Register accesses are always 4bytes, accidently this was changed to
a void pointer whwqich badly breaks 64bit archs when running on top
of svga3.

Change
2ef4fb92363c ("drm/vmwgfx: Make sure bo's are unpinned before putting them back")
caused a conflict in one of the drm trees and the merge commit
68a32ba14177 ("Merge tag 'drm-next-2021-04-28' of git://anongit.freedesktop.org/drm/drm")
accidently re-added code that the original change was removing.
Fixed by removing the incorrect buffer unpin - it has already been unpinned
two lines above.

When the comment needs to state explicitly that this

is named rather badly.
Rename the function and use rcu_dereference_check(), this

The allocation of fifo is lacking an allocation failure check, so
fix this by adding one.
In the case where fifo->static_buffer fails to be allocated the
error return path neglects to kfree the fifo object. Fix this by
adding in the missing kfree.
Kudos to Dan Carpenter for spotting the missing kzalloc failure
check.

include using MMIO for register accesses instead of ioports,
deprecating the FIFO MMIO and removing a lot of the old and
legacy functionality. SVGA3 doesn't support guest backed

Now since Christian reworked TTM to always keep objects on the LRU
list unless they are pinned we shouldn't need the reservation
semaphore. It makes the driver code a lot cleaner, especially
because it was a little hard to reason when and where the

In cases where the dirty linear memory range spans multiple sample sheets
in a surface, the dirty surface region is incorrectly computed.
To do this correctly and in an optimized fashion we would have to compute
the dirty region of each sample sheet and compute the union of those
regions.
But assuming that cpu writing to a multisample surface is rather a corner
case than a common case, just set the dirty region to the full surface.

SVGA_REG_ENABLE is a register name, and SVGA_REG_ENABLE_(ENABLE|
DISABLE|HIDE) are its valid values. We were incorrectly setting
the register value to itself. This happened to work because
the SVGA_REG_ENABLE is happens to to be the same value as
SVGA_REG_ENABLE_ENABLE, but is still semantically incorrect.

idr_init() uses base 0 which is an invalid identifier for this driver.
The idr_alloc for this driver uses 1 as start value for ID range. The
new function idr_init_base allows IDR to set the ID lookup from base 1.
This avoids all lookups that otherwise starts from 0 since 0 is always
unused / available.

During cotable resize we pin the backup buffer to make sure the
trylock doesn't fail. We were never unpinning the backup buffer
resulting in every subsequent cotable resize trying to release a
pinned bo. After we copy the old backup to the new we can release
the pin.
Mob's are always pinned so we just have to make sure we unpin
them before releasing them.

We were not correctly unpinning no longer needed buffers. In particular
vmw_buffer_object, which is internally often pinned on creation wasn't
unpinned on destruction and none of the internal MOB buffers were
unpinned before being put back. Technically this existed for a
long time but commit 57fcd550eb15 ("drm/ttm: Warn on pinning without
holding a reference") introduced a WARN_ON which was filling up the
kernel logs rather quickly.
Quite frankly internal usage of vmw_buffer_object and in general
pinning needs to be refactored in vmwgfx but for now this makes
it work.

We should advertise the reworked fifo/cmd handling and huge pages
support. Also while bumping the version number lets cleanup
the logging, there's no point in logging whether we're atomic
(we always are) or what repo we use (it's always in kernel now).

Many drivers reference the plane->state pointer in order to get the
current plane state in their atomic_update or atomic_disable hooks,
which would be the new plane state in the global atomic state since
_swap_state happened when those hooks are run.
Use the drm_atomic_get_new_plane_state helper to get that state to make it
more obvious.
This was made using the coccinelle script below:

The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Let's convert the remaining helpers to provide a consistent interface,
this time with the planes atomic_update and atomic_disable.
The conversion was done using the coccinelle script below, built tested on
