Shutemov" Precedence: bulk List-ID: X-Mailing-List: linux-mips@vger.kernel.org Use KVM_SET_USER_MEMORY_REGION2 throughout KVM's selftests library so that support for guest private memory can be added without needing an entirely separate set of helpers. Note, this obviously makes selftests backwards-incompatible with older KVM versions from this point forward.
