Linux kernel source tree

Advertise that KVM's MMU is synchronized with the primary MMU for all flavors of PPC KVM support, i.e. advertise that the MMU is synchronized when CONFIG_KVM_BOOK3S_HV_POSSIBLE=y but the VM is not using hypervisor mode (a.k.a. PR VMs). PR VMs, via kvm_unmap_gfn_range_pr(), do the right thing for mmu_notifier invalidation events, and more tellingly, KVM returns '1' for KVM_CAP_SYNC_MMU when CONFIG_KVM_BOOK3S_HV_POSSIBLE=n and CONFIG_KVM_BOOK3S_PR_POSSIBLE=y, i.e. KVM already advertises a synchronized MMU for PR VMs, just not when CONFIG_KVM_BOOK3S_HV_POSSIBLE=y.

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.
