+
+The purpose of this patch:
+
+- Adopt the DMA API (jazzsonic, macsonic & core driver).
+
+- Adopt the driver model (macsonic).
+
+This part was cribbed from jazzsonic. As a consequence, macsonic once 
+again works as a module. Driver model is also used by the DMA calls.
+
+- Support 16 bit cards (macsonic & core driver, also affects jazzsonic)
+
+This code was adapted from the mac68k linux 2.2 kernel, where it has 
+languished for a long time.
+
+- Support more 32-bit mac cards (macsonic)
+
+Also from mac68k repo.
+
+- Zero-copy buffer handling (core driver)
+
+Provides a nice performance improvement. The new algorithm incidentally 
+helped to replace the old Jazz DMA code.
+
+The patch was tested on a variety of macs (several 32-bit quadra built-in 
+NICs, a 16-bit LC PDS NIC and a 16-bit comm-slot NIC), and also on MIPS 
+Jazz.
+
+This patch combines the three previous patches in this thread.
