2014-06-03dm: change sector_count member in clone_info from sector_t to unsignedMikulas Patocka
It is impossible to create bios with 2^23 or more sectors (the size is stored as a 32-bit byte count in the bio). So we convert some sector_t values to unsigned integers. This is needed for the next commit ("dm: introduce dm_accept_partial_bio") that replaces integer value arguments with pointers, so the size of the integer must match.

2014-05-31drm/radeon: Resume fbcon lastDaniel Vetter
So a few people complained that commit 177cf92de4aa97ec1435987e91696ed8b5023130 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Apr 1 22:14:59 2014 +0200 drm/crtc-helpers: fix dpms on logic which was merged into 3.15-rc1, broke resume on radeons. Strangely git bisect lead everyone to commit 25f397a429dfa43f22c278d0119a60a343aa568f Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Fri Jul 19 18:57:11 2013 +0200 drm/crtc-helper: explicit DPMS on after modeset which was merged long ago and actually part of 3.14. Digging deeper I've noticed (again) that the call to drm_helper_resume_force_mode in the radeon resume handlers was a no-op previously because everything gets shut down on suspend. radeon does this with explicit calls to drm_helper_connector_dpms with DPMS_OFF. But with 177c we now force the dpms state to ON, so suddenly resume_force_mode actually forced the crtcs back on. This is the intention of the change after all, the problem is that radeon resumes the fbdev console layer _before_ restoring the display, through calling fb_set_suspend. And fbcon does an immediate ->set_par, which in turn causes the same forced mode restore to happen. Two concurrent modeset operations didn't lead to happiness. Fix this by delaying the fbcon resume until the end of the readeon resum functions. v2: Fix up a bit of the spelling fail.

2014-05-29firewire: revert to 4 GB RDMA, fix protocols using Memory SpaceStefan Richter
Undo a feature introduced in v3.14 by commit fcd46b34425d "firewire: Enable remote DMA above 4 GB". That change raised the minimum address at which protocol drivers and user programs can register for request reception from 0x0001'0000'0000 to 0x8000'0000'0000. It turned out that at least one vendor-specific protocol exists which uses lower addresses: https://bugzilla.kernel.org/show_bug.cgi?id=76921 For the time being, revert most of commit fcd46b34425d so that affected protocols work like with kernel v3.13 and before. Just keep the valid documentation parts from the regressing commit, and the ability to identify controllers which could be programmed to accept >32 bit physical DMA addresses. The rest of fcd46b34425d should probably be brought back as an optional instead of default feature.

2014-05-27virtio_blk: fix race between start and stop queueMing Lei
When there isn't enough vring descriptor for adding to vq, blk-mq will be put as stopped state until some of pending descriptors are completed & freed. Unfortunately, the vq's interrupt may come just before blk-mq's BLK_MQ_S_STOPPED flag is set, so the blk-mq will still be kept as stopped even though lots of descriptors are completed and freed in the interrupt handler. The worst case is that all pending descriptors are freed in the interrupt handler, and the queue is kept as stopped forever. This patch fixes the problem by starting/stopping blk-mq with holding vq_lock.

2014-05-27drm/i915: Prevent negative relocation deltas from wrappingChris Wilson
This is pure evil. Userspace, I'm looking at you SNA, repacks batch buffers on the fly after generation as they are being passed to the kernel for execution. These batches also contain self-referenced relocations as a single buffer encompasses the state commands, kernels, vertices and sampler. During generation the buffers are placed at known offsets within the full batch, and then the relocation deltas (as passed to the kernel) are tweaked as the batch is repacked into a smaller buffer. This means that userspace is passing negative relocations deltas, which subsequently wrap to large values if the batch is at a low address. The GPU hangs when it then tries to use the large value as a base for its address offsets, rather than wrapping back to the real value (as one would hope). As the GPU uses positive offsets from the base, we can treat the relocation address as the minimum address read by the GPU. For the upper bound, we trust that userspace will not read beyond the end of the buffer. So, how do we fix negative relocations from wrapping? We can either check that every relocation looks valid when we write it, and then position each object such that we prevent the offset wraparound, or we just special-case the self-referential behaviour of SNA and force all batches to be above 256k. Daniel prefers the latter approach. This fixes a GPU hang when it tries to use an address (relocation + offset) greater than the GTT size. The issue would occur quite easily with full-ppgtt as each fd gets its own VM space, so low offsets would often be handed out. However, with the rearrangement of the low GTT due to capturing the BIOS framebuffer, it is already affecting kernels 3.15 onwards. I think only IVB+ is susceptible to this bug, but the workaround should only kick in rarely, so it seems sensible to always apply it. v3: Use a bias for batch buffers to prevent small negative delta relocations from wrapping. v4 from Daniel: - s/BIAS/BATCH_OFFSET_BIAS/ - Extract eb_vma_misplaced/i915_vma_misplaced since the conditions were growing rather cumbersome. - Add a comment to eb_get_batch explaining why we do this. - Apply the batch offset bias everywhere but mention that we've only observed it on gen7 gpus. - Drop PIN_OFFSET_FIX for now, that slipped in from a feature patch. v5: Add static to eb_get_batch, spotted by 0-day tester.

