In preparation for moving startup32_load_idt() out of head_64.S and turning it into an ordinary function using the ordinary 32-bit calling convention, pull the global variable reference to boot32_idt up into startup32_load_idt() so that startup32_set_idt_entry() does not need to discover its own runtime physical address, which will no longer be correlated with startup_32 once this code is moved into .text. While at it, give startup32_set_idt_entry() static linkage.

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.
