Merge tag 'kvm-arm-fixes-for-v4.15-3-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/kvmarm/kvmarm
KVM/ARM Fixes for v4.15, Round 3 (v2)
Three more fixes for v4.15 fixing incorrect huge page mappings on systems using
the contigious hint for hugetlbfs; supporting an alternative GICv4 init
sequence; and correctly implementing the ARM SMCC for HVC and SMC handling.
