RISC-V systems perform TLB shootdows via the SBI, which currently performs an IPI to each of the remote harts which then performs a local TLB flush. This process is a bit on the slow side, but we can at least speed it up for some common cases by restricting the set of harts to shoot down to the actual set of harts that are currently participating in the given mm context, as opposed to the entire system. This should provide a measurable performance increase, but we haven't measured it. Regardless, it seems like obviously the right thing to do here.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
