- In case of suspend lockups it's nice to know it happened in nouveau.

[PATCH 1/3] drm/nouveau: change channel regs mapping to ioremap
Use ioremap() for mapping the channel user regs (that are never exposed
to user space) instead of drm_addmap().
This removes the last use cases of drm_addmap/drm_rmmap from Nouveau.

[PATCH 1/6] drm/nouveau: bo read/write wrappers for nv04_crtc.c
Introduce accessors for TTM buffer object memory that has been mapped
into the kernel virtual address space or as IO memory. IO memory needs
to be accessed via special accessor functions, not by dereferencing the
iomem cookie. The wrappers hide the details of 32-bit access and honour
the TTM map type.
nv04_crtc_cursor_set() is changed to use the new wrappers. 'cursor' is
