2008-11-11drm/radeon: map registers at load timeDave Airlie
Now that the radeon driver has suspend/resume functions, it needs to map its registers at load time or it will likely crash if a suspend operation occurs before the driver has been initialized. This patch moves the register mapping code from firstopen to load and makes the mapping into a _DRM_DRIVER one so that the core won't remove it at lastclose time. Fixes (at least partially) kernel bz #11891. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@linux.ie>

2008-11-11i915: Remove racy delayed vblank swap ioctl.Eric Anholt
When userland detected that this ioctl was supported (by version number check), it used it in a racy way -- dispatch delayed swap, wait for vblank, continue rendering. As there was no mechanism for it to wait for the swap to finish, sometimes it would render before the swap and garbage would be displayed on the screen. By removing the ioctl and returning -EINVAL, userland returns to its previous, correct rendering path of waiting for a vblank then dispatching a swap. The only path that could have used this ioctl correctly was page flipping, which relied on only one client running and emitting wait-for-vblank-before-rendering in the command stream. That path also falls back correctly, at the performance cost of not being able to queue up rendering before the flip occurs.

2008-11-10libata: revert convert-to-block-tagging patchesTejun Heo
This patch reverts the following three commits which convert libata to use block layer tagging. 43a49cbdf31e812c0d8f553d433b09b421f5d52c e013e13bf605b9e6b702adffbe2853cfc60e7806 2fca5ccf97d2c28bcfce44f5b07d85e74e3cd18e Although using block layer tagging is the right direction, due to the tight coupling among tag number, data structure allocation and hardware command slot allocation, libata doesn't work correctly with the current conversion. The biggest problem is guaranteeing that tag 0 is always used for non-NCQ commands. Due to the way blk-tag is implemented and how SCSI starts and finishes requests, such guarantee can't be made. I'm not sure whether this would actually break any low level driver but it doesn't look like a good idea to break such assumption given the frailty of ATA controllers. So, for the time being, keep using the old dumb in-libata qc allocation.

2008-11-09Don't ask twice about not including staging driversLinus Torvalds
The "Exclude staging drivers" question is there so that we don't build staging drivers for allyesconfig or allnoconfig settings, but it's very irritating when you've already said "no" to staging drivers earlier. There is absolutely no point in declining twice - once you've declined the staging drivers, you're done.

2008-11-07ACPI video: if no ACPI backlight support, use vendor driversThomas Renninger
If an ACPI graphics device supports backlight brightness functions (cmp. with latest ACPI spec Appendix B), let the ACPI video driver control backlight and switch backlight control off in vendor specific ACPI drivers (asus_acpi, thinkpad_acpi, eeepc, fujitsu_laptop, msi_laptop, sony_laptop, acer-wmi). Currently it is possible to load above drivers and let both poke on the brightness HW registers, the video and vendor specific ACPI drivers -> bad. This patch provides the basic support to check for BIOS capabilities before driver loading time. Driver specific modifications are in separate follow up patches. "acpi_backlight=vendor" Prever vendor driver over ACPI driver for backlight. "acpi_backlight=video" (default) Prever ACPI driver over vendor driver for backlight.

2008-11-07ACPI: video: Ignore devices that aren't present in hardwareThomas Renninger
This is a reimplemention of commit 0119509c4fbc9adcef1472817fda295334612976 from Matthew Garrett <mjg59@srcf.ucam.org> This patch got removed because of a regression: ThinkPads with a Intel graphics card and an Integrated Graphics Device BIOS implementation stopped working. In fact, they only worked because the ACPI device of the discrete, the wrong one, got used (via int10). So ACPI functions were poking on the wrong hardware used which is a sever bug. The next patch provides support for above ThinkPads to be able to switch brightness via the legacy thinkpad_acpi driver and automatically detect when to use it. Original commit message from Matthew Garrett: Vendors often ship machines with a choice of integrated or discrete graphics, and use the same DSDT for both. As a result, the ACPI video module will locate devices that may not exist on this specific platform. Attempt to determine whether the device exists or not, and abort the device creation if it doesn't. http://bugzilla.kernel.org/show_bug.cgi?id=9614 Signed-off-by: Thomas Renninger <trenn@suse.de> Acked-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Len Brown <len.brown@intel.com>

2008-11-07[netdrvr] usb/hso: Cleanup rfkill error handlingJonathan McDowell
Yup, this appears to be the problem, thanks. I think &hso_net->net->dev is more intuitive for the error message, so I've used that. I've also added missing line endings on the error messages and set our local rfkill structure element to NULL on failure so we don't try to call rfkill_unregister on driver removal if we failed to register at all. The patch below Works For Me (TM); the device is detected fine, can be removed without problems and connects ok. I'll have a prod at why the rfkill stuff isn't working next, but I believe this cleanup of the error handling is appropriate no matter what the issue with registration is.
