscillator during off-idle) added support for configuring the PMIC to cut off resources during deeper idle states to save power. This however caused regression for n900 display power that needed the PMIC configuration to be disabled with commit d937678ab625 (ARM: dts: Revert enabling of twl configuration for n900). Turns out the root cause of the problem is that we must use TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling regulators that may have been enabled before the init function for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the regulator framework control the regulators like it should. Here we need to only configure the sys_clken and sys_off_mode triggers for the regulators that cannot be done by the regulator framework as it's not running at that point. This allows us to enable the PMIC configuration for n900.

2014-08-28drm: fix division-by-zero on dumb_create()David Herrmann
Kinda unexpected, but DIV_ROUND_UP() can overflow if passed an argument bigger than UINT_MAX - DIVISOR. Fix this by testing for "!cpp" before using it in the following division. Note that DIV_ROUND_UP() is defined as: #define DIV_ROUND_UP(n,d) (((n) + (d) - 1) / (d)) ..this will obviously overflow if (n + d - 1) is bigger than UINT_MAX.

If we assign a Radeon device to a virtual machine, we can no longer assume a fixed hardware topology, like the GPU having a parent device. This patch simply adds a few pci_is_root_bus() tests to avoid passing a NULL pointer to PCI access functions, allowing the radeon driver to work in a QEMU 440FX machine with an assigned HD8570 on the emulated PCI root bus.

This avoids a problem seen with weston (for example) where the display gets stuck in "black screen" if starting weston first thing after boot. Possibly mdp5 needs something similar. The downstream android fbdev driver always requests DMA_E (or DMA_P) when display is active, rather than only enabling it on-demand as the drm driver does, which I believe has the same end result.

2014-08-26drm/msm: avoid flood of kernel logs on faultsRob Clark
87e956e9 changed the fault handler to return -ENOSYS, which causes the iommu driver to print out a huge splat. Which wouldn't be quite so bad if nothing ever faulted. But seems like some EXA composite operations generate quite a lot of (seemingly harmless) faults. That is probably a userspace problem, but the huge increase in verbosity from iommu fault dumps makes things kind of unusable. We probably should actually log *some* message (not conditional on drm.debug). But ratelimit it. Signed-off-by: Rob Clark <robdclark@gmail.com>

2014-08-22ibmveth: Fix endian issues with rx_no_buffer statisticAnton Blanchard
Hidden away in the last 8 bytes of the buffer_list page is a solitary statistic. It needs to be byte swapped or else ethtool -S will produce numbers that terrify the user. Since we do this in multiple places, create a helper function with a comment explaining what is going on.

2014-08-22net: xgene: fix possible NULL dereference in xgene_enet_free_desc_rings()Iyappan Subramanian
A NULL pointer dereference is possible for the argument ring->buf_pool which is passed to xgene_enet_free_desc_ring(), as ring could be NULL. And now since NULL pointers are being checked for before the calls to xgene_enet_free_desc_ring(), might as well take advantage of them and not call the function if the argument would be NULL.

2014-08-22net: fec: ptp: avoid register access when ipg clock is disabledNimrod Andy
The current kernel hang on i.MX6SX with rootfs mount from MMC. The root cause is that ptp uses a periodic timer to access enet register even if ipg clock is disabled. FEC ptp driver start one period timer to read 1588 counter register in the ptp init function that is called after FEC driver is probed. To save power, after FEC probe finish, FEC driver disable all clocks including ipg clock that is needed for register access. i.MX5x, i.MX6q/dl/sl FEC register access don't cause system hang when ipg clock is disabled, just return zero value. But for i.MX6sx SOC, it cause system hang. To avoid the issue, we need to check ptp clock status before ptp timer count access.

2014-08-21cxgb4: Free completed tx skbs promptlyHariprasad Shenai
Description of problem: The NIC card is not reporting back to the driver the transmitted skbs, so they get stuck in the TX ring causing issues with reference counters in other kernel components. Developed a new Automatic Egress Queue Update firmware facility to slowly tick through Egress Queues and send back any outstanding CIDX Updates which are laying around.

The next patch is contributed by Dan Carpenter, it fixes the error handling in the c_can's probe function.
