Add hstate for each supported hugepage size using arch initcall. * no hugepage parameters Without hugepage parameters, only a default hugepage size is available for dynamic allocation. It's different, for example, from x86_64 and sparc64 where all supported hugepage sizes are available. * only default_hugepagesz= is specified and set not to HPAGE_SIZE In spite of the fact that default_hugepagesz= is set to a valid hugepage size, it's treated as unsupported and reverted to HPAGE_SIZE. Such behaviour is also different from x86_64 and sparc64.

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.
