2014-06-09drm/radeon: use lower_32_bits where appropriateChristian König
Replace occurrences of "v & 0xffffffff" with lower_32_bits(v) when it's next to an upper_32_bits(v). Also remove unnecessary "upper_32_bits(v) & 0xffffffff" code snippets. Signed-off-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2014-06-10raid5: speedup sync_request processingEivind Sarto
The raid5 sync_request() processing calls handle_stripe() within the context of the resync-thread. The resync-thread issues the first set of read requests and this adds execution latency and slows down the scheduling of the next sync_request(). The current rebuild/resync speed of raid5 is not much faster than what rotational HDDs can sustain. Testing the following patch on a 6-drive array, I can increase the rebuild speed from 100 MB/s to 175 MB/s. The sync_request() now just sets STRIPE_HANDLE and releases the stripe. This creates some more parallelism between the resync-thread and raid5 kernel daemon. Signed-off-by: Eivind Sarto <esarto@fusionio.com> Signed-off-by: NeilBrown <neilb@suse.de>

git://anongit.freedesktop.org/tegra/linux into drm-next drm/tegra: Changes for v3.16-rc1 The majority of these changes are a slew of cleanups across the board. A more noteworthy change is the addition of drm_dev_set_unique() and the conversion of the Tegra DRM driver to use it. This allows us to get rid of the host1x drm_bus implementation. Other USB and platform drivers can be changed in a similar way. Unfortunately for most PCI devices there is some userspace that relies on the old functionality and cannot be as easily converted. HDMI and hardware cursor support is added for Tegra124. The SOR output gains support for exposing CRCs via debugfs, which can be used for automated testing. Many values that were hardcoded in the SOR/eDP code are now computed at runtime to increase compatibility with more devices. * tag 'drm/tegra/for-3.16-rc1' of git://anongit.freedesktop.org/tegra/linux: (47 commits) drm/tegra: sor - Remove obsolete comment drm/tegra: sor - Enable only the necessary number of lanes drm/tegra: sor - Power on only the necessary lanes drm/tegra: sor - Do not program interlaced mode registers drm/tegra: sor - Do not hardcode link speed drm/tegra: sor - Do not hardcode number of blank symbols drm/tegra: sor - Don't hardcode link parameters drm/tegra: sor - Change power down ordering drm/tegra: sor - Fix copy/paste error drm/tegra: sor - Remove pixel clock rounding drm/tegra: sor - Make debugfs setup consistent drm/tegra: sor - Recursively remove debugfs tree drm/tegra: dp - Mark the connector as hotplug capable drm/tegra: dp - Implement hotplug detection in work queue drm/tegra: Add hardware cursor support drm/tegra: Remove host1x drm_bus implementation drm: Document how to register devices without struct drm_bus drm: Add device registration documentation drm: Introduce drm_dev_set_unique() gpu: host1x: Rename internal functions for clarity ...

We've observed the missing pvpanic call at panic, and it turned out that this was blocked by the broken notifier of drm_fb_helper, where scheduling may be called during switching to the fb console. It's fairly difficult to fix the drm_fb problem and a quick fix isn't foreseen, a simpler solution for the missing pvpanic call would be just to call this earlier.

2014-06-09drm/i915: Kick out vga consoleDaniel Vetter
Touching the VGA resources on an IVB EFI machine causes hard hangs when we then kick out the efifb. Ouch.

Also, we want this to make I915_FBDEV=n safe. v2: Rebase and pimp commit message. v3: We also need to unregister the vga console, otherwise the unbind of the fb console before module unload might resurrect it again. v4: Ignore errors when the vga console is already unregistered - this can happen when e.g. reloading i915.ko.

2014-06-09vhost: move memory pointer to VQsMichael S. Tsirkin
commit 2ae76693b8bcabf370b981cd00c36cd41d33fabc vhost: replace rcu with mutex replaced rcu sync for memory accesses with VQ mutex locl/unlock. This is correct since all accesses are under VQ mutex, but incomplete: we still do useless rcu lock/unlock operations, someone might copy this code into some other context where this won't be right. This use of RCU is also non standard and hard to understand. Let's copy the pointer to each VQ structure, this way the access rules become straight-forward, and there's no need for RCU anymore.

2014-06-09vhost-net: extend device allocation to vmallocMichael S. Tsirkin
Michael Mueller provided a patch to reduce the size of vhost-net structure as some allocations could fail under memory pressure/fragmentation. We are still left with high order allocations though. This patch is handling the problem at the core level, allowing vhost structures to use vmalloc() if kmalloc() failed. As vmalloc() adds overhead on a critical network path, add __GFP_REPEAT to kzalloc() flags to do this fallback only when really needed. People are still looking at cleaner ways to handle the problem at the API level, probably passing in multiple iovecs. This hack seems consistent with approaches taken since then by drivers/vhost/scsi.c and net/core/dev.c Based on patch by Romain Francoise.

2014-06-09cpufreq: governor: remove copy_prev_load from 'struct cpu_dbs_common_info'Viresh Kumar
'copy_prev_load' was recently added by commit: 18b46ab (cpufreq: governor: Be friendly towards latency-sensitive bursty workloads). It actually is a bit redundant as we also have 'prev_load' which can store any integer value and can be used instead of 'copy_prev_load' by setting it zero. True load can also turn out to be zero during long idle intervals (and hence the actual value of 'prev_load' and the overloaded value can clash). However this is not a problem because, if the true load was really zero in the previous interval, it makes sense to evaluate the load afresh for the current interval rather than copying the previous load. So, drop 'copy_prev_load' and use 'prev_load' instead. Update comments as well to make it more clear. There is another change here which was probably missed by Srivatsa during the last version of updates he made. The unlikely in the 'if' statement was covering only half of the condition and the whole line should actually come under it. Also checkpatch is made more silent as it was reporting this (--strict option): CHECK: Alignment should match open parenthesis + if (unlikely(wall_time > (2 * sampling_rate) && + j_cdbs->prev_load)) { Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Reviewed-by: Srivatsa S.

2014-06-08i40e: implement anti-spoofing for VFsMitch Williams
Our hardware supports VF antispoofing for both MAC addresses and VLANs. Enable this feature by default for all VFs and implement the netdev op to control it from the command line.

We don't need to complain in the log about mac addresses that can't be deleted because they don't exist. Change-ID: I4e6370df175bf72726f06d2206c03bcbfded8387 Signed-off-by: Shannon Nelson <shannon.nelson@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

This was a vestige of early driver development that no longer has any actual use. Change-ID: I95b5b19c4bbfaff8759197af671ebaf716cb6ab5 Signed-off-by: Shannon Nelson <shannon.nelson@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2014-06-08i40e: allow for more VSIsMitch Williams
The number of VSIs that the firmware reports to us is a guaranteed minimum, not an absolute maximum. The hardware actually supports far more than the reported value, which we often need. To allow for this, we allocate space for a larger number of VSIs than is guaranteed by the firmware, with the knowledge that we may fail to get them all in the future. Note that we are just allocating pointers here, the actual (much larger) VSI structures are allocated on demand.
