A new VMID allocator for arm64 KVM use. This is based on arm64 ASID allocator algorithm. One major deviation from the ASID allocator is the way we flush the context. Unlike ASID allocator, we expect less frequent rollover in the case of VMIDs. Hence, instead of marking the CPU as flush_pending and issuing a local context invalidation on the next context switch, we broadcast TLB flush + I-cache invalidation over the inner shareable domain on rollover.

README
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.
