drm/nouveau: handle same-fb page flips
It's questionable use case, but weston/wayland already relies on this
behaviour, and other drivers don't care about it, so it's a matter of
compatibility. Without it, process invoking such page flip hangs in
unkillable state, trying to reserve the same buffer twice.

drm/nouveau/pm: do not stop reclocking if failing to set the fan speed
With the introduction of fan management modes, fan may not be drivable.
We should allow reclocking nonetheless.
This return was stupid to begin with since it may have left the card
in an intermediate state (clocks corresponding to a perflvl and voltage
corresponding to another one). The reclocking code will need to be
rewritten in a near-future in order to provide a better error handling.

drm/nv41/vm: fix and enable use of "real" pciegart
Hopefully fixed the tlb flush timeout issue. Was able to observe this
condition occur occasionally, and it appears the binary driver doesn't
wait on the old condition either..
Should give 39-bit DMA addressing on the relevant chipsets.

drm/nouveau/therm: add support for fan-control modes
For now, only 2 control modes are available:
- NONE: The fan is never touched (default)
- MANUAL: The fan is set to the user-defined fan speed (pwm1)
This patch introduces a distinction between ptherm internal fan management
and external fan management. The latter is bound to respect the fan mode
while the first can still select the speed it wants unless the NONE mode
is selected. This is important for automatic fan management.

Further patches will fix the actual "driver" code and add new features.

v3: add a missing include

- fixed set_defaults() to allow min_duty < 30 (thermal table will
override this if it's actually necessary)

thermal table entry to provide us the value.

drm/nouveau/core: have fifo store a unique context identifier at attach time
This value will match something that's easily available from the engine IRQ
handlers, and used to lookup the relevant context.
Since the changes in how this is done on each generation match when the
major PFIFO changes happened, fifo is responsible for calculating the
correct value to avoid duplicating the same code among many engine modules.

drm/nouveau: port all engines to new engine module format
This is a HUGE commit, but it's not nearly as bad as it looks - any problems
can be isolated to a particular chipset and engine combination. It was
simply too difficult to port each one at a time, the compat layers are
*already* ridiculous.
Most of the changes here are simply to the glue, the process for each of the
engine modules was to start with a standard skeleton and copy+paste the old
code into the appropriate places, fixing up variable names etc as needed.
