SRQ uses a quantized and scaled page_offset, which is another variation of ib_umem_find_best_pgsz(). Add mlx5_umem_find_best_quantized_pgoff() to perform this calculation for each mailbox. A macro shows how the calculation is directly connected to the mailbox format. This new routine replaces the limited mlx5_ib_cont_pages() and mlx5_ib_get_buf_offset() pairing which would reject valid configurations rather than adjust the page_size to make it work. In turn this is much more aggressive about choosing large page sizes for these objects and when THP is enabled it will now often find a single page solution.

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.
