x86 and um use 31 and 32 for PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP while powerpc uses different value maybe for legacy reasons. Though handling of PTRACE_SYSEMU can be made architecture independent, it's hard to make these definations generic. To add to this existing mess few architectures like arm, c6x and sh use 31 for PTRACE_GETFDPIC (get the ELF fdpic loadmap address). It's not possible to move the definations to generic headers. So we unfortunately have to duplicate the same defination to ARM64 if we need to support PTRACE_SYSEMU and PTRACE_SYSEMU_SINGLESTEP.

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.
