2013-10-15Revert "ARM: init: add support for reserved memory defined by device tree"Marek Szyprowski
This reverts commit 10bcdfb8ba24760f715f0a700c3812747eddddf5. There is no consensus on the bindings for the reserved memory, so the code for handing it will be reverted. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Grant Likely <grant.likely@linaro.org>
2013-10-15drm/i915: Kill fbc_wm_enabled from intel_wm_configVille Syrjälä
The fbc_wm_enabled member in intel_wm_config is useless for the time being. The original idea for it was that we'd pre-compute it and so that the WM merging process could know whether it needs to worry about FBC watermarks at all. But we don't have a convenient way to pre-check for the possibility of FBC being used. intel_update_fbc() should be split up for that.

Move the watermark max computations into haswell_update_wm(). This allows keeping the 1/2 vs. 5/6 split code in one place, and avoid having to pass around so many things. We also save a bit of stack space by only requiring one copy of struct hsw_wm_maximums. Also move the intel_wm_config out from hsw_compute_wm_parameters() and pass it it.

2013-10-15drm/i915: Add intel_pipe_wm and prepare for watermark pre-computeVille Syrjälä
Introduce a new struct intel_pipe_wm which contains all the watermarks for a single pipe. Use it to unify the LP0 and LP1+ watermark computations so that we can just iterate through the watermark levels neatly and call ilk_compute_wm_level() for each. Also add another tool ilk_wm_merge() that merges the LP1+ watermarks from all pipes. For that, embed one intel_pipe_wm inside intel_crtc that contains the currently valid watermarks for each pipe. This is mainly preparatory work for pre-computing the watermarks for each pipe and merging them at a later time. For now the merging still happens immediately. v2: Add some comments about level 0 DDB split and intel_wm_config Add WARN_ON for level 0 being disabled s/lp_wm/merged Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Paulo Zanoni <paulo.r.zanoni@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-10-14drm/i915: Fix scanoutpos calculationsVille Syrjälä
The reported scanout position must be relative to the end of vblank. Currently we manage to fumble that in a few ways. First we don't consider the case when vtotal != vbl_end. While that isn't very common (happens maybe only w/ old panel fitting hardware), we can fix it easily enough. The second issue is that on pre-CTG hardware we convert the pixel count to horizontal/vertical components at the very beginning, and then forget to adjust the horizontal component to be relative to vbl_end. So instead we should keep our numbers in the pixel count domain while we're adjusting the position to be relative to vbl_end. Then when we do the conversion in the end, both vertical _and_ horizontal components will come out correct. v2: Change position to int from u32 to avoid sign issues Cc: Mario Kleiner <mario.kleiner@tuebingen.mpg.de> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: mario.kleiner.de@gmail.com Tested-by: mario.kleiner.de@gmail.com Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2013-10-14Revert "of: Feed entire flattened device tree into the random pool"Grant Likely
This reverts commit 109b6236294b53d8eaa50be7d9e9ad37079f5f7e. Tim Bird expressed concern that this will have a bad effect on boot time, and while simple tests have shown it to be okay with simple tree, a device tree blob can potentially be quite large and add_device_randomness() is not a fast function. Rather than do this for all platforms unconditionally, I'm reverting this patch and would like to see it revisited. Instead of feeding the entire tree into the random pool, it would probably be appropriate to hash the tree and feed the hash result into the pool. There really isn't a lot of randomness in a device tree anyway. In the majority of cases only a handful of properties are going to be different between machines with the same baseboard.

2013-10-14of: fix unnecessary warning on missing /cpus nodeGrant Likely
Not all DT platforms have all the cpus collected under a /cpus node. That just happens to be a details of FDT, ePAPR and PowerPC platforms. Sparc does something different, but unfortunately the current code complains with a warning if /cpus isn't there. This became a problem with commit f86e4718, "driver/core cpu: initialize of_node in cpu's device structure", which caused the function to get called for all architectures. This commit is a temporary fix to fail silently if the cpus node isn't present. A proper fix will come later to allow arch code to provide a custom mechanism for decoding the CPU hwid if the 'reg' property isn't appropriate.

2013-10-14ALSA: hda - Fix inverted internal mic not indicated on some machinesDavid Henningsson
The create_bind_cap_vol_ctl does not create any control indicating that an inverted dmic is present. Therefore, create multiple capture volumes in this scenario, so we always have some indication that the internal mic is inverted. This happens on the Lenovo Ideapad U310 as well as the Lenovo Yoga 13 (both are based on the CX20590 codec), but the fix is generic and could be needed for other codecs/machines too. Thanks to Szymon Acedański for the pointer and a draft patch.

2013-10-14drm/i915: Add breadcrumbs for why the backlight is being setChris Wilson
At the moment we have 3 paths that lead to actually_set_backlight(), from modesetting, ACPI/OpRegion requests and our very own intel_backlight interface, and we have no way of distinguishing them in the debug log. So add a debug breadcrumb to explain the source of the backlight changes. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-10-14mac80211: fix crash if bitrate calculation goes wrongJohannes Berg
If a frame's timestamp is calculated, and the bitrate calculation goes wrong and returns zero, the system will attempt to divide by zero and crash. Catch this case and print the rate information that the driver reported when this happens.

2013-10-14wireless: radiotap: fix parsing buffer overrunJohannes Berg
When parsing an invalid radiotap header, the parser can overrun the buffer that is passed in because it doesn't correctly check 1) the minimum radiotap header size 2) the space for extended bitmaps The first issue doesn't affect any in-kernel user as they all check the minimum size before calling the radiotap function. The second issue could potentially affect the kernel if an skb is passed in that consists only of the radiotap header with a lot of extended bitmaps that extend past the SKB. In that case a read-only buffer overrun by at most 4 bytes is possible. Fix this by adding the appropriate checks to the parser.
