The warn on is a bit too much, we will anyway set the dma mask if not set previously. The main reason for this fix is that 4.10-rc1 has a dwc3 change that pass a parent sysdev dev pointer instead of setting the dma mask of its xhci platform device. xhci platform driver can then get more attributes from the sysdev than just the dma mask. The usb core and xhci changes are not yet in 4.10, and a fix like this was preferred instead of taking those big changes this late in the rc-cycle.

Using control_work instead of config_work as the 3rd argument to container_of results in an invalid portdev pointer. Indeed, the work structure is initialized as below: INIT_WORK(&portdev->config_work, &config_work_handler); It leads to a crash when portdev->vdev is dereferenced later. This bug is triggered when the guest uses a virtio-console without multiport feature and receives a config_changed virtio interrupt. Signed-off-by: NG.

This is to silence an uninitialized variable warning in debug output. The problem is this line: pr_debug("vhost_get_vq_desc: head: %d, out: %u in: %u\n", head, out, in); If "head == vq->num" is true on the first iteration then "out" and "in" aren't initialized.

Commit 345857bb ("HID: wacom: generic: Add support for sensor offsets") included a change to the operation and location of the call to 'wacom_add_shared_data' in 'wacom_parse_and_register'. The modifications included moving it higher up so that it would occur before the call to 'wacom_retrieve_hid_descriptor'. This was done to prevent a crash that would have occured when the report containing tablet offsets was fed into the driver with 'wacom_hid_report_raw_event' (specifically: the various 'wacom_wac_*_report' functions were written with the assumption that they would only be called once tablet setup had completed; 'wacom_wac_pen_report' in particular dereferences 'shared' which wasn't yet allocated). Moving the call to 'wacom_add_shared_data' effectively prevented the crash but also broke the sibiling detection code which assumes that the HID descriptor has been read and the various device_type flags set. To fix this situation, we restore the original 'wacom_add_shared_data' operation and location and instead implement an alternative change that can also prevent the crash. Specifically, we notice that the report functions mentioned above expect to be called only for input reports. By adding a check, we can prevent feature reports (such as the offset report) from causing trouble.

The WaDisableLSQCROPERFforOCL workaround has the side effect of disabling an L3SQ optimization that has huge performance implications and is unlikely to be necessary for the correct functioning of usual graphic workloads. Userspace is free to re-enable the workaround on demand, and is generally in a better position to determine whether the workaround is necessary than the DRM is (e.g. only during the execution of compute kernels that rely on both L3 fences and HDC R/W requests). The same workaround seems to apply to BDW (at least to production stepping G1) and SKL as well (the internal workaround database claims that it does for all steppings, while the BSpec workaround table only mentions pre-production steppings), but the DRM doesn't do anything beyond whitelisting the L3SQCREG4 register so userspace can enable it when it sees fit. Do the same on KBL platforms. Improves performance of the GFXBench4 gl_manhattan31 benchmark by 60%, and gl_4 (AKA car chase) by 14% on a KBL GT2 running Mesa master -- This is followed by a regression of 35% and 10% respectively for the same benchmarks and platform caused by my recent patch series switching userspace to use the dataport constant cache instead of the sampler to implement uniform pull constant loads, which caused us to hit more heavily the L3 cache (and on platforms other than KBL had the opposite effect of improving performance of the same two benchmarks). The overall effect on KBL of this change combined with the recent userspace change is respectively 4.6% and 2.6%. SynMark2 OglShMapPcf was affected by the constant cache changes (though it improved as it did on other platforms rather than regressing), but is not significantly affected by this patch (with statistical significance of 5% and sample size 20). v2: Drop some more code to avoid unused variable warning.
