2010-09-07drm/i915: Tightly scope intel_encoder to prevent invalid useChris Wilson
We reset intel_encoder for every matching encoder whilst iterating over the encoders attached to this crtc when changing mode. As such in a cloned configuration intel_encoder may not correspond to the correct is_edp encoder. By scoping intel_encoder to the loop, not only is the compiler able to spot this mistake, we also improve readiability for ourselves. [It might not be a mistake, within this function it is unclear as to whether it is permissable for eDP to be cloned...] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2010-09-07drm/i915/sdvo: Restore guess of the DDC bus in absence of VBIOSChris Wilson
If the VBIOS tells us the mapping of the SDVO device onto the DDC bus, use it. However, if there is no VBIOS available that mapping is uninitialised and we should fallback to our earlier guess. Fix regression introduced in b1083333 (which in turn is a fix for the regression caused by the introduction of this guess, 14571b4).

2010-09-06drm/i915: overlay on gen2 can't address above 1GDaniel Vetter
So set the coherent dma mask accordingly. This dma mask is only used for physical objects, so it won't really matter allocation-wise. Now this never really surfaced because sane 32bit kernels only have 1G of lowmem. But some eager testers (distros?) still carry around the patch to adjust lowmem via a kconfig option. And the kernel seems to favour high allocations on boot-up, hence the overlay blowing up reliably. Because the patch is tiny and nicely shows how broken gen2 is it's imho worth to merge despite the fact that mucking around with the lowmem/ highmem division is (no longer) supported.

2010-09-07drm: Do not force 1024x768 modes on unknown connectorsChris Wilson
Only fallback to a set of default modes on a connector iff that connector is known to be connected. The issue occurs that with limited hardware which cannot probe a connector and so reports the connector status as unknown will then attempt to retrieve the modes for it during drm_helper_probe_single_connector_modes(). Should that fail, the helper then generates a default set which fools the fb_helper and causes havoc with the console and beyond.

2010-09-07drm/kms: Add a module parameter to disable pollingChris Wilson
Polling for a VGA device on an old system can be quite expensive, causing latencies on the order of 600ms. As we hold the mode mutex for this time and also need the same mutex to move the cursor, we trigger a user-visible stall. The real solution would involve improving the granulatity of the locking and so perhaps performing some of the probing not under the lock or some other updates can be done under different locks. Also reducing the cost of probing for a non-existent monitor would be worthwhile. However, exposing a parameter to disable polling is a simple workaround in the meantime. In order to accommodate users turning polling on and off at runtime, the polling is potentially re-enabled on every probe. This is coupled to the user calling xrandr, which seems to be a vaild time to reset the polling timeout since the information on the connection has just been updated. (The presumption being that all connections are probed in a single xrandr pass, which is currently valid.)

2010-09-06vhost: fix attach to cgroups regressionMichael S. Tsirkin
Since 2.6.36-rc1, non-root users of vhost-net fail to attach if they are in any cgroups. The reason is that when qemu uses vhost, vhost wants to attach its thread to all cgroups that qemu has. But we got the API backwards, so a non-priveledged process (Qemu) tried to control the priveledged one (vhost), which fails. Fix this by switching to the new cgroup_attach_task_all, and running it from the vhost thread. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

Fix missing functions for net_device_ops. It's a bug when porting the drivers from 2.6.27 to 2.6.32. In 2.6.27, the default functions for Ethernet, like eth_change_mtu(), were assigned by ether_setup(). But in 2.6.32, these function pointers moved to net_device_ops structure and no longer be assigned in ether_setup(). So we need to set these functions in our driver code. It will ensure the MTU won't be set beyond 1500. Otherwise, this can cause an error on the server side, because the HyperV linux driver doesn't support jumbo frame yet.
