  "message": "KVM: arm64: Add PKVM_HYP_REQ_SPLIT\n\nWith the upcoming support for stage-2 huge mappings for protected VMs,\nwe need a way to split blocks. Since the host has its own \"copy\" of the\nguest stage-2 in the pkvm_mappings rb-tree, the split must be done\nsimultaneously for both that tree and the guest stage-2. Therefore the\nhypervisor can\u0027t do it on its own and must rely on the host for this\noperation.\n\nCreate a pKVM hypervisor request to ask the host to split a specified\nregion of the guest. On this request, the host can synchronise the split\nof both guest stage-2 (HVC __pkvm_host_split_guest) and the\npkvm_mappings tree. It ensures a concurrent VM teardown can\u0027t observe a\nPMD_SIZE pkvm_mapping while the guest stage-2 is PAGE_SIZE.\n\nSigned-off-by: Vincent Donnefort \u003cvdonnefort@google.com\u003e\n",
