[ Upstream commitbda166930c] Commitcca079ef8achanged sparc32 to use memblocks instead of bootmem, but also made high memory available via memblock allocation which does not work together with e.g. phys_to_virt and can lead to kernel panic. This changes back to only low memory being allocatable in the early stages, now using memblock allocation.

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.
