parser->chunks[.].kpage[.] is not always kmalloc-ed
by the parser initialization, so parser_fini should
not try to kfree it if it didn't allocate it.
This patch fixes a kernel oops that can be provoked
in UMS mode.

Fixes regression introduced in commit 861d2107
"drm/nouveau/fb: merge fb/vram and port to subdev interfaces"
nv50_fb_vram_{new,del} functions were changed to use
nouveau_subdev->mutex instead of the old nouveau_mm->mutex.
nvc0_fb_vram_new still uses the nouveau_mm->mutex, but nvc0 doesn't
have its own fb_vram_del function, using nv50_fb_vram_del instead.
Because of this, on nvc0 a different mutex ends up being used to protect
additions and deletions to the same list.
This patch is a -stable candidate for 3.7.

Fixes regression introduced in commit 70790f4f
"drm/nouveau/clock: pull in the implementation from all over the place"
When code was moved from nv50_crtc_set_clock to nvc0_clock_pll_set,
the PLLs it is used for got limited to only the first two VPLLs.
nv50_crtc_set_clock was only called to change VPLLs, so it didn't
limit what it was used for in any way. Since nvc0_clock_pll_set is
used for all PLLs, it has to specify which PLLs the code is used for,
and only listed the first two VPLLs.

Since commit 5e120f6e4b3f35b741c5445dfc755f50128c3c44 "drm/nouveau/fence:
convert to exec engine, and improve channel sync" nouveau fence sync
implementation for nv17-50 and nvc0+ started to rely on state of fence buffer
left by previous sync operation. But as pinned bo's (where fence state is
stored) are not saved+restored across suspend/resume, we need to do it
manually.
nvc0+ was fixed by commit d6ba6d215a538a58f0f0026f0961b0b9125e8042
"drm/nvc0/fence: restore pre-suspend fence buffer context on resume".

Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate
from create/destroy") started to call display init routines on pre-nv50
hardware on module load. But LVDS init code sets driver state in a way
which prevents modesetting code from operating properly.
nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to
NV_DPMS_CLEARED.
drm_crtc_helper_set_mode
nv04_dfp_prepare
nv04_lvds_dpms(DRM_MODE_DPMS_OFF)
nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly
assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too,
so it skips calling some crucial lvds scripts.

This fix was put in place to fix a bug where the eDP panel on certain
laptops fails to respond over the aux channel after suspend.
It appears that on some systems (Dell M6600, with LVDS panel) there's a
very bad interaction with the eDP init table that causes the SOR to get
very confused and not drive the panel correctly, leading to bleed.
A DPMS off/on cycle is enough to bring it back, but, this will avoid the
problem by not touching the panel GPIOs at times we're not meant to.

This partially reverts
commit 6c085a728cf000ac1865d66f8c9b52935558b328
Author: Chris Wilson <chris@chris-wilson.co.uk>

drm/i915: Track unbound pages
Closer inspection of that patch revealed a bunch of unrelated changes
in the shrinker:
- The shrinker count is now in pages instead of objects.
- For counting the shrinkable objects the old code only looked at the
inactive list, the new code looks at all bounds objects (including
pinned ones). That is obviously in addition to the new unbound list.
- The shrinker cound is no longer scaled with
sysctl_vfs_cache_pressure. Note though that with the default tuning
value of vfs_cache_pressue = 100 this doesn't affect the shrinker
behaviour.
- When actually shrinking objects, the old code first dropped
purgeable objects, then normal (inactive) objects. Only then did it,
in a last-ditch effort idle the gpu and evict everything. The new
code omits the intermediate step of evicting normal inactive
objects.
Safe for the first change, which seems benign, and the shrinker count
scaling, which is a bit a different story, the endresult of all these
changes is that the shrinker is _much_ more likely to fall back to the
last-ditch resort of idling the gpu and evicting everything. The old
code could only do that if something else evicted lots of objects
meanwhile (since without any other changes the nr_to_scan will be
smaller than the object count).
Reverting the vfs_cache_pressure behaviour itself is a bit bogus: Only
dentry/inode object caches should scale their shrinker counts with
vfs_cache_pressure. Originally I've had that change reverted, too. But
Chris Wilson insisted that it's too bogus and shouldn't again see the
light of day.
Hence revert all these other changes and restore the old shrinker
behaviour, with the minor adjustment that we now first scan the
unbound list, then the inactive list for each object category
(purgeable or normal).
A similar patch has been tested by a few people affected by the gen4/5
hangs which started to appear in 3.7, which some people bisected to
the "drm/i915: Track unbound pages" commit. But just disabling the
unbound logic alone didn't change things at all.
Note that this patch doesn't fix the referenced bugs, it only hides
the underlying bug(s) well enough to restore pre-3.7 behaviour. The
key to achieve that is to massively reduce the likelyhood of going
into a full gpu stall and evicting everything.
v2: Reword commit message a bit, taking Chris Wilson's comment into
account.
v3: On Chris Wilson's insistency, do not reinstate the rather bogus
vfs_cache_pressure change.

