1. User addresses not accessed by the kernel but used for address space
management (e.g. ``mprotect()``, ``madvise()``). The use of valid
tagged pointers in this context is allowed with the exception of
``brk()``, ``mmap()`` and the ``new_address`` argument to
``mremap()`` as these have the potential to alias with existing
user addresses.
tagged pointers in this context is allowed with these exceptions:
NOTE: This behaviour changed in v5.6 and so some earlier kernels may
incorrectly accept valid tagged pointers for the ``brk()``,
``mmap()`` and ``mremap()`` system calls.
- ``brk()``, ``mmap()`` and the ``new_address`` argument to

NOTE: This behaviour changed in v5.6 and so some earlier kernels may
incorrectly accept valid tagged pointers for the ``brk()``,
``mmap()`` and ``mremap()`` system calls.
- The ``range.start``, ``start`` and ``dst`` arguments to the
``UFFDIO_*`` ``ioctl()``s used on a file descriptor obtained from
``userfaultfd()``, as fault addresses subsequently obtained by reading
the file descriptor will be untagged, which may otherwise confuse
tag-unaware programs.
NOTE: This behaviour changed in v5.14 and so some earlier kernels may
incorrectly accept valid tagged pointers for this system call.
