Add PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP support on arm64. We don't need any special handling for PTRACE_SYSEMU_SINGLESTEP. It's quite difficult to generalize handling PTRACE_SYSEMU cross architectures and avoid calls to tracehook_report_syscall_entry twice. Different architecture have different mechanism to indicate NO_SYSCALL and trying to generalise adds more code for no gain.

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.
