[PATCH v4 0/9] drm/nouveau: support for GK20A, cont'd

[Alexandre Courbot]

Latest patches for GK20A, taking comments received for v3 into account.

Changes since v3:
- use only pfn_to_page() and page_to_pfn() in GK20A's FB. These functions
  are present on every arch and the physical address to page frame number
  conversion is also consistently a shift of PAGE_SHIFT. This part will
  probably be replaced by something nicer in the future anyway.
- fixed a warning on 64-bit architectures when printing a dma_addr_t
- tested compilation on x86_64 and ensured there was no error! ;)
- in graph, always use external firmware if no microcode is linked for the
  graph class (instead of only relying on the NvGrUseFW parameter).

Alexandre Courbot (9):
  drm/nouveau/bar: only ioremap BAR3 if it exists
  drm/nouveau/bar/nvc0: support chips without BAR3
  drm/nouveau/ibus: add GK20A support
  drm/nouveau/fb: add GK20A support
  drm/nouveau/fifo: add GK20A support
  drm/nouveau/graph: enable when using external fw
  drm/nouveau/graph: pad firmware code at load time
  drm/nouveau/graph: add GK20A support
  drm/nouveau: support for probing GK20A
