With "riscv: mm: add THP support on 64-bit", mk_pmd() function introduce build errors, 1.build with CONFIG_ARCH_RV32I=y: arch/riscv/include/asm/pgtable.h: In function 'mk_pmd': arch/riscv/include/asm/pgtable.h:513:9: error: implicit declaration of function 'pfn_pmd'; did you mean 'pfn_pgd'? [-Werror=implicit-function-declaration] 2.build with CONFIG_SPARSEMEM=y && CONFIG_SPARSEMEM_VMEMMAP=n arch/riscv/include/asm/pgtable.h: In function 'mk_pmd': include/asm-generic/memory_model.h:64:14: error: implicit declaration of function 'page_to_section'; did you mean 'present_section'? [-Werror=implicit-function-declaration] Move the definition of mk_pmd to pgtable-64.h to fix the first error. Use macro definition instead of inline function for mk_pmd to fix the second problem. It is similar to the mk_pte macro.

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.
