Suganath Prabu S d6adc251dd scsi: mpt3sas: Force PCIe scatterlist allocations to be within same 4 GB region
According to the MPI specification, PCIe SGL buffers can not cross a 4 GB
boundary.

While allocating, if any buffer crosses the 4 GB boundary, then:

 - Release the already allocated memory pools; and

 - Reallocate them by changing the DMA coherent mask to 32-bit

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.
