Pull rdma updates from Jason Gunthorpe:
"Usual wide collection of unrelated items in drivers:
- Driver bug fixes and treewide cleanups in hfi1, siw, qib, mlx5,
rxe, usnic, usnic, bnxt_re, ocrdma, iser:
- remove unnecessary NULL checks
- kmap obsolescence
- pci_enable_pcie_error_reporting() obsolescence
- unused variables and macros
- trace event related warnings
- casting warnings
- Code cleanups for irdm and erdma
- EFA reporting of 128 byte PCIe TLP support
- mlx5 more agressively uses the out of order HW feature
- Big rework of how state machines and tasks work in rxe
- Fix a syzkaller found crash netdev refcount leak in siw
- bnxt_re revises their HW description header
- Congestion control for bnxt_re
- Use mmu_notifiers more safely in hfi1
- mlx5 gets better support for PCIe relaxed ordering inside VMs"

After necessary configuration, driver should wait hardware finishing
initialization. The wait sets at CMDQ related function though it has
nothing to do with CMDQ. Refactor this part to make code cleaner.

ERDMA device may be probed before its associated netdevice, returning
-EPROBE_DEFER allows OS try to probe erdma device later.

ERDMA driver use a workqueue for asynchronous reflush command posting.
Implement the lifecycle of this workqueue.

Introduce "capacity flags" field at where hardware put all zeros originally
in "query device" response. Using this field, hardware can report atomic
feature if supports.

Hardware now support jumbo frame for RDMA. So we introduce a new CMDQ
message to support mtu change notification.

Many of erdma's includes are redundant, because they are already included
indirectly by kernel headers or custom headers. So we remove all the
unnecessary direct-includes. Besides, add linux/pci.h to erdma.h because
it's also used in the file.

Add the main erdma module, which provides interface to infiniband
subsystem.
This commit includes a modification from Christophe, that using the bitmap
API to allocate bitmaps instead of hand-writing. And the commit also fixes
warnings reported by static checkers.
