  * In an LP64 environment, the traditional Mach VM interface names are
  * really just a second instance of the "wide" Mach VM interfaces.
  *
+ * For ARM, which doesn't support two address space sizes, use the "wide"
+ * interfaces as well, to reduce the amount of duplicate code compiled
+ * into the kernel.
+ *
  * The _MACH_VM_PUBLISH_AS_LOCAL_ flag triggers mach_vm.defs to export
  * the local names instead.
+ *
+ * LIBSYSCALL_INTERFACE indicates that we are building the
+ * machine-independent headers for Libsyscall
