Similar to the recently fixed stage-2 walker, the hyp map walker increments the PA and VA of a walk separately. Unlike stage-2, there is no bug here as the map walker has exclusive access to the stage-1 page tables. Nonetheless, in the interest of continuity throughout the page table code, tweak the hyp map walker to avoid incrementing the PA and instead use the VA as the authoritative source of how far along a table walk has gotten. Calculate the PA to use for a leaf PTE by adding the offset of the VA from the start of the walk to the starting PA.

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.
