2013-03-18drm/nouveau/therm: remove some confusion introduced by therm_modeMartin Peres4-8/+8
The kernel message "[ PTHERM][0000:01:00.0] Thermal management: disabled" is misleading as it actually means "fan management: disabled". This patch fixes both the source and the message to improve readability. Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-03-18drm/nouveau/therm: do not make assumptions on temperatureMartin Peres1-3/+3
In nouveau_therm_sensor_event, temperature is stored as an uint8_t even though the original interface returns an int. This change should make it more obvious when the sensor is either very-ill-calibrated or when we selected the wrong sensor style on the nv40 family. Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-03-18drm/nv40/therm: increase the sensor's settling delay to 20msMartin Peres1-1/+2
Based on my experience, 10ms wasn't always enough. Let's bump that to a little more. If this turns out to be insufficient-enough again, then an approach based on letting the sensor settle for several seconds before starting polling on the temperature would be better suited. This way, boot time wouldn't be impacted by those waits too much. Signed-off-by: Martin Peres <martin.peres@labri.fr> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2013-03-18drm/nv40/therm: improve selection between the old and the new styleMartin Peres1-12/+38
The condition to select between the old and new style was a thinko as rnndb orders chipsets based on their release date (or general chronologie hw-wise) and not based on their chipset number. As the nv40 family is a mess when it comes to numbers, this patch introduces a switch-based selection between the old and new style.

2013-03-04drm/nouveau/i2c: drop parent refcount when creating portsBen Skeggs1-0/+1
Fixes issue where i2c subdev never gets destroyed due to its subobjects holding references. This will mean the i2c subdev refcount goes negative during its destruction, but this isn't an issue in practice. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2013-03-02ext4: enable quotas before orphan cleanupJan Kara1-10/+10
When using quota feature we need to enable quotas before orphan cleanup so that changes happening during it are properly reflected in quota accounting. Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
2013-03-02ext4: don't allow quota mount options when quota feature enabledJan Kara1-7/+26
So far we silently ignored when quota mount options were set while quota feature was enabled. But this can create confusion in userspace when mount options are set but silently ignored and also creates opportunities for bugs when we don't properly test all quota types. Actually ext4_mark_dquot_dirty() forgets to test for quota feature so it was dependent on journaled quota options being set. OTOH ext4_orphan_cleanup() tries to enable journaled quota when quota options are specified which is wrong when quota feature is enabled.

2013-03-02metag: copy devicetree to non-init memoryJames Hogan3-0/+20
Make a copy of the device tree blob in non-init memory. It is required when using built-in device tree files that the platform code copies the blob to non-init memory prior to calling unflatten_device_tree(), otherwise the strings that the device tree refer to will get poisoned and potentially reused, breaking later reading of the device tree post-init (such as compatible matching in modules, debugfs, and the procfs interface).

2013-03-02metag: move irq enable out of irqflags.h on SMPJames Hogan2-7/+20
The SMP version of arch_local_irq_enable() uses preempt_disable(), but <asm/irqflags.h> doesn't include <linux/preempt.h> causing the following errors on SMP when pstore/ftrace is enabled (caught by buildbot smp allyesconfig): In file included from include/linux/irqflags.h:15, from fs/pstore/ftrace.c:16: arch/metag/include/asm/irqflags.h: In function 'arch_local_irq_enable': arch/metag/include/asm/irqflags.h:84: error: implicit declaration of function 'preempt_disable' arch/metag/include/asm/irqflags.h:86: error: implicit declaration of function 'preempt_enable_no_resched' However <linux/preempt.h> cannot be easily included from <asm/irqflags.h> as it can cause circular include dependencies in the !SMP case, and potentially in the SMP case in the future. Therefore move the SMP implementation of arch_local_irq_enable() into traps.c and use an inline version of get_trigger_mask() which is also defined in traps.c for SMP. This adds an extra layer of function call / stack push when preempt_disable needs to call other functions, however in the non-preemptive SMP case it should be about as fast, as it was already calling the get_trigger_mask() function which is now used inline.
