rather than implementing different ways leading to confusion. This allows multiple gate_enable/disable's in the tuner_read/write functions, thereby lesser number of I/O operations throughout, eventually leading to better results. As a side effect demods that detect the STOP bit for auto closing of the gate can be avoided, thereby a very minimal gain in disabling the auto detect feature as well. Improves readability on the device control. Signed-off-by: Manu Abraham <manu@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-11-11RDMA/cxgb3: deadlock in iw_cxgb3 can cause hang when configuring interface.Steve Wise
When the iw_cxgb3 module's cxgb3_client "add" func gets called by the cxgb3 module, the iwarp driver ends up calling the ethtool ops get_drvinfo function in cxgb3 to get the fw version and other info. Currently the iwarp driver grabs the rtnl lock around this down call to serialize. As of 2.6.27 or so, things changed such that the rtnl lock is held around the call to the netdev driver open function. Also the cxgb3_client "add" function doesn't get called if the device is down. So, if you load cxgb3, then load iw_cxgb3, then ifconfig up the device, the iw_cxgb3 add func gets called with the rtnl_lock held. If you load cxgb3, ifconfig up the device, then load iw_cxgb3, the add func gets called without the rtnl_lock held. The former causes the deadlock, the latter does not. In addition, there are iw_cxgb3 sysfs handlers that also can call down into cxgb3 to gather the fw and hw versions. These can be called concurrently on different processors and at any time. Thus we need to push this serialization down in the cxgb3 driver get_drvinfo func. The fix is to remove rtnl lock usage, and use a per-device lock in cxgb3.

2008-11-11myri10ge: fix stop/go ordering even moreBrice Goglin
The doorbell writes may be seen out of order by the firmware if they are in WC memory since the tx spin(un)lock does not flush WC writes. Hence if the "stop" is written on a different CPU than the "go", it is possible that the stop will arrive after the go unless we add an explicit memory barrier (and mmiowb() is not enough). It fixes transmit hangs in multi tx queue mode. Signed-off-by: Brice Goglin <brice@myri.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-11-11drm/i915: Filter pci devices based on PCI_CLASS_DISPLAY_VGADave Airlie
This fixes hangs on 855-class hardware by avoiding double attachment of the driver due to the stub second head device having the same pci id as the real device. Other DRM drivers probably want this treatment as well, but I'm applying it just to this one for safety. But we should clean up the drm_pciids.h mess now so that each driver has its own pci id list header in its own directory. Lets do that in the next release.

2008-11-11libata: fix last_reset timestamp handlingTejun Heo
ehc->last_reset is used to ensure that resets are not issued too close to each other. It's initialized to jiffies minus one minute on EH entry. However, when new links are initialized after PMP is probed, new links have zero for this timestamp resulting in long wait depending on the current jiffies. This patch makes last_set considered iff ATA_EHI_DID_RESET is set, in which case last_reset is always initialized. As an added precaution, WARN_ON() is added so that warning is printed if last_reset is in future. This problem is spotted and debugged by Shane Huang.

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.

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.

2008-11-07ACPI 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.
