Edward Srouji 19c262401e RDMA/mlx5: Fix UMR modifying of mkey page size 
[ Upstream commit c4f96972c3 ]

When changing the page size on an mkey, the driver needs to set the
appropriate bits in the mkey mask to indicate which fields are being
modified.
The 6th bit of a page size in mlx5 driver is considered an extension,
and this bit has a dedicated capability and mask bits.

Previously, the driver was not setting this mask in the mkey mask when
performing page size changes, regardless of its hardware support,
potentially leading to an incorrect page size updates.

This fixes the issue by setting the relevant bit in the mkey mask when
performing page size changes on an mkey and the 6th bit of this field is
supported by the hardware.

Fixes: cef7dde883 ("net/mlx5: Expand mkey page size to support 6 bits")

README 

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 reStructuredText 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.
