After a maddening 2 days sifting through perf minutia I found it --

That messes up the sample sorting such that synthesized guest maps are

wireless: Save original maximum regulatory transmission power for the calucation of the local maximum transmit pow
changed the way we calculate chan->max_power as min(chan->max_power,
chan->max_reg_power). That broke rt2x00 (and perhaps some other
drivers) that do not set chan->max_power. It is not so easy to fix this
problem correctly in rt2x00.
According to commit eccc068e8 changelog, change claim only to save
maximum regulatory power - changing setting of chan->max_power was side
effect. This patch restore previous calculations of chan->max_power and
do not touch chan->max_reg_power.

We've got a bug report about the silent output from the headphone on a

D3 state on the DAC for the headphone output. The bug is triggered by
the incomplete check for this DAC in set_widgets_power_state_vt1718S().
It checks only the connectivity of the primary output (0x27) but
doesn't consider the path from the headphone pin (0x28).
Now this patch fixes the problem by checking both pins for DAC 0x0b.

LVDS is the first output where dpms on/off and prepare/commit don't
perfectly match. Now the idea behind this special case seems to be
that for simple resolution changes on the LVDS we don't need to stop
the pipe, because (at least on newer chips) we can adjust the panel
fitter on the fly.
There are a few problems with the current code though:
- We still stop and restart the pipe unconditionally, because the crtc
helper code isn't flexible enough.
- We show some ugly flickering, especially when changing crtcs (this
the crtc helper would actually take into account, but we don't
implement the encoder->get_crtc callback required to make this work
properly).
So it doesn't even work as advertised. I agree that it would be nice
to do resolution changes on LVDS (and also eDP) whithout blacking the
screen where the panel fitter allows to do that. But imo we should
implement this as a special case a few layers up in the mode set code,
akin to how we already detect simple framebuffer changes (and only
update the required registers with ->mode_set_base).
Until this is all in place, make our lives easier and just rip it out.
Also note that this seems to fix actual bugs with enabling the lvds
output, see:

The issue is that we stale data in the CPU caches, when we come to
swap-out the object, the CPU may short-circuit the reads from those
cacheline and so corrupt the context object.
Secondary, leaving the context object as being marked in the CPU write
domain whilst on the GPU active list is a bad idea and will throw
warnings later.
Note: Thanks to calling set_to_gtt_domain with write = false and not
setting any gpu write domain when putting a context object onto the
active list (when we switch away from it) the set_to_gtt_domain call
won't block.

The touchpad on the Acer Aspire One D250 will report out of range values
in the extreme lower portion of the touchpad. These appear as abrupt
changes in the values reported by the hardware from very low values to
very high values, which can cause unexpected vertical jumps in the
position of the mouse pointer.
What seems to be happening is that the value is wrapping to a two's
compliment negative value of higher resolution than the 13-bit value
reported by the hardware, with the high-order bits being truncated. This
patch adds handling for these values by converting them to the
appropriate negative values.
The only tricky part about this is deciding when to treat a number as
negative. It stands to reason that if out of range values can be
reported on the low end then it could also happen on the high end, so
not all out of range values should be treated as negative. The approach
taken here is to split the difference between the maximum legitimate
value for the axis and the maximum possible value that the hardware can
report, treating values greater than this number as negative and all
other values as positive. This can be tweaked later if hardware is found
that operates outside of these parameters.

With the current state of irq_domain, the reverse map is always updated
when new IRQs get mapped. This means that the irq_find_mapping() function
can be simplified to execute the revmap lookup functions unconditionally
This patch adds lookup functions for the revmaps that don't yet have one
and removes the slow path lookup code path.
v8: Broke out unrelated changes into separate patches. Rebased on Paul's irq
association patches.
v7: Rebased to irqdomain/next for v3.4 and applied before the removal of 'hint'
v6: Remove the slow path entirely. The only place where the slow path
could get called is for a linear mapping if the hwirq number is larger
than the linear revmap size. There shouldn't be any interrupt
controllers that do that.
v5: rewrite to not use a ->revmap() callback. It is simpler, smaller,
safer and faster to open code each of the revmap lookups directly into
irq_find_mapping() via a switch statement.

