- * address map:
- *
- * FreeBSD:
- * 0x00000000->0x0E000000 224M C program and memory allocation.
- * 0x0E000000->0x10000000 32M Foreign segment.
- * 0x10000000->0x20000000 256M Read-Only Space.
- * 0x20000000->0x30000000 256M Reserved for shared libraries.
- * 0x30000000->0x38000000 128M Static Space.
- * 0x38000000->0x40000000 128M Binding stack growing up.
- * 0x40000000->0x48000000 128M Control stack growing down.
- * 0x48000000->0xC8000000 2GB Dynamic Space.
- * 0xE0000000-> 256M C stack - Alien stack.
- *
- * OpenBSD:
- * almost the same as FreeBSD
- *
- * Linux: Note that this map has some problems and requires some further
- * development so is not implemented below.
- * 0x00000000->0x08000000 128M Unused.
- * 0x08000000->0x10000000 128M C program and memory allocation.
- * 0x10000000->0x20000000 256M Read-Only Space.
- * 0x20000000->0x28000000 128M Binding stack growing up.
- * 0x28000000->0x38000000 256M Static Space.
- * 0x38000000->0x40000000 128M Control stack growing down.
- * 0x40000000->0x48000000 128M Reserved for shared libraries.
- * 0x48000000->0xB8000000 1.75G Dynamic Space.
- *
- * FIXME: There's something wrong with addressing maps which are so
- * brittle that they can be commented as fixed addresses. Try to
- * parameterize these so they can be set at build time.
