2012-09-04PM / cpuidle: Make ladder governor use the "disabled" state flagRafael J. Wysocki
For the mechanism introduced by commit cbc9ef0 (PM / Domains: Add preliminary support for cpuidle, v2) to work with the ladder governor, that governor should respect the "disabled" state flag added by that commit. Change the ladder governor accordingly. Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2012-09-04Honor state disabling in the cpuidle ladder governorCarsten Emde
There are two cpuidle governors ladder and menu. While the ladder governor is always available, if CONFIG_CPU_IDLE is selected, the menu governor additionally requires CONFIG_NO_HZ. A particular C state can be disabled by writing to the sysfs file /sys/devices/system/cpu/cpuN/cpuidle/stateN/disable, but this mechanism is only implemented in the menu governor. Thus, in a system where CONFIG_NO_HZ is not selected, the ladder governor becomes default and always will walk through all sleep states - irrespective of whether the C state was disabled via sysfs or not. The only way to select a specific C state was to write the related latency to /dev/cpu_dma_latency and keep the file open as long as this setting was required - not very practical and not suitable for setting a single core in an SMP system. With this patch, the ladder governor only will promote to the next C state, if it has not been disabled, and it will demote, if the current C state was disabled. Note that the patch does not make the setting of the sysfs variable "disable" coherent, i.e. if one is disabling a light state, then all deeper states are disabled as well, but the "disable" variable does not reflect it. Likewise, if one enables a deep state but a lighter state still is disabled, then this has no effect. A related section has been added to the documentation.

2012-08-30gma500: Consider CRTC initially active.Forest Bond
[this one ideally should make 3.6 - it fixes the very annoying mode setting bug] This causes the pipe to be forced off prior to initial mode set, which roughly mirrors the behavior of the i915 driver. It fixes initial mode setting on my Intel DN2800MT (Cedarview) board. Without it, mode setting triggers an out-of-range error from the monitor for most modes, but only on initial configuration (i.e. they can be configured successfully from userspace after that).

2012-08-29drm/radeon/atom: powergating fixes for DCE6Alex Deucher
Power gating is per crtc pair, but the powergating registers should be called individually. The hw handles power up/down properly. The pair is powered up if either crtc in the pair is powered up and the pair is not powered down until both crtcs in the pair are powered down. This simplifies programming and should save additional power as the previous code never actually power gated the crtc pair.

The ordering is important and the current drm code wasn't cutting it for modern DIG encoders. We need to have information about crtc before setting up the encoders so I've shifted the ordering a bit. Probably we'll need a full rework akin to danvet's recent intel patchs. This patch fixes numerous issues with DP bridge chips and makes link training much more reliable.

With r600, CB_TARGET_MASK is changed to 0xff, so we must set the number of samples of the second colorbuffer to 1 in order to pass the CS checker.

2012-08-22hwmon: (asus_atk0110) Add quirk for Asus M5A78LLuca Tettamanti
The old interface is bugged and reads the wrong sensor when retrieving the reading for the chassis fan (it reads the CPU sensor); the new interface works fine.

Pull SCSI target fixes from Nicholas Bellinger: "The executive summary includes: - Post-merge review comments for tcm_vhost (MST + nab) - Avoid debugging overhead when not debugging for tcm-fc(FCoE) (MDR) - Fix NULL pointer dereference bug on alloc_page failulre (Yi Zou) - Fix REPORT_LUNs regression bug with pSCSI export (AlexE + nab) - Fix regression bug with handling of zero-length data CDBs (nab) - Fix vhost_scsi_target structure alignment (MST) Thanks again to everyone who contributed a bugfix patch, gave review feedback on tcm_vhost code, and/or reported a bug during their own testing over the last weeks. There is one other outstanding bug reported by Roland recently related to SCSI transfer length overflow handling, for which the current proposed bugfix has been left in queue pending further testing with other non iscsi-target based fabric drivers. As the patch is verified with loopback (local SGL memory from SCSI LLD) + tcm_qla2xxx (TCM allocated SGL memory mapped to PCI HW) fabric ports, it will be included into the next 3.6-rc-fixes PULL request." * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: target: Remove unused se_cmd.cmd_spdtl tcm_fc: rcu_deref outside rcu lock/unlock section tcm_vhost: Fix vhost_scsi_target structure alignment target: Fix regression bug with handling of zero-length data CDBs target/pscsi: Fix bug with REPORT_LUNs handling for SCSI passthrough tcm_vhost: Change vhost_scsi_target->vhost_wwpn to char * target: fix NULL pointer dereference bug alloc_page() fails to get memory tcm_fc: Avoid debug overhead when not debugging tcm_vhost: Post-merge review changes requested by MST tcm_vhost: Fix incorrect IS_ERR() usage in vhost_scsi_map_iov_to_sgl

2012-08-22HID: Remove QUANTA from special drivers listSimon Farnsworth
This QUANTA device is driven by the generic hid-multitouch.ko driver, and therefore shouldn't be in the special drivers list.

2012-08-22vfio: grab vfio_device reference *before* exposing the sucker via fd_install()Al Viro
It's not critical (anymore) since another thread closing the file will block on ->device_lock before it gets to dropping the final reference, but it's definitely cleaner that way... Acked-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-08-22vfio: get rid of vfio_device_put()/vfio_group_get_device* racesAl Viro
we really need to make sure that dropping the last reference happens under the group->device_lock; otherwise a loop (under device_lock) might find vfio_device instance that is being freed right now, has already dropped the last reference and waits on device_lock to exclude the sucker from the list.
