When neither LANTIQ nor MIPS_MALTA is set, 'physical_memsize' is not declared. This causes the build to fail with: mips-linux-ld: arch/mips/kernel/vpe-mt.o: in function `vpe_run': arch/mips/kernel/vpe-mt.c:(.text.vpe_run+0x280): undefined reference to `physical_memsize' LANTIQ is not using 'physical_memsize' and MIPS_MALTA's use of it is self-contained in mti-malta/malta-dtshim.c. Use of physical_memsize in vpe-mt.c appears to be unused, so eliminate this loader mode completely and require VPE programs to be compiled with DFLT_STACK_SIZE and DFLT_HEAP_SIZE defined.

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.
