Add hash_supports_debug_pagealloc() helper to detect whether debug_pagealloc can be supported on hash or not. This checks for both, whether debug_pagealloc config is enabled and the linear map should fit within rma_size/4 region size. This can then be used early during htab_init_page_sizes() to decide linear map pagesize if hash supports either debug_pagealloc or kfence.

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 reStructuredText 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.
