On RISC-V platforms with hardware VMID support, we share same VMID for all VCPUs of a particular Guest/VM. This means we might have stale G-stage TLB entries on the current Host CPU due to some other VCPU of the same Guest which ran previously on the current Host CPU. To cleanup stale TLB entries, we simply flush all G-stage TLB entries by VMID whenever underlying Host CPU changes for a VCPU.

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.
