2012-10-04drm/exynos: update crtc to plane safelyInki Dae
if old_crtc isn't same as encoder->crtc then it means that user changed crtc id to another one so a plane to old_crtc should be disabled so that current plane can be updated safely and plane->crtc should be set to new crtc(encoder->crtc) Signed-off-by: Inki Dae <inki.dae@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>
2012-10-04drm/exynos: check NV12M format specific to Exynos properlyInki Dae
this patch adds buf_cnt variable in exynos_drm_fb structure and that means a buffer count to drm framebuffer and also adds two functions to get/set the buffer count from/to exynos_drm_fb structure. if pixel format is not DRM_FORMAT_NV12MT then it gets a buffer count to drm framebuffer refering to mode_cmd->handles and offsets. but when booted, the buffer count will always be 1 because pixel format of console framebuffer is RGB format.

this patch fixes that when drm_crtc_helper_set_mode() is called, mode data for hardware overlay and conntroller are updated two times. for example, in case that drm_crtc_helper_set_mode() is called, overlay_ops->commit() and manager_ops->commit() callbacks can be called two times, first at drm_crtc_helper_set_mode() and second at drm_helper_connector_dpms().

2012-10-03firmware: teach the kernel to load firmware files directly from the filesystemLinus Torvalds
This is a first step in allowing people to by-pass udev for loading device firmware. Current versions of udev will deadlock (causing us to block for the 30 second timeout) under some circumstances if the firmware is loaded as part of the module initialization path, and this is causing problems for media drivers in particular. The current patch hardcodes the firmware path that udev uses by default, and will fall back to the legacy udev mode if the firmware cannot be found there. We'd like to add support for both configuring the paths and the fallback behaviour, but in the meantime this hopefully fixes the immediate problem, while also giving us a way forward.

2012-10-03mlx4_core: Adjust flow steering attach wrapper so that IB works on SR-IOV VFsJack Morgenstein
Currently, the InfiniBand stack does not support flow steering at the verbs level -- the only usage of flow steering in the IB driver is for L2 multicast attaches. We need to add the IB case to procedure mlx4_QP_FLOW_STEERING_ATTACH_wrapper() to allow IPoIB to work on VFs on ConnectX-3 when flow steering is enabled. Currently, the IB case in mlx4_QP_FLOW_STEERING_ATTACH_wrapper() is missing, so the procedure returns -EINVAL and IPoIB on VFs breaks.

2012-10-03bnx2x: fix ring size for 10G functionsYuval Mintz
Commit d760fc37b0f74502b3f748951f22c6683b079a8e caused 1G functions to allocate rx rings which were 1/10 of the size of 10G functions' rx rings. However, it also caused 10G functions on 5771x boards to allocate small rings, which limits their possible (default) rx throughput. This patch causes all 10G functions to use rings of intended length by default.

2012-10-03ceph: avoid 32-bit page index overflowAlex Elder
A pgoff_t is defined (by default) to have type (unsigned long). On architectures such as i686 that's a 32-bit type. The ceph address space code was attempting to produce 64 bit offsets by shifting a page's index by PAGE_CACHE_SHIFT, but the result was not what was desired because the shift occurred before the result got promoted to 64 bits. Fix this by converting all uses of page->index used in this way to use the page_offset() macro, which ensures the 64-bit result has the intended value.

2012-10-03kbuild: Fix gcc -x syntaxJean Delvare
The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax.
