The header flag XLF_CAN_BE_LOADED_ABOVE_4G will inform us whether allocations above 4 GiB for kernel, command line, etc are permitted, so we take it into account when calling efi_allocate_pages() etc. However, CONFIG_EFI_STUB implies CONFIG_RELOCATABLE, and so the flag is guaranteed to be set on x86_64 builds, whereas i386 builds are guaranteed to run under firmware that will not allocate above 4 GB in the first place. So drop the check, and just pass ULONG_MAX as the upper bound for all allocations.

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.
