This series contains various updates to the device definitions handling
and documentation.

The last patch is based on a discussion that came up during the recent
mmap machanism review on list:
https://lore.kernel.org/linux-rdma/20190920133817.GB7095@ziepe.ca/

We no longer delay the free_pages_exact call of mmaped DMA pages, as the
pages won't be freed in case they are still referenced by the vma.

Changelog -
v1->v2: https://lore.kernel.org/linux-rdma/20200114085706.82229-1-galpress@amazon.com/
* Use FIELD_GET and FIELD_PREP for EFA_GET/SET
* Make sure to mask (clear) the field before ORing it with a new value
* Clarify the commit message of the last patch
* Reorder the cleanup in the last commit, entry removal now happens
  first

Gal Pressman (3):
  RDMA/efa: Unified getters/setters for device structs bitmask access
  RDMA/efa: Properly document the interrupt mask register
  RDMA/efa: Do not delay freeing of DMA pages
