There are lots of code changes here for a single patch but as you have mentioned shared KVM bits would have prevented splitting arm and arm64 changes into separate patches. Just curious, are you planning to respin this patch sooner after fixing the reported build problems caused by missing p4d_offset_kimg() and p4d_sect() definitions ? - Anshuman _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