drm: mm: track free areas implicitly
which swaps the end address for size (with a potential overflow) and
effectively causes the eviction code to clobber almost all earlier
buffers above the evictee.
v2: Check the original hole not the adjusted as the coloring may confuse
us when later searching for the overlapping nodes. Also make sure that
we do apply the range restriction and color adjustment in the same
order for both scanning, searching and insertion.
v3: Send the version that was actually tested.
Note that this seems to be ducttape of decent quality ot paper over
some of our unbind related gpu hangs reported since 3.7. It is not
fully effective though, and certainly doesn't fix the underlying bug.

Since commit 8871e99f89b7 ('asus-laptop: HRWS/HWRS typo'), module
initialisation is very slow on the Asus UL30A. The HWRS method takes
about 12 seconds to run, and subsequent initialisation also seems to
be delayed. Since we don't really need the result, don't bother
calling it on init. Those who are curious can still get the result
through the 'infos' device attribute.
Update the comment about HWRS in show_infos().

SN06 in some cases returns an Integer instead of a buffer. While the
code handling the return value was trying to cope with the difference,
the memcpy call was not making any difference between the two types of
acpi_object union. This regression was introduced in 3.5.
While there also rework the return value logic to improve readability.

KEY_TOUCHPAD_TOOGLE key is for notice userland change touchpad state
via xf86-input-synaptics on the machine that don't toggle touchpad in
hardware. But, acer laptop actually toggle touchpad in hardware.
So, this patch change to emit KEY_TOUCHPAD_ON/OFF key when acer-wmi grab
device state of touchpad.

This patch adds user eqs exception hooks for async page fault page not
present code path, to exit the user eqs and re-enter it as necessary.
Async page fault is different from other exceptions that it may be
triggered from idle process, so we still need rcu_irq_enter() and
rcu_irq_exit() to exit cpu idle eqs when needed, to protect the code
that needs use rcu.
As Frederic pointed out it would be safest and simplest to protect the
whole kvm_async_pf_task_wait(). Otherwise, "we need to check all the
code there deeply for potential RCU uses and ensure it will never be
extended later to use RCU.".
However, We'd better re-enter the cpu idle eqs if we get the exception
in cpu idle eqs, by calling rcu_irq_exit() before native_safe_halt().
So the patch does what Frederic suggested for rcu_irq_*() API usage
here, except that I moved the rcu_irq_*() pair originally in
do_async_page_fault() into kvm_async_pf_task_wait().
That's because, I think it's better to have rcu_irq_*() pairs to be in
one function ( rcu_irq_exit() after rcu_irq_enter() ), especially here,
kvm_async_pf_task_wait() has other callers, which might cause
rcu_irq_exit() be called without a matching rcu_irq_enter() before it,
which is illegal if the cpu happens to be in rcu idle state.

Pull tracing regression fix from Steven Rostedt:
"A change that came in this merge window broke the writing to the
trace_options file. It causes garbage to be read during the compare
of option names, and breaks setting options via the trace_options
file, although options can still be set via the options/<option>
files."

The latest change to allow trace options to be set on the command
line also broke the trace_options file.
The zeroing of the last byte of the option name that is echoed into
the trace_option file was removed with the consolidation of some
of the code. The compare between the option and what was written to
the trace_options file fails because the string holding the data
written doesn't terminate with a null character.
A zero needs to be added to the end of the string copied from
user space.

Partially revert ae289dc1f "s390/3215: fix tty close handling", since this
leads sometimes to hanging agetty processes and therefore systems that get
stuck while starting.
This was magically fixed (bisected) by a common code patch from Alan Cox:
36b3c070 "tty: Move the handling of the tty release logic", however it was
unrelated.
Since the removed code worked for a decade, nobody knows anymore why it was
in there in the first place and debugging the observed hang is non-trivial
(at least for me :) ), let's just re-add the removed code before we see
other side effects.
