The RISC-V ISA only supports flushing the instruction cache for the local CPU core. Currently we always offload the remote TLB flushing to the SBI, which then issues an IPI under the hoods. But with M-mode we do not have an SBI so we have to do it ourselves. IPI to the other nodes using the existing kernel helpers instead if we have native clint support and thus can IPI directly from the kernel.

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.
