The INT3 call emulation selftest is a bit fragile as it relies on the compiler not inserting any extra instructions before the int3_selftest_ip() definition. Also, the int3_selftest_ip() symbol overlaps with the int3_selftest symbol(), which can confuse objtool. Fix those issues by slightly reworking the functionality and moving int3_selftest_ip() to a separate asm function. While at it, improve the naming.

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.
