Update the directMap page counters for Hash. Hash by default always uses mmu_linear_psize only, for it's directMap. However, once the kernel has booted and the dmesg log is wrapped over there is no way of knowing the kernel linear pagesize with Hash mmu. Features like debug_page_alloc can make mmu_linear_psize to be PAGE_SIZE instead of PMD / PUD mappings. It would be easier if we have this info printed in proc meminfo similar to Radix for debugging purposes.

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.
