git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: "These include two fixes for recent regressions related to ACPI, a cpufreq fix for breakage overlooked by a previous fix commit, two intel_pstate fixes for stuff added during the 3.13 cycle that need to go into -stable, three fixes for older bugs that also are -stable candidates, ACPI video blacklist changes related to BIOSes that behave in a special way on Windows 8, several build fixes for CONFIG_PM_SLEEP unset in ACPI drivers and an ACPI driver cleanup. Specifics: - Fix for a recent probing regression in the nouveau driver introduced by an ACPI change related to the handling of _DSM from Jiang Liu. - Fix for a dock station sysfs attribute that stopped working correctly after recent changes in the ACPI core. - cpufreq fix taking care of broken code related to CPU removal and overlooked by a previous recent fix in that area. From Viresh Kumar. - Two intel_pstate fixes related to Baytrail support added during the 3.13 cycle (candidates for -stable) from Dirk Brandewie. - ACPI video fix removing duplicate brightness values from the _BCL table which makes its user space interface behave sanely. From Hans de Goede. - Fix for the powernow-k8 cpufreq driver making it initialize its per-CPU data structures correctly from Srivatsa S Bhat. - Fix for an obscure memory leak in the ACPI PCI interrupt allocation code (related to ISA) from Tomasz Nowicki. - ACPI video blacklist changes moving several systems that should use the native backlight interface instead of the ACPI one from the general ACPI _OSI blacklist the the ACPI video driver's blacklist where they belong. This consists of an ACPI video driver update from Aaron Lu and a revert of a previous commit adding systems to the ACPI _OSI blacklist requested by Takashi Iwai. - Several fixes for build issues in ACPI drivers occuring when CONFIG_PM_SLEEP is unset from Shuah Khan. - Fix for an sscanf() format string in the ACPI Smart Battery Subsystem (SBS) driver from Luis G.F" * tag 'pm+acpi-3.14-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: intel_pstate: Add support for Baytrail turbo P states intel_pstate: Use LFM bus ratio as min ratio/P state ACPI / nouveau: fix probing regression related to _DSM Revert "ACPI: Blacklist Win8 OSI for some HP laptop 2013 models" ACPI / video: Add systems that should favour native backlight interface ACPI / video: Filter the _BCL table for duplicate brightness values cpufreq: powernow-k8: Initialize per-cpu data-structures properly cpufreq: remove sysfs link when a cpu != policy->cpu, is removed ACPI / PCI: Fix memory leak in acpi_pci_irq_enable() ACPI / dock: Make 'docked' sysfs attribute work as documented ACPI / SBS: Fix incorrect sscanf() string ACPI / thermal: fix thermal driver compile error when CONFIG_PM_SLEEP is undefined ACPI / SBS: fix SBS driver compile error when CONFIG_PM_SLEEP is undefined ACPI / fan: fix fan driver compile error when CONFIG_PM_SLEEP is undefined ACPI / button: fix button driver compile error when CONFIG_PM_SLEEP is undefined ACPI / battery: fix battery driver compile error when CONFIG_PM_SLEEP is undefined ACPI / AC: fix AC driver compile error when CONFIG_PM_SLEEP is undefined
2014-02-20ACPI / nouveau: fix probing regression related to _DSMGravatar Jiang Liu 1-2/+24
Fix regression caused by commit b072e53, which breaks loading nouveau driver on optimus laptops. On some platforms, ACPI _DSM method (nouveau_op_dsm_muid, function 0) has special requirements on the fourth parameter, which is different from ACPI specifications. So revert to the private implementation to check availability of _DSM functions instead of using common acpi_check_dsm() interface.

2014-02-18drm: add DRM_CAPs for cursor sizeGravatar Alex Deucher 1-0/+12
Some hardware may not support standard 64x64 cursors. Add a drm cap to query the cursor size from the kernel. Some examples include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32). This allows things like device specific ddxes to remove asics specific logic and also allows xf86-video-modesetting to work properly with hw cursors on this hardware. Default to 64 if the driver doesn't specify a size. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Rob Clark <robdclark@gmail.com>

Commit a55409066 ("drm/nv50-: map TTM_PL_SYSTEM through a BAR for CPU access") made it possible to work with tiled memory. However mem->mm_node is not a nouveau_mem for AGP-using pre-NV50 cards, but a drm_mm_node, as created by the ttm_bo_manager_func. As such, extend the untiled check to explicitly include all pre-nv50 cards.

2014-02-07drm/i915: Disable dp aux irq on g4xGravatar Daniel Vetter 3-8/+9
Apparently it's broken in the exact same way as the gmbus irq. For reference of the full story see commit c12aba5aa0e60b7947bc8b6ea25ef55c4acf81a4 Author: Jiri Kosina <jkosina@suse.cz> Date: Tue Mar 19 09:56:57 2013 +0100 drm/i915: stop using GMBUS IRQs on Gen4 chips The effect is that we have a storm of unclaimed interrupts on the legacy irq line. If that one is used by a different device then the kernel will complain and rather quickly kill the irq source. Which breaks any device trying to actually use the legacy irq line. This regression has been introduced commit 4aeebd7443e36b0a40032e518a9338f48bd27efc Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Oct 31 09:53:36 2013 +0100 drm/i915: dp aux irq support for g4x/vlv Note that disabling MSI works around the issue, but we can't do that since apparently then the hw will miss interrupts. At least if relevant comments in i915_irq.c are accurate. v2: Cross-reference dp aux and gmbus gen4 comments. v3: Consolidate harder into i915_drv.h as suggested by Chris.

2014-02-07drm/msm: bigger synchronization hammerGravatar Rob Clark 2-7/+5
Because we use a list_head in the bo to track it's position in a submit, we need to serialize at a higher layer. Otherwise there are problems when multiple contexts are SUBMIT'ing in parallel cmdstreams referencing a shared bo. Signed-off-by: Rob Clark <robdclark@gmail.com>

2014-02-07drm/exynos: Fix multiplatform breakage for ipp/gscGravatar Tushar Behera 2-3/+2
There is no need to include "plat/map-base.h" in ipp driver. Remove this and enable this driver for multi-platform. However gsc driver is not multiplatform compliant yet, so make the compilation conditional upon !ARCH_MULTIPLATFORM.
