Then you have physical page tracking structures in the kernel, which take several more gigabytes. There is also the kernel page table, but that's generally mapped using 1G pages, so it doesn't take much memory at all (circa 8kb to map a 40-bit address space). Intel CPU's support a 44-bit physical address space, AMD and ARM64 support a 48-bit physical address space all of which needs to be part of the kernel identity mapping.
