If we have specialized interrupt controller (such as AIA IMSIC) which allows supervisor mode to directly inject IPIs without any assistance from M-mode or HS-mode then using such specialized interrupt controller, we can do remote TLB flushes directly from supervisor mode instead of using the SBI RFENCE calls. This patch extends remote TLB flush functions to use supervisor mode IPIs whenever direct supervisor mode IPIs.are supported by interrupt controller.

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.
