Some drivers don't have real ->create_handle callbacks.

- cirrus/ast/mga200: Returns either 0 or -EINVAL.

- udl: Didn't even bother with a callback, leading to a nice
  userspace-triggerable OOPS.

- vmwgfx: This driver bothered with an implementation to return 0 as
  the handle (which is the canonical no-obj gem handle).

All have in common that ->create_handle doesn't really make too much
sense for them - that ioctl is used only for seamless fb takeover in
the radeon/nouveau/i915 ddx drivers. So allow drivers to not implement
this and return a consistent -ENODEV.

... by moving the bo_pin/bo_unpin manipulation of the pin_refcount
under the protection of the ttm reservation lock. pin/unpin seems
to get called from all over the place, so atm this is completely racy.

After this patch there are only a few places in cleanup functions
left which access ->pin_refcount without locking. But I'm hoping that
those are safe and some other code invariant guarantees that this
won't blow up.

In any case, I only need to fix up pin/unpin to make ->pageflip work
safely, so let's keep it at that.

Add a comment to the header to explain the new locking rule.

With per-crtc locks modeset operations can run in parallel, and the
cursor code uses the device-global evo master channel for hw frobbing.
But the pageflip code can also sync with the master under some
circumstances. Hence just wrap things up in a mutex to ensure that
pushbuf access doesn't intermingle.

The approach here is a bit overkill since the per-crtc channels used
to schedule the pageflips could probably be used without this pushbuf
locking, but I'm not familiar enough with the nouveau codebase to be
sure of that.

Doing this within the fb->destroy callback leads to a locking
nightmare. And all other drm drivers that restore the fbcon do
it in lastclose, too.

With this adjustments all fb->destroy callbacks optionally drop
references to any gem objects used as backing storage, call
drm_framebuffer_cleanup and then kfree the struct. Which nicely
simplifies the locking for framebuffer unreferencing and freeing,
since this doesn't require that we hold the mode_config lock. A
slight exception is the vmwgfx surface backed framebuffer, it also
calls drm_master_put and removes the object from a device-private
framebuffer list. Both seem to have solid locking in place already.

Conclusion is that now it is no longer required to hold the
mode_config lock while freeing a framebuffer.

v2: Drop the corresponding mutex_lock WARN check from
drm_framebuffer_unreference.

v3: Use just the mode_config lock not modeset_lock_all, due to patch
reordering.

vmwgfx has an oddity, when failing to reference the surface it'll
return 0, since that's what the successfull drm_framebuffer_init will
leave behind in ret. Fix this up by returning -EINVAL.

With more fine-grained locking we can no longer rely on the big
mode_config lock to prevent concurrent access to mode resources
like framebuffers. Instead a framebuffer becomes accessible to
other threads as soon as it is added to the relevant lookup
structures. Hence it needs to be fully set up by the time drivers
call drm_framebuffer_init.

This patch here is the drivers part of that reorg. Nothing really fancy
going on safe for three special cases.

- exynos needs to be careful to properly unref all handles.
- nouveau gets a resource leak fixed for free: one of the error
  cases didn't cleanup the framebuffer, which is now moot since
  the framebuffer is only registered once it is fully set up.
- vmwgfx requires a slight reordering of operations, I'm hoping I didn't
  break anything (but it's refcount management only, so should be safe).

v2: Split out exynos, since it's a bit more hairy than expected.

v3: Drop bogus cirrus hunk noticed by Richard Wilbur.

v4: Split out vmwgfx since there's a small change in return values.

- config_cleanup was confused: It claimed that callers need to hold
  the modeset lock, but the connector|encoder_cleanup helpers grabbed
  that themselves (note that crtc_cleanup did _not_ grab the modeset
  lock). Which resulted in all drivers _not_ hodling the lock. Since
  this is for single-threaded cleanup code, drop the requirement from
  docs and also drop the lock_grabbing from all _cleanup functions.

- Kill the LOCKING section in the doctype, since clearly we're not
  good enough to keep them up-to-date. And misleading locking
  documentation is worse than useless (see e.g. the comment in the
  vmgfx driver about the cleanup mess). And since for most functions
  the very first line either grabs the lock or has a WARN_ON(!locked)
  the documentation doesn't really add anything.

- Instead put in some effort into explaining the only two special
  cases a bit better: config_init and config_cleanup are both called
  from single-threaded setup/teardown code, so don't do any locking.
  It's the driver's job though to enforce this.

