Fork of alistair23 Linux kernel for reMarkable from https://github.com/alistair23/linux

A scalable mode DMAR table walk would involve looking at bits in each stage of walk, like, 1. Is PASID enabled in the context entry? 2. What's the size of PASID directory? 3. Is the PASID directory entry present? 4. Is the PASID table entry present? 5. Number of PASID table entries? Hence, add these macros that will later be used during this walk. Apart from adding new macros, move existing macros (like pasid_pde_is_present(), get_pasid_table_from_pde() and pasid_supported()) to appropriate header files so that they could be reused.

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 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.
