2008-10-18Export kmap_atomic_pfn for DRM-GEM.Eric Anholt
The driver would like to map IO space directly for copying data in when appropriate, to avoid CPU cache flushing for streaming writes. kmap_atomic_pfn lets us avoid IPIs associated with ioremap for this process.

2008-10-18Export shmem_file_setup for DRM-GEMKeith Packard
GEM needs to create shmem files to back buffer objects. Though currently creation of files for objects could have been driven from userland, the modesetting work will require allocation of buffer objects before userland is running, for boot-time message display.

2008-10-18drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes
Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

2008-10-18drm/cred: wrap task credential accesses in the drm driver.David Howells
Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

2008-10-18separate i915 suspend/resume functions into their own fileJesse Barnes
[Patch against drm-next. Consider this a trial balloon for our new Linux development model.] This is a big chunk of code. Separating it out makes it easier to change without churn on the main i915_drv.c file (and there will be churn as we fix bugs and add things like kernel mode setting).

Fix the SIS DRM memory allocator if the SIS FB built as a module. The SIS DRM code initialises the mm allocation hooks, but _only_ if the SIS FB is not built as a module because it depends on CONFIG_FB_SIS, and that's unset if the SIS FB is not built in.

2008-10-17hwmon: (w83781d) Detect alias chipsJean Delvare
The W83781D and W83782D can be accessed either on the I2C bus or the ISA bus. We must not access the same chip through both interfaces. So far we were relying on the user passing the correct ignore parameter to skip the registration of the I2C interface as suggested by sensors-detect, but this is fragile: the user may load the w83781d driver without running sensors-detect, and the i2c bus numbers are not stable across reboots and hardware changes. So, better detect alias chips in the driver directly, and skip any I2C chip which is obviously an alias of the ISA chip. This is done by comparing the value of 26 selected registers.

The it87 driver doesn't follow the standard sensor type values as documented in Documentation/hwmon/sysfs-interface. It uses value 2 for thermistors instead of value 4. This causes "sensors" to tell the user that the chip is setup for a transistor while it is actually setup for a thermistor. Using value 4 for thermistors solves the problem.

Only request I/O ports 0x295-0x296 instead of the full I/O address range. This solves a conflict with PNP resources on a few motherboards. Also request the I/O ports in two parts (4 low ports, 4 high ports) during device detection, otherwise the PNP resource make the request (and thus the detection) fail. This is the exact same fix that was applied to driver w83781d in March 2008 to address the same problem: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=2961cb22ef02850d90e7a12c28a14d74e327df8d Signed-off-by: Jean Delvare <khali@linux-fr.org>