- Where lacking, add a WARN_ON(!is_locked). Not many places though,
  since locking around fbdev setup/teardown is through-roughly screwed
  up, and so will break almost every single WARN annotation I've tried
  to add.

- Add a drm_modeset_is_locked helper - the Grate Modset Locking Rework
  will use the compiler to assist in the big reorg by renaming the
  mode lock, so start encapsulating things. Unfortunately this ended
  up in the "wrong" header file since it needs the definition of
  struct drm_device.

v2: Drop most WARNS again - we hit them all over the place, mostly in
the setup and teardown sequences. And trying to fix it up leads to
nice deadlocks, since the locking in the setup code is really
inconsistent.

XFS: Assertion failed: (char *)dup - (char *)hdr == be16_to_cpu(*xfs_dir2_data_unused_tag_p(dup)), file: fs/xfs/xfs_dir2_data.c, line: 828

Upon further digging, the tag found by xfs_dir2_data_unused_tag_p(dup)
contained "2" and not the proper offset, and I found that this value was
changed after the memmoves under "Use a stale leaf for our new entry."
in xfs_dir2_block_addname(), i.e.

                        memmove(&blp[mid + 1], &blp[mid],
                                (highstale - mid) * sizeof(*blp));

overwrote it.

What has happened is that the previous call to xfs_dir2_block_compact()
has rearranged things; it changes btp->count as well as the
blp array.  So after we make that call, we must recalculate the
proper pointer to the leaf entries by making another call to
xfs_dir2_block_leaf_p().

If the default iosched is built as module, the kernel may deadlock
while trying to load the iosched module on device probe if the probing
was running off async.  This is because async_synchronize_full() at
the end of module init ends up waiting for the async job which
initiated the module loading.

 async A				modprobe

 1. finds a device
 2. registers the block device
 3. request_module(default iosched)
					4. modprobe in userland
					5. load and init module
					6. async_synchronize_full()

Async A waits for modprobe to finish in request_module() and modprobe
waits for async A to finish in async_synchronize_full().

Because there's no easy to track dependency once control goes out to
userland, implementing properly nested flushing is difficult.  For
now, make module init perform async_synchronize_full() iff module init
has queued async jobs as suggested by Linus.

This avoids the described deadlock because iosched module doesn't use
async and thus wouldn't invoke async_synchronize_full().  This is
hacky and incomplete.  It will deadlock if async module loading nests;
however, this works around the known problem case and seems to be the
best of bad options.

The way SEI was called with nt2 and nt0 consecutive broke the nt0
stuff used for channel subsystem notifications.

The reason why this was broken with the mentioned patch is that you
cannot selectively disable type 0 notifications (so even when asked
for type 2 only, type 0 could be presented).

The way to do it is to tell SEI which types of notification you can
process and -this is the important part- look at the SEI result which
notification type you actually received.

Converting a 64 Bit TOD format value to nanoseconds means that the value
must be divided by 4.096. In order to achieve that we multiply with 125
and divide by 512.
When used within sched_clock() this triggers an overflow after appr.
417 days. Resulting in a sched_clock() return value that is much smaller
than previously and therefore may cause all sort of weird things in
subsystems that rely on a monotonic sched_clock() behaviour.

To fix this implement a tod_to_ns() helper function which converts TOD
values without overflow and call this function from both places that
open coded the conversion: sched_clock() and kvm_s390_handle_wait().

When "alsactl restore" is performed on HDMI codecs, it tries to
restore the channel map value since the channel map controls are
writable.  But hdmi_chmap_ctl_put() returns -EBADFD when no PCM stream
is assigned yet, and this results in an error message from alsactl.
Although the error is harmless, it's certainly ugly and can be
regarded as a regression.

As a workaround, this patch changes the return code in such a case to
be zero for making others happy.  (A slight excuse is: when the chmap
is changed through the proper alsa-lib API, the PCM status is checked
there anyway, so we don't have to be too strict in the kernel side.)

We realized that the power usage field is never filled and when it
is filled for tegra, the power_specified flag is not set causing all
of these values to be reset when the driver is initialized with
set_power_state().

However, the power_specified flag can be simply removed under the
assumption that the states are always backward sorted, which is the
case with the current code.

This change allows the menu governor select function and the
cpuidle_play_dead() to be simplified.  Moreover, the
set_power_states() function can removed as it does not make sense
any more.

Drop the power_specified flag from struct cpuidle_driver and make
the related changes as described above.

As a consequence, this also fixes the bug where on the dynamic
C-states system, the power fields are not initialized.
