2013-10-09hwmon: (applesmc) Always read until end of dataHenrik Rydberg
The crash reported and investigated in commit 5f4513 turned out to be caused by a change to the read interface on newer (2012) SMCs. Tests by Chris show that simply reading the data valid line is enough for the problem to go away. Additional tests show that the newer SMCs no longer wait for the number of requested bytes, but start sending data right away. Apparently the number of bytes to read is no longer specified as before, but instead found out by reading until end of data. Failure to read until end of data confuses the state machine, which eventually causes the crash. As a remedy, assuming bit0 is the read valid line, make sure there is nothing more to read before leaving the read function. Tested to resolve the original problem, and runtested on MBA3,1, MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on machines before 2012.

2013-10-09mac80211: correctly close cancelled scansEmmanuel Grumbach
__ieee80211_scan_completed is called from a worker. This means that the following flow is possible. * driver calls ieee80211_scan_completed * mac80211 cancels the scan (that is already complete) * __ieee80211_scan_completed runs When scan_work will finally run, it will see that the scan hasn't been aborted and might even trigger another scan on another band. This leads to a situation where cfg80211's scan is not done and no further scan can be issued. Fix this by setting a new flag when a HW scan is being cancelled so that no other scan will be triggered.

2013-10-09target: Fix assignment of LUN in tracepointsRoland Dreier
The unpacked_lun field in the SCSI target tracepoints should be initialized with cmd->orig_fe_lun rather than cmd->se_lun->unpacked_lun for two reasons: - most importantly, if we are in the cmd_complete tracepoint returning a check condition due to no LUN found, cmd->se_lun will be NULL and we'll crash trying to dereference it. - also, in any case, cmd->se_lun->unpacked_lun is an internal index into the target's internal set of LUNs; cmd->orig_fe_lun is much more useful and interesting, since it's the value the initiator actually sent.

2013-10-09drm: move device unregistration into drm_dev_unregister()David Herrmann
Analog to drm_dev_register(), we now provide drm_dev_unregister() which does the reverse. drm_dev_put() is still in place and combines the calls to drm_dev_unregister() and drm_dev_free() so buses don't have to change. *_get() and *_put() are used for reference-counting in the kernel. However, drm_dev_put() definitely does not do any kind of ref-counting. Hence, use the more appropriate *_register(), *_unregister(), *_alloc() and *_free() names.

2013-10-09drm: introduce drm_dev_free() to fix error pathsDavid Herrmann
The error paths in DRM bus drivers currently leak memory as they don't correctly revert drm_dev_alloc(). Introduce drm_dev_free() to free DRM devices which haven't been registered, yet. We must be careful not to introduce any side-effects with cleanups done in drm_dev_free(). drm_ht_remove(), drm_ctxbitmap_cleanup() and drm_gem_destroy() are all fine in that regard.

2013-10-09drm: move drm_lastclose() to drm_fops.cDavid Herrmann

2013-10-09drm: merge device setup into drm_dev_register()David Herrmann
All bus drivers do device setup themselves. This requires us to adjust all of them if we introduce new core features. Thus, merge all these into a uniform drm_dev_register() helper. Note that this removes the drm_lastclose() error path for AGP as it is horribly broken. Moreover, no bus driver called this in any other error path either. Instead, we use the recently introduced AGP cleanup helpers. We also keep a DRIVER_MODESET condition around pci_set_drvdata() to keep semantics.

2013-10-09drm: add drm_dev_alloc() helperDavid Herrmann
Instead of managing device allocation+initialization in each bus-driver, we should do that in a central place. drm_fill_in_dev() already does most of it, but also requires the global drm lock for partial AGP device registration.

2013-10-09drm/nouveau: embed gem object in nouveau_boDavid Herrmann
There is no reason to keep the gem object separately allocated. nouveau is the last user of gem_obj->driver_private, so if we embed it, we can get rid of 8bytes per gem-object. The implementation follows the radeon driver. bo->gem is only valid, iff the bo was created via the gem helpers _and_ iff the user holds a valid gem reference. That is, as the gem object holds a reference to the nouveau_bo. If you use nouveau_ref() to gain a bo reference, you are not guaranteed to also hold a gem reference. The gem object might get destroyed after the last user drops the gem-ref via drm_gem_object_unreference(). Use drm_gem_object_reference() to gain a gem-reference. For debugging, we can use bo->gem.filp != NULL to test whether a gem-bo is valid. However, this shouldn't be used for real functionality to avoid gem-internal dependencies. Note that the implementation follows the previous style. However, we no longer can check for bo->gem != NULL to test for a valid gem object. This wasn't done before, so we should be safe now.
