We get the following compilation error if CONFIG_SPARSEMEM_VMEMMAP is set.
---------------------------------------------------------------
./arch/riscv/include/asm/pgtable-64.h: In function ‘pud_page’:
./include/asm-generic/memory_model.h:54:29: error: ‘vmemmap’ undeclared
(first use in this function); did you mean ‘mem_map’?
#define __pfn_to_page(pfn) (vmemmap + (pfn))
^~~~~~~
./include/asm-generic/memory_model.h:82:21: note: in expansion of
macro ‘__pfn_to_page’
#define pfn_to_page __pfn_to_page
^~~~~~~~~~~~~
./arch/riscv/include/asm/pgtable-64.h:70:9: note: in expansion of macro
‘pfn_to_page’
return pfn_to_page(pud_val(pud) >> _PAGE_PFN_SHIFT);
---------------------------------------------------------------
Fix the compliation errors by moving all the address space definition
macros before including pgtable-64.h.

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.
