Jeff Xu 072cd213b7 selftest mm/mseal: fix test_seal_mremap_move_dontunmap_anyaddr 
the syscall remap accepts following:

mremap(src, size, size, MREMAP_MAYMOVE | MREMAP_DONTUNMAP, dst)

when the src is sealed, the call will fail with error code:
EPERM

Previously, the test uses hard-coded 0xdeaddead as dst, and it
will fail on the system with newer glibc installed.

This patch removes test's dependency on glibc for mremap(), also
fix the test and remove the hardcoded address.

README 

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 reStructuredText 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.
