In some case initrd can be large. For example, it could be a netboot image loaded by u-root, that is kexec'ing into it. The maximum size of initrd is arbitrary set to 2G. Also, the limit is not very obvious because it is hidden behind a generic INT_MAX macro. Theoretically, we could make it LONG_MAX, but it is safer to keep it sane, and just increase it to 4G. Increase the size to 4G, and make it obvious by having a new macro that specifies the maximum file size supported by kexec_file_load() syscall: KEXEC_FILE_SIZE_MAX.

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.
