Hi,
This patch set converts mlx5 driver to use auxiliary bus [1].
In this series, we are connecting three subsystems (VDPA, netdev and
RDMA) through mlx5_core PCI driver. That driver is responsible to create
proper devices based on supported firmware.

This flow has become crufty and confusing. Revise it so that the rules
on how UMR is used with MRs is much clearer and more correct.
Fixes a few minor bugs in ODP and rereg_mr where disallowed things were
not properly blocked.

Hi,
This series mainly changes mlx4, mlx5, and mthca drivers to future
change of QP allocation scheme.
The rdmavt driver will be sent separately.

GCOV built with GCC 10 doesn't initialize n_function variable.
This produces different kernel panics as was seen by Colin in
Ubuntu [1] and me in FC 32 [2].
As a workaround, let's disable GCOV build for broken GCC 10 version.

This series adds a new constructor for a scatter gather table. Like
sg_alloc_table_from_pages function, this function merges all contiguous
chunks of the pages a into single scatter gather entry.
In contrast to sg_alloc_table_from_pages, the new API all
with the Infiniband driver that allocates a single page for hold the
pages. For 1TB memory registration, the temporary buffer would consume only
4KB, instead of 2GB.
