map_groups__fixup_end() was called to set the end addresses of kernel and module maps. But now since machine__create_modules() sets the end address of modules properly, the only remaining piece is the kernel map. We can set it with adjacent module's address directly instead of calling map_groups__fixup_end(). If there's no module after the kernel map, the end address will be ~0ULL. Since it also changes the start address of the kernel map, it needs to re-insert the map to the kmaps in order to keep a correct ordering. Kim reported that it caused problems on ARM64.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
