[0/3] drm/ttm: Reservation object individualization update

Message

A couple of patches to modify the individualizing somewhat:

The motivation is that we run into trouble with the xe driver doing the
resv individualization in a clean way, having to grab the vm-wide sleeping
lock in a close- or release path which isn't really optimal. While
addressing that, some fly-by cleanups.

Patch 1: Makes sure the bulk move is removed at individualizing time, which is
convenient since we have all required locks.

Patch 2: Individualize even if fence copying fails.

Patch 3: Use a define instead of open-coded timeout


Thomas Hellström (3):
  drm/ttm: Clear the buffer object bulk move at individualize time
  drm/ttm: Clean up bo individualizing somewhat
  drm/ttm: Use a define for the resv wait timeout
