+ * Address space layout.
+ *
+ * ARMv8 implements up to a 48 bit virtual address space. The address space is
+ * split into 2 regions at each end of the 64 bit address space, with an
+ * out of range "hole" in the middle.
+ *
+ * We limit the size of the two spaces to 39 bits each.
+ *
+ * Upper region: 0xffffffffffffffff
+ * 0xffffff8000000000
+ *
+ * Hole: 0xffffff7fffffffff
+ * 0x0000008000000000
+ *
+ * Lower region: 0x0000007fffffffff
+ * 0x0000000000000000
+ *
+ * We use the upper region for the kernel, and the lower region for userland.
+ *
+ * We define some interesting address constants:
+ *
+ * VM_MIN_ADDRESS and VM_MAX_ADDRESS define the start and end of the entire
+ * 64 bit address space, mostly just for convenience.
+ *
+ * VM_MIN_KERNEL_ADDRESS and VM_MAX_KERNEL_ADDRESS define the start and end of
+ * mappable kernel virtual address space. VM_MIN_KERNEL_ADDRESS is basically
+ * arbitrary, a convenient address is chosen which allows both the kernel text
+ * and data and the prom's address space to be mapped with 1 4mb tsb page.
+ * VM_MAX_KERNEL_ADDRESS is variable, computed at startup time based on the
+ * amount of physical memory available. Each 4mb tsb page provides 1g of
+ * virtual address space, with the only practical limit being available
+ * phsyical memory.
+ *
+ * VM_MIN_USER_ADDRESS and VM_MAX_USER_ADDRESS define the start and end of the
+ * user address space. There are some hardware errata about using addresses
+ * at the boundary of the va hole, so we allow just under 43 bits of user
+ * address space. Note that the kernel and user address spaces overlap, but
+ * this doesn't matter because they use different tlb contexts, and because
+ * the kernel address space is not mapped into each process' address space.
