[1/3] arm64: Add missing include of asm/cpufeature.h to asm/mmu.h commit: 7e04f05984dd03edad7daaa4fa97958b7133c62a [2/3] KVM: arm64: Generate hyp_constants.h for the host commit: ed4ed15d571065eb66ea718d7f6050553586417d [3/3] KVM: arm64: Move host EL1 code out of hyp/ directory commit: 9429f4b0412d05243237c7695c59d0a7b1174492 Cheers, M.
Hi folks, This series tidies up the header file usage for the nvhe hyp object so that header files under arch/arm64/kvm/hyp/include are not included by host code running at EL1. For definitions that are shared between the host and hypervisor, these are either moved to headers under arch/arm64/include/asm/ or are generated by kbuild along similar lines to asm-offsets.h. For now, this allows us to tidy up some of the pKVM reserved memory handling, but in future this will also allow the pKVM EL2 data structures to avoid polluting the host namespace.
