Now that kasan shadow region is next to the kernel, for sv48, this region won't be aligned on PGDIR_SIZE and then when populating this region, we'll need to get down to lower levels of the page table. So instead of reimplementing the page table walk for the early population, take advantage of the existing functions used for the final population. Note that kasan swapper initialization must also be split since memblock is not initialized at this point and as the last PGD is shared with the kernel, we'd need to allocate a PUD so postpone the kasan final population after the kernel population is done.

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.
