Make sure we don't leak half-initialized fences outside the driver.

No need to do the reservation dance,
we can just wait on the fence directly.

With this gem and ttm will use the same reservation object,
so mixing and matching ttm / gem reservation helpers should
work fine.

Use drm_gem_reservation_object_wait() in virtio_gpu_wait_ioctl().
This also makes the ioctl run lockless.
v5: handle lookup failure.
v2: use reservation_object_test_signaled_rcu for VIRTGPU_WAIT_NOWAIT.

Call reservation_object_* directly instead
of using ttm_bo_{reserve,unreserve}.
v4: check for EINTR only.
v3: check for EINTR too.

Thin wrapper around virtio_gpu_object_create(),
but calling that directly works equally well.

Rework fencing workflow, starting with virtio_gpu_execbuffer_ioctl.
Stop using ttm helpers, use the virtio_gpu_array_* helpers (which work
on the reservation objects directly) instead.
Also store the object array in struct virtio_gpu_vbuffer, so we
explicitly keep a reference of all buffers used
Switch to the virtio_gpu_array_* helper workflow.

When not using large TLBs, the IMMR region is still
mapped as a whole block in the FIXMAP area.
Do not remove pages mapped in the FIXMAP region when
initialising paging.
Properly report that the IMMR region is block-mapped even
when not using large TLBs.

Commit d2f15e0979ee ("powerpc/32: always populate page tables for
Abatron BDI.") wrongly sets page tables for any PPC32 for using BDI,
and does't update them after init (remove RX on init section, set
text and rodata read-only)
Only the 8xx requires page tables to be populated for using the BDI.
Just cleanup, no logic change.
