This is to enable RoCE on Broadcom's 57500 series of adapters.
Patch 0001, 0002 and 0003 are handing the control path changes.
Patch 0004 and 0005 are related to kernel space fast path.
Patch 0006 handles the user-kernel ABI changes. Patch 0007 is
to enable RoCE driver load on next gen chips.

This patch series requires a patch from Linus git:
commit 78793afbb0b9 ("bnxt_en: Increase context memory allocations on
                      57500 chips for RDMA.")

Changelog:
V3->V4
rebased the series to the tip of for-next.
Patch 0002:
	- dropped use of __iowrite64_copy, use writeq instead.
Patch 0006:
	- use __aligned_u64 instead of __u64.
	- fix sizeof(resp) when copying response to user.
V2->V3
Patch 0006:
	- Implemented the comp_mask approach instead of changing the
	  ABI version number.
V1->V2
Rebased the series to the tip of for-next and fixed widespread
code alignment.
Patch 0001:
        - Replace chip_ctx pointer with static member in bnxt_re_dev
	  structure.
Patch 0002:
        - Fixed kbuild error on i386 arch. Using "depends on 64BIT"
        - Removed wmb before calling writeq in db-ring functions
Patch 0003:
        - Fixed typo in the commit message
Patch 0004:
        - Removed endian-ness fix from feature series.
Patch 0005:
        - Fixed code formatting issues
Patch 0006:
        - Implemented ABI range check as suggested by Jason and Leon
