  "message": "arm64: realm: Fix PTE_NS_SHARED for 52bit PA support\n\nWith LPA/LPA2, the top bits of the PFN (Bits[51:48]) end up in the lower bits\nof the PTE. So, simply creating a mask of the \"top IPA bit\" doesn\u0027t work well\nfor these configurations to set the \"top\" bit at the output of Stage1\ntranslation.\n\nFix this by using the __phys_to_pte_val() to do the right thing for all\nconfigurations.\n\nTested using, kvmtool, placing the memory at a higher address (-m \u003csize\u003e@\u003cAddr\u003e).\n\n e.g:\n # lkvm run --realm -c 4 -m 512M@@128T -k Image --console serial\n\n sh-5.0# dmesg | grep \"LPA2\\|RSI\"\n[    0.000000] RME: Using RSI version 1.0\n[    0.000000] CPU features: detected: 52-bit Virtual Addressing (LPA2)\n[    0.777354] CPU features: detected: 52-bit Virtual Addressing for KVM (LPA2)\n\nFixes: 399306954996 (\"arm64: realm: Query IPA size from the RMM\")\nCc: Catalin Marinas \u003ccatalin.marinas@arm.com\u003e\nCc: Steven Price \u003csteven.price@arm.com\u003e\nCc: Will Deacon \u003cwill@kernel.org\u003e\nSigned-off-by: Suzuki K Poulose \u003csuzuki.poulose@arm.com\u003e\nReviewed-by: Steven Price \u003csteven.price@arm.com\u003e\nReviewed-by: Catalin Marinas \u003ccatalin.marinas@arm.com\u003e\nSigned-off-by: Will Deacon \u003cwill@kernel.org\u003e\n",
