This series contains fixes for some issues observed since the KVM arm64 pull request for 4.17.
*ahem*, that should read 4.18.
The first patch (from Mark Rutland) adds a straightforward helper to modify particular bits in a system register conditionally. This is used by patch 3 (though obviously it could be coded round and patch 1 dropped, if preferred). See other patches for details of the individual fixes.
