+         Qemu is a software emulator which among other architectures also
+         can simulate a MIPS32 4Kc system.  This patch adds support for the
+         system architecture that currently is being simulated by Qemu.  It
+         will eventually be removed again when Qemu has the capability to
+         simulate actual MIPS hardware platforms.  More information on Qemu
+         can be found at http://www.linux-mips.org/wiki/Qemu.
