[PATCH v2 0/4] KVM: arm64: FPSIMD/SVE fixes for 4.17

This series contains fixes for some issues observed since the KVM arm64
pull request for 4.17.

It supersedes the previous v1 [1].

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 and changes from
the previous posting.
