2014-09-24gpio: Fix potential NULL handler data in chained irqchip handlerJarkko Nikula
There is possibility with misconfigured pins that interrupt occurs instantly after setting irq_set_chained_handler() in gpiochip_set_chained_irqchip(). Now if handler gets called before irq_set_handler_data() the handler gets NULL handler data.

If et131x_rx_dma_memory_alloc() allocates rx_ring->fbr[0] but fails to allocate rx_ring->fbr[1], this leaves fbr[0]->ring_virtaddr with the possibility of being accessed in et131x_rx_dma_memory_free() as it contains a random value, potentially causing an oops. Fix this by zeroing the fbr memory on allocation. Subsequent frees of this fbr memory explicitly zeros the ring_virtaddr value.

2014-09-23imx-drm: imx-drm-core: add basic suspend/resume supportShawn Guo
HDMI currently stops working after a system suspend/resume cycle. The cause is that the mode setting states in hardware gets lost and isn't restored across the suspend/resume cycle. The patch adds a very basic suspend/resume support to imx-drm driver, and calls drm_helper_resume_force_mode() in .resume hook to restore the mode setting states, so that HDMI can continue working after a system suspend/resume cycle. Since the suspend/resume hook can be called with drm_device pointer being NULL from driver data, we need a check on the pointer in the hooks. And to avoid using a stale pointer from driver data, it also clears driver data in .unload hook.

2014-09-23imx-drm: ipuv3-plane: remove function ipu_plane_dpms()Shawn Guo
All those ipu_*_put() calls in ipu_plane_dpms() are unnecessary, because the only occurrence of ipu_plane_dpms() with 'mode' not being DRM_MODE_DPMS_ON is in function ipu_disable_plane(), which already has a ipu_plane_put_resources() call to put those ipu resources right after ipu_plane_dpms(). So with those redundant ipu_*_put() calls removed from ipu_plane_dpms(), the only left code in the function is ipu_plane_enable|disable(). Thus, we can just call ipu_plane_enable|disable() as needed directly and remove the ipu_plane_dpms() function completely.

2014-09-23Drivers: hv: vmbus: Enable interrupt driven flow controlK. Y. Srinivasan
In win8 we have a feature that allows for interrupt driven flow management for host/guest communication. For instance, if the host were blocked because there was no space available in the ringbuffer, the host could request that the guest send an interrupt when space becomes available in the ringbuffer (when the guest drains the ringbuffer). While this feature was implemented in the guest a while ago, we had not advertised that the guest supported this feature. This patch advertises the support to the host. For pre-win8 hosts, this has no effect since the size of the ringbuffer control structure has not changed and all changes have been backward compatible - unused/reserved space has been used to implement this feature. In this version of the patch I have cleaned up the commit log based on feedback from Greg KH. Signed-off-by: K. Y.

2014-09-23Drivers: hv: vmbus: Cleanup hv_post_message()K. Y. Srinivasan
Minimize failures in this function by pre-allocating the buffer for posting messages. The hypercall for posting the message can fail for a number of reasons: 1. Transient resource related issues 2. Buffer alignment 3. Buffer cannot span a page boundry We address issues 2 and 3 by preallocating a per-cpu page for the buffer. Transient resource related failures are handled by retrying by the callers of this function. This patch is based on the investigation done by Dexuan Cui <decui@microsoft.com>.
