As HAVE_ARCH_HUGE_VMAP and HAVE_ARCH_HUGE_VMALLOC is supported, we can implement arch_vmap_pte_range_map_size and arch_vmap_pte_supported_shift for Svnapot to support huge vmap about napot size. It can be tested by huge vmap used in pci driver. Huge vmalloc with svnapot can be tested by test_vmalloc with [1] applied, and probe this module to run fix_size_alloc_test with use_huge true.

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.
