In JUMP_VIRT_ADDR we are performing an or calculation on address value directly from pcaddi. This will only work if we are currently running from direct 1:1 mapping addresses or firmware's DMW is configured exactly same as kernel. Still, we should not rely on such assumption. Fix by overriding higher bits in address comes from pcaddi, so we can get rid of or operator.

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.
