[PATCH v4 rdma-next 0/3] RDMA/qedr: Use the doorbell overflow recovery mechanism for RDMA

[Michal Kalderon <michal.kalderon@marvell.com>]

This patch series used the doorbell overflow recovery mechanism
introduced in
commit 36907cd5cd72 ("qed: Add doorbell overflow recovery mechanism")
for rdma ( RoCE and iWARP )

rdma-core pull request #493

Changes from V3:
- Remove casts from void to u8. Pointer arithmetic can be done on void
- rebase to tip of rdma-next

Changes from V2:
- Don't use long-lived kmap. Instead use user-trigger mmap for the
  doorbell recovery entries.
- Modify dpi_addr to be denoted with __iomem and avoid redundant
  casts

Changes from V1:
- call kmap to map virtual address into kernel space
- modify db_rec_delete to be void
- remove some cpu_to_le16 that were added to previous patch which are
  correct but not related to the overflow recovery mechanism. Will be
  submitted as part of a different patch
