Provide IDTENTRY variants for system vectors to consolidate the different mechanisms to emit the ASM stubs for 32- and 64-bit. On 64-bit this also moves the stack switching from ASM to C code. 32-bit will excute the system vectors w/o stack switching as before. The simple variant is meant for "empty" system vectors like scheduler IPI and KVM posted interrupt vectors. These do not need the full glory of irq enter/exit handling with softirq processing and more.

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.
