Konstantin Taranov 293fcadf2f RDMA/mana_ib: Use virtual address in dma regions for MRs
[ Upstream commit 2d5c008157 ]

Introduce mana_ib_create_dma_region() to create dma regions with iova
for MRs. It allows creating MRs with any page offset. Previously,
only page-aligned addresses worked.

For dma regions that must have a zero dma offset (e.g., for queues),
mana_ib_create_zero_offset_dma_region() is added.
To get the zero offset, ib_umem_find_best_pgoff() is used with zero
pgoff_bitmask.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
