The ProcessAuxChannel table on some rv635 boards assumes
the divmul members are initialized to 0 otherwise we get
an invalid fb offset since it has a bad mask set when
setting the fb base. While here initialize all the
atom interpretor elements to 0.

Commit 0108bc808107: "drm/nouveau: do not allow negative sizes for now" broke
older nvidia gpu's that lack a vm. Add an explicit check to handle this.

Commits 0a9e2b959 (drm/nvd0/disp: move HDA codec setup to core) and
a4feaf4ea (drm/nva3/disp: move hda codec handling to core) moved code
around but neglected to fill data up to 0x60 as before. This caused
/proc/asound/cardN/eld#3.0 to show eld_valid as 0. With this patch, that
file is again populated with the correct data.

Since the original merge of nouveau to upstream kernel, we were assuming
that nv90 (and later) cards have 32 lines.
Based on mmio traces of the binary driver, as well as PBUS error messages
during read/write of the e070/e074 registers, we can conclude that nv92
has only 16 lines whereas nv94 (and later) cards have 32.

Kernel panic caused by list corruption in ltcg seems to indicate a
concurrency issue.
Take mutex of pfb like nv50_ram_put() to eliminate concurrency.

The current logic is wrong since we send fw->size >> 8 to the
card. Rounding the size up by 0x100 and 0x1000 didn't seem to help,
the card still hung, so go back to what the blob does -- 0x40000.

and enable reclocking by default when dpm is enabled.

Disable cac setup on SI for now since it causes
strange performance level restrictions on certain
cards. I suspect there may be issues with some of
the 64 bit fixed point double emulation that is used
to set up those parameters. I need to double check
the math before this can be re-enabled.

Coarse grain clockgating causes problems with reclocking on
some cards and powergating (verde only) causes problems with
ring initialization. The proper fix (restructuring the init
sequences) is too invasive for 3.11 so just disable them for
now.

We need to set the dto source before setting the
dividers otherwise we may get stability problems
with the dto leading to audio playback problems.

free_irq() expects the same device identity that was passed to
corresponding request_irq(), otherwise the IRQ is not freed.

ARRAY_SIZE() to int to silence the build warning.

If an attempt is made to unbind a device from vfio-pci while that
device is in use, the request is blocked until the device becomes
unused. Unfortunately, that unbind path still grabs the device_lock,
which certain things like __pci_reset_function() also want to take.
This means we need to try to acquire the locks ourselves and use the
pre-locked version, __pci_reset_function_locked().

BUS_NOTIFY_DEL_DEVICE triggers IOMMU drivers to remove devices from
their iommu group, but there's really nothing we can do about it at
this point. If the device is in use, then the vfio sub-driver will
block the device_del from completing until it's released. If the
device is not in use or not owned by a vfio sub-driver, then we
really don't care that it's being removed.
The current code can be triggered just by unloading an sr-iov driver
(ex. igb) while the VFs are attached to vfio-pci because it makes an
incorrect assumption about the ordering of driver remove callbacks
vs the DEL_DEVICE notification.

vmpressure is called synchronously from reclaim where the target_memcg
is guaranteed to be alive but the eventfd is signaled from the work
queue context. This means that memcg (along with vmpressure structure
which is embedded into it) might go away while the work item is pending
which would result in use-after-release bug.
We have two possible ways how to fix this. Either vmpressure pins memcg
before it schedules vmpr->work and unpin it in vmpressure_work_fn or
explicitely flush the work item from the css_offline context (as
suggested by Tejun).
This patch implements the later one and it introduces vmpressure_cleanup
which flushes the vmpressure work queue item item. It hooks into
mem_cgroup_css_offline after the memcg itself is cleaned up.
