drm/virtio: Use IDAs more efficiently

2018-11-14T11:50:34+00:00

0-based IDAs are more efficient than any other base.  Convert the
1-based IDAs to be 0-based.

drm/virtio: Handle context ID allocation errors

2018-10-29T21:50:55+00:00

It is possible to run out of memory while allocating IDs.  The current
code would create a context with an invalid ID; change it to return
-ENOMEM to userspace.

drm/virtio: Replace IDRs with IDAs

2018-10-29T21:50:55+00:00

These IDRs were only being used to allocate unique numbers, not to look
up pointers, so they can use the more space-efficient IDA instead.

virtgpu: remove redundant task_comm copying

2017-11-10T11:45:35+00:00

Remove redundant task name copying because:

1. task->comm is already NUL-terminated
2. virtio_gpu_context_create() trims passed dbgname anyway
