Add mmap and SYSCALL test cases. SYSCALL test cases: - LAM supports set metadata in high bits 62:57 (LAM_U57) of a user pointer, pass the pointer to SYSCALL, SYSCALL can dereference the pointer and return correct result. - Disable LAM, pass a pointer with metadata in high bits to SYSCALL, SYSCALL returns -1 (EFAULT). MMAP test cases: - Enable LAM_U57, MMAP with low address (below bits 47), set metadata in high bits of the address, dereference the address should be allowed. - Enable LAM_U57, MMAP with high address (above bits 47), set metadata in high bits of the address, dereference the address should be allowed.

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.