Setting dev_mapping (pointer to the address_space structure
used for memory mappings) to the address_space of the first
opener's inode and then failing if other openers come in
through a different inode has a few restrictions that are
eliminated by this patch.
If we already have valid dev_mapping and we spot an opener
with different i_node, we force its i_mapping pointer to the
already established address_space structure (first opener's
inode). This will make all mappings from drm device hang off
the same address_space object.
Some benefits (things that now work and didn't work
before) of this patch are:
* user space can mknod and use any number of device
nodes and they will all work fine as long as the major
device number is that of the drm module.
* user space can even remove the first opener's device
nodes and mknod the new one and the applications and
windowing system will still work.
* GPU drivers can safely assume that dev->dev_mapping is
correct address_space and just blindly copy it
into their (private) bdev.dev_mapping

Pull workqueue changes from Tejun Heo:
"There are three major changes.
- WQ_HIGHPRI has been reimplemented so that high priority work items
are served by worker threads with -20 nice value from dedicated
highpri worker pools.
- CPU hotplug support has been reimplemented such that idle workers
are kept across CPU hotplug events. This makes CPU hotplug cheaper
(for PM) and makes the code simpler.
- flush_kthread_work() has been reimplemented so that a work item can
be freed while executing. This removes an annoying behavior
difference between kthread_worker and workqueue."
* 'for-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq:
workqueue: fix spurious CPU locality WARN from process_one_work()
kthread_worker: reimplement flush_kthread_work() to allow freeing the work item being executed
kthread_worker: reorganize to prepare for flush_kthread_work() reimplementation
workqueue: simplify CPU hotplug code
workqueue: remove CPU offline trustee
workqueue: don't butcher idle workers on an offline CPU
workqueue: reimplement CPU online rebinding to handle idle workers
workqueue: drop @bind from create_worker()
workqueue: use mutex for global_cwq manager exclusion
workqueue: ROGUE workers are UNBOUND workers
workqueue: drop CPU_DYING notifier operation
workqueue: perform cpu down operations from low priority cpu_notifier()
workqueue: reimplement WQ_HIGHPRI using a separate worker_pool
workqueue: introduce NR_WORKER_POOLS and for_each_worker_pool()
workqueue: separate out worker_pool flags
workqueue: use @pool instead of @gcwq or @cpu where applicable
workqueue: factor out worker_pool from global_cwq
workqueue: don't use WQ_HIGHPRI for unbound workqueues
Pull misc udf, ext2, ext3, and isofs fixes from Jan Kara:
"Assorted, mostly trivial, fixes for udf, ext2, ext3, and isofs. I'm
on vacation and scarcely checking email since we are expecting baby
any day now but these fixes should be safe to go in and I don't want
to delay them unnecessarily."
* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs:
udf: avoid info leak on export
isofs: avoid info leak on export
udf: Improve table length check to avoid possible overflow
ext3: Check return value of blkdev_issue_flush()
jbd: Check return value of blkdev_issue_flush()
udf: Do not decrement i_blocks when freeing indirect extent block
udf: Fix memory leak when mounting
ext2: cleanup the confused goto label
UDF: Remove unnecessary variable "offset" from udf_fill_inode
udf: stop using s_dirt
ext3: force ro mount if ext3_setup_super() fails
quota: fix checkpatch.pl warning by replacing <asm/uaccess.h> with <linux/uaccess.h>
Pull m68knommu arch update from Greg Ungerer:
"Quite a varied set of changes this time.
- A little more merge cleanup, this time the assembler entry code.
- New sub-architecture support for the ColdFire 5251/5253 and 5441x
CPU families.
- Specific clk support code for the ColdFire 520x and 532x CPU
familes.
- Refactoring of the ColdFire GPIO support.
- PCI bus support for some ColdFire CPUS that have PCI hardware (54xx
family). This showed up a few problems with ColdFire cache,
allocating coherent memory and bi-directional DMA support. Fixes
for those too."