2014-05-27drm/i915: Only copy back the modified fields to userspace from execbufferChris Wilson
We only want to modifiy a single field in the userspace view of the execbuffer command buffer, so explicitly change that rather than copy everything back again. This serves two purposes: 1. The single fields are much cheaper to copy (constant size so the copy uses special case code) and much smaller than the whole array. 2. We modify the array for internal use that need to be masked from the user. Note: We need this backported since without it the next bugfix will blow up when userspace recycles batchbuffers and relocations.

2014-05-27drm/i915: Fix dynamic allocation of physical handlesChris Wilson
A single object may be referenced by multiple registers fundamentally breaking the static allotment of ids in the current design. When the object is used the second time, the physical address of the first assignment is relinquished and a second one granted. However, the hardware is still reading (and possibly writing) to the old physical address now returned to the system. Eventually hilarity will ensue, but in the short term, it just means that cursors are broken when using more than one pipe. v2: Fix up leak of pci handle when handling an error during attachment, and avoid a double kmap/kunmap.

Most of the affected models share pnp-ids for the touchpad. So switching to pnp-ids give us 2 advantages: 1) It shrinks the quirk list 2) It will lower the new quirk addition frequency, ie the recently added W540 quirk would not have been necessary since it uses the same LEN0034 pnp ids as other models already added before it As an added bonus it actually puts the quirk on the actual psmouse, rather then on the machine, which is technically more correct.

In commit 9e8269de, support was added for ntc_thermistor devices being declared in the device tree and implemented on top of IIO. With that change, a dependency was added to the ntc_thermistor driver: depends on (!OF && !IIO) || (OF && IIO) This construct has the drawback that the driver can no longer be selected when OF is set and IIO isn't, nor when IIO is set and OF is not. This is a regression for the original users of the driver. As the new code depends on IIO and is useless without OF, include it only if both are enabled, and set the dependencies accordingly. This is clearer, more simple and more correct.

2014-05-23clk: divider: Fix table round up functionMaxime COQUELIN
Commit 1d9fe6b97 ("clk: divider: Fix best div calculation for power-of-two and table dividers") introduces a regression in its _table_round_up function. When the divider passed to this function is greater than the max divider available in the table, this function returns table's max divider. Problem is that it causes an infinite loop in clk_divider_bestdiv() because _next_div() will never return a value greater than maxdiv. Instead of returning table's max divider, this patch returns INT_MAX.

2014-05-22[SCSI] scsi_transport_sas: move bsg destructor into sas_rphy_removeJoe Lawrence
The recent change in sysfs, bcdde7e221a8750f9b62b6d0bd31b72ea4ad9309 "sysfs: make __sysfs_remove_dir() recursive" revealed an asymmetric rphy device creation/deletion sequence in scsi_transport_sas: modprobe mpt2sas sas_rphy_add device_add A rphy->dev device_add B sas_device transport class device_add C sas_end_device transport class device_add D bsg class rmmod mpt2sas sas_rphy_delete sas_rphy_remove device_del B device_del C device_del A sysfs_remove_group recursive sysfs dir removal sas_rphy_free device_del D warning where device A is the parent of B, C, and D. When sas_rphy_free tries to unregister the bsg request queue (device D above), the ensuing sysfs cleanup discovers that its sysfs group has already been removed and emits a warning, "sysfs group... not found for kobject 'end_device-X:0'". Since bsg creation is a side effect of sas_rphy_add, move its complementary removal call into sas_rphy_remove. This imposes the following tear-down order for the devices above: D, B, C, A. Note the sas_device and sas_end_device transport class devices (B and C above) are created and destroyed both via the list match traversal in attribute_container_device_trigger, so the order in which they are handled is fixed. This is fine as long as they are deleted before their parent device.

2014-05-22bonding: Send ALB learning packets using the right sourceVlad Yasevich
ALB learning packets are currentlyalways sent using the slave mac address for all vlans configured on top of bond. This is not always correct, as vlans may change their mac address. This patch introduced a concept of strict matching where the source of learning packets can either strictly match the address passed in, or it can determine a more correct address to use. There are 3 casese to consider: 1) Switchover. In this case, we have a new active slave and we need tell the switch about all addresses available on the slave. 2) Monitor. We'll periodically refresh learning info for all slaves. In this case, we refresh all addresses for current active, and just the slave address for other slaves. 3) Teaching of disabled adddress. This happens as part of the failover and in this case, we alwyas to use just the address provided.

TLB/ALB learning packets always assume 802.1Q vlan protocol, but that is no longer the case since we now have support for Q-in-Q on top of bonding. Pass the vlan protocol to alb_send_lp_vid() so that the packets are properly tagged.
