Catalin Marinas 761b9b366c elf: Introduce the ARM MTE ELF segment type
Memory tags will be dumped in the core file as segments with their own
type. Discussions with the binutils and the generic ABI community
settled on using new definitions in the PT_*PROC space (and to be
documented in the processor-specific ABIs).

Introduce PT_ARM_MEMTAG_MTE as (PT_LOPROC + 0x1). Not included in this
patch since there is no upstream support but the CHERI/BSD community
will also reserve:

  #define PT_ARM_MEMTAG_CHERI    (PT_LOPROC + 0x2)
  #define PT_RISCV_MEMTAG_CHERI  (PT_LOPROC + 0x3)

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.
