KVM overloads #PF to indicate two types of not-actually-page-fault events. Right now, the KVM guest code intercepts them by modifying the IDT and hooking the #PF vector. This makes the already fragile fault code even harder to understand, and it also pollutes call traces with async_page_fault and do_async_page_fault for normal page faults. Clean it up by moving the logic into do_page_fault() using a static branch. This gets rid of the platform trap_init override mechanism completely.

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.
