pub const KERNEL_TEXT_START: usize = _; // 18_446_743_523_953_737_728usize

The kernel text region is where we load kernel modules. It starts at the 511th P4 entry and goes up until the KERNEL_OFFSET, which is where the nano_core itself starts. Actual value on x86_64: 0o177777_777_000_000_000_0000, or 0xFFFF_FF80_0000_0000
