2012-08-16drivers-core: make structured logging play nice with dynamic-debugJim Cromie
commit c4e00daaa96d3a0786f1f4fe6456281c60ef9a16 changed __dev_printk in a way that broke dynamic-debug's ability to control the dynamic prefix of dev_dbg(dev,..), but not dev_dbg(NULL,..) or pr_debug(..), which is why it wasnt noticed sooner. When dev==NULL, __dev_printk() just calls printk(), which just works. But otherwise, it assumed that level was always a string like "<L>" and just plucked out the 'L', ignoring the rest. However, dynamic_emit_prefix() adds "[tid] module:func:line:" to the string, those additions all got lost.

2012-08-16USB: qcserial: fix port handling on Gobi 1K and 2K+Dan Williams
Bjorn's latest patchset does break Gobi 1K and 2K because on both devices as it claims usb interface 0. That's because usbif 0 is not handled in the switch statement, and thus the if0 gets claimed when it should not. So let's just make things even simpler yet, and handle both the 1K and 2K+ cases separately. This patch should not affect the new Sierra device support, because those devices are matched via interface-specific matching and thus should never hit the composite code.

2012-08-16IB/mlx4: Check iboe netdev pointer before dereferencing itKleber Sacilotto de Souza
Unlike other parts of the mlx4_ib code, the function build_mlx_header() doesn't check if the iboe netdev of the given port is valid before dereferencing it, which can cause a crash if the ethernet interface has already been taken down.

2012-08-15mlx4_core: Fix integer overflow issues around MTT tableYishai Hadas
Fix some issues around int variables used in data structures related to memory registration. Handle int overflow in mlx4_init_icm_table by using a u64 intermediate variable and changing struct mlx4_icm_table num_obj field to be u32. Change some more fields/variables to use u32 instead of int to prevent a case where the variable becomes negative when bit 31 is set. Also subtract log_mtts_per_seg from the exponent when computing num_mtt, since its added later on in that very same code area. This and the previous commit fixes some issues which actually prevent commit db5a7a65c058 ("mlx4_core: Scale size of MTT table with system RAM") from working. Now, when the number of MTTs is scaled with the size of the RAM we can map up to 8TB.

2012-08-15mlx4_core: Allow large mlx4_buddy bitmapsYishai Hadas
mlx4_buddy_init uses kmalloc() to allocate bitmaps, which fails when the required size is beyond the max supported value (or when memory is too fragmented to handle a huge allocation). Extend this to use use vmalloc() if kmalloc() fails, and take that into account when freeing the bitmaps as well. This fixes a driver load failure when log num mtt is 26 or higher, and is a step in the direction of allowing to register huge amounts of memory on large memory systems.

2012-08-14drm/i915: reorder edp disabling to fix ivb MacBook AirDaniel Vetter
eDP is tons of fun. It turns out that at least the new MacBook Air 5,1 model absolutely doesn't like the new force vdd dance we've introduced in commit 6cb49835da0426f69a2931bc2a0a8156344b0e41 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Sun May 20 17:14:50 2012 +0200 drm/i915: enable vdd when switching off the eDP panel But that patch also tried to fix some neat edp sequence issue with the force_vdd timings. Closer inspection reveals that we've raised force_vdd only to do the aux channel communication dp_sink_dpms. If we move the edp_panel_off below that, we don't need any force_vdd for the disable sequence, which makes the Air happy. Unfortunately the reporter of the original bug that the above commit fixed is travelling, so we can't test whether this regresses things. But my theory is that since we don't check for any power-off -> force_vdd-on delays in edp_panel_vdd_on, this was the actual root-cause of this failure. With that force_vdd dance completely eliminated, I'm hopeful the original bug stays fixed, too. For reference the old bug, which hopefully doesn't get broken by this: https://bugzilla.kernel.org/show_bug.cgi?id=43163 In any case, regression fixers win over plain bugfixes, so this needs to go in asap. v2: The crucial pieces seems to be to clear the force_vdd flag uncoditionally, too, in edp_panel_off. Looks like this is left behind by the firmware somehow. v3: The Apple firmware seems to switch off the panel on it's own, hence we still need to keep force_vdd on, but properly clear it when switching the panel off.

2012-08-13RDMA/ucma.c: Fix for events with wrong context on iWARPTatyana Nikolova
It is possible for asynchronous RDMA_CM_EVENT_ESTABLISHED events to be generated with ctx->uid == 0, because ucma_set_event_context() copies ctx->uid to the event structure outside of ctx->file->mut. This leads to a crash in the userspace library, since it gets a bogus event. Fix this by taking the mutex a bit earlier in ucma_event_handler.

2012-08-13drm/i915: ensure i2c adapter is all set before adding itJani Nikula
i2c_add_adapter() may do i2c transfers on the bus to detect supported devices. Therefore the adapter needs to be all set before adding it. This was not the case for the bit-banging fallback, resulting in an oops if the device detection GMBUS transfers timed out. Fix the issue by calling i2c_add_adapter() only after intel_gpio_setup().

2012-08-13drm/radeon/kms: add MSAA texture support for r600-evergreenMarek Olšák
Most of the checking seems to be in place already. As you can see, log2(number of samples) resides in LAST_LEVEL. This is required for MSAA support (namely for depth-stencil resolve and blitting between MSAA resources).

2012-08-13drm/radeon: fence virtual address and free it once idle v4Jerome Glisse
Virtual address need to be fenced to know when we can safely remove it. This patch also properly clear the pagetable. Previously it was serouisly broken. Kernel 3.5/3.4 need a similar patch but adapted for difference in mutex locking. v2: For to update pagetable when unbinding bo (don't bailout if bo_va->valid is true). v3: Add kernel 3.5/3.4 comment. v4: Fix compilation warnings.
