  "message": "mmu: support only identity RAM mapping\n\nWe no longer plan to support a split address space with\nthe kernel in high memory and per-process address spaces.\nBecause of this, we can simplify some things. System RAM\nis now always identity mapped at boot.\n\nWe no longer require any virtual-to-physical translation\nfor page tables, and can remove the dual-mapping logic\nfrom the page table generation script since we won\u0027t need\nto transition the instruction point off of physical\naddresses.\n\nCONFIG_KERNEL_VM_BASE and CONFIG_KERNEL_VM_LIMIT\nhave been removed. The kernel\u0027s address space always\nstarts at CONFIG_SRAM_BASE_ADDRESS, of a fixed size\nspecified by CONFIG_KERNEL_VM_SIZE.\n\nDriver MMIOs and other uses of k_mem_map() are still\nvirtually mapped, and the later introduction of demand\npaging will result in only a subset of system RAM being\na fixed identity mapping instead of all of it.\n\nSigned-off-by: Andrew Boie \u003candrew.p.boie@intel.com\u003e\n",
