Subject: [PATCH 00/10] drm: use idr_init_base() over idr_init() if applicable

From: Danilo Krummrich <dakr@...hat.com>

This patch series initializes IDRs with idr_init_base(&idr, 1) rather than
idr_init(&idr) in case for the particular IDR no IDs < 1 are ever requested -
this avoids unnecessary tree walks.

Danilo Krummrich (10):
  drm/amdgpu: use idr_init_base() to initialize mgr->ctx_handles
  drm/amdgpu: use idr_init_base() to initialize fpriv->bo_list_handles
  drm: use idr_init_base() to initialize master->magic_map
  drm: use idr_init_base() to initialize master->lessee_idr
  drm: use idr_init_base() to initialize mode_config.object_idr
  drm: use idr_init_base() to initialize mode_config.tile_idr
  drm/sis: use idr_init_base() to initialize dev_priv->object_idr
  drm/v3d: use idr_init_base() to initialize v3d_priv->perfmon.idr
  drm/via: use idr_init_base() to initialize dev_priv->object_idr
  drm/todo: remove task for idr_init_base()
