At the time being, initial MMU setup allows 24 Mbytes of DATA and 8 Mbytes of code. Some debug setup like CONFIG_KASAN generate huge kernels with text size over the 8M limit and data over the 24 Mbytes limit. Here is an 8xx kernel compiled with CONFIG_KASAN_INLINE for one of my boards: [root@po16846vm linux-powerpc]# size -x vmlinux text data bss dec hex filename 0x111019c 0x41b0d4 0x490de0 26984528 19bc050 vmlinux This patch maps up to 32 Mbytes code based on _einittext symbol and allows 32 Mbytes of memory instead of 24.

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.
