LLD will occasionally error out with a '__init_end does not converge' error if INIT_IDMAP_DIR_SIZE is defined in terms of _end, as this results in a circular dependency. Counter this by dimensioning the initial IDMAP page tables based on a new boundary marker 'kimage_limit', and define it such that its value should not change as a result of the initdata segment being pushed over a 64k segment boundary due to changes in INIT_IDMAP_DIR_SIZE, provided that its value doesn't change by more than 2M between linker passes.

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.
