Currently, the .alt.smp.init section contains the virtual addresses of the patch sites. Since patching may occur both before and after switching into virtual mode, this requires some manual handling of the address when applying the UP alternative. Let's simplify this by using relative offsets in the table entries: this allows us to simply add each entry's address to its contents, regardless of whether we are running in virtual mode or not.

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.
