a38eab52ff drivers: gpu: Move prototype declaration to header file radeon_mode.h
Move prototype declaration of functions radeon_add_atom_connector() and
radeon_add_legacy_connector() to header file drm/radeon/radeon_mode.h
because  they are used by more than one file.

This eliminates the following warning in drm/radeon/radeon_connectors.c:
drivers/gpu/drm/radeon/radeon_connectors.c:1588:1: warning: no previous prototype for ‘radeon_add_atom_connector’ [-Wmissing-prototypes]
drivers/gpu/drm/radeon/radeon_connectors.c:2020:1: warning: no previous prototype for ‘radeon_add_legacy_connector’ [-Wmissing-prototypes]

6c7bccea39 drm/radeon/pm: move pm handling into the asic specific code
We need more control over the ordering of dpm init with
respect to the rest of the asic.  Specifically, the SMC
has to be initialized before the rlc and cg/pg.  The pm
code currently initializes late in the driver, but we need
it to happen much earlier so move pm handling into the asic
specific callbacks.

This makes dpm more reliable and makes clockgating work
properly on CIK parts and should help on SI parts as well.

 Use memdup_user rather than duplicating its implementation
 This is a little bit restricted to reduce false positives

99c09e745d drm: remove dev->vma_count
This is just used for a debugfs file, and we can easily reconstruct
this number by just walking the list twice. Which isn't really bad for
a debugfs file anyway.

So let's rip this out.

There's the other issue that the dev->vmalist itself is a bit useless,
since that can be reconstructed with all the memory mapping
information from proc. But remove that is a different topic entirely.

5952fba501 drm: Kill file_priv->ioctl_count tracking
It's racy, and it's only used in debugfs. There are simpler ways to
know whether something is going on (like looking at dmesg with full
debugging enabled). And they're all much more useful.

So let's just rip this out.

43d1337cbe drm: rip out dev->ioctl_count tracking
Now dev->ioctl_count tries to prevent the device from disappearing if
it's still in use. And if we'd actually need this code it would be
hopelessly racy and broken.

But luckily the vfs already takes care of this. So we can just rip it
out.
