The code in secondary_park is currently placed in the .init section. The kernel reclaims and clears this code when it finishes booting. That causes the cores parked in it to go to somewhere unpredictable, so we move this function out of init to make sure the cores stay looping there. The instruction bgeu a0, t0, .Lsecondary_park may have "a relocation truncated to fit" issue during linking time. It is because that sections are too far to jump. Let's use tail to jump to the .Lsecondary_park.

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.
