2010-09-07drm/i915: Fix offset page-flips on i965+Chris Wilson
i965 uses the Display Registers to compute the offset from the display base so the new base does not need adjusting when flipping. The older chipsets use a fence to access the display and so do perceive the surface as linear and have a single base register which is reprogrammed using the flip.

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.)

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.

2010-09-03usb: allow drivers to use allocated bandwidth until unboundThadeu Lima de Souza Cascardo
When using the remove sysfs file, the device configuration is set to -1 (unconfigured). This eventually unbind drivers with the bandwidth_mutex held. Some drivers may call functions that hold said mutex, like usb_reset_device. This is the case for rtl8187, for example. This will lead to the same process holding the mutex twice, which deadlocks. Besides, according to Alan Stern: "The deadlock problem probably could be handled somehow, but there's a separate issue: Until the usb_disable_device call finishes unbinding the drivers, the drivers are free to continue using their allocated bandwidth. We musn't change the bandwidth allocations until after the unbinding is done. So this patch is indeed necessary." Unbinding the driver before holding the bandwidth_mutex solves the problem. If any operation after that fails, drivers are not bound again. But that would be a problem anyway that the user may solve resetting the device configuration to one that works, just like he would need to do in most other failure cases.

2010-09-03USB: option: fix incorrect novatel entriesDirk De Schepper
Unfortunately some of the hardware PID belonging to auto-install CDROM (AICD) of Novatel modems found their way into the option module. This causes the AICD to be treated as a modem in stead of a disk. Since the modem ports do not appear until after the AICD is ejected, this essentially disables the modem. After a couple of minutes the AICD should auto-eject, but it is just too long a wait. The frequency of the failure seems to depend on both the hardware and the linux distribution. Here is a patch that fixes this up, and also adds a couple of new PID, offering some explanations and removing some incomplete and unnecessary comments.

2010-09-03USB: rndis: section mismatch fixHenrik Kretzschmar
This patch removes the following section mismatch warning, by moving the function rndis_init() from .init.text to .text. WARNING: vmlinux.o(.text+0x1aeca5a): Section mismatch in reference from the function rndis_bind_config() to the function .init.text:rndis_init() The function rndis_bind_config() references the function __init rndis_init(). This is often because rndis_bind_config lacks a __init annotation or the annotation of rndis_init is wrong.

2010-09-03USB: ehci-ppc-of: problems in unwindDan Carpenter
The iounmap(ehci->ohci_hcctrl_reg); should be the first thing we do because the ioremap() was the last thing we did. Also if we hit any of the goto statements in the original code then it would have led to a NULL dereference of "ehci". This bug was introduced in: 796bcae7361c "USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3]" I modified the few lines in front a little so that my code didn't obscure the return success code path.
