Right now the code uses a global struct to store vendor-ids and another global variable to store the vendor-patch-function. There exist specific cases where we'll need to patch the kernel at an even earlier stage, where trying to write to a static variable might actually result in hangs. Also collecting the vendor-information consists of 3 sbi-ecalls (or csr-reads) which is pretty negligible in the context of booting a kernel. So rework the code to not rely on static variables and instead collect the vendor-information when a round of alternatives is to be applied.

README
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.
