Why is there i386 MMU-specific stuff in the NetBSD VM >code? (In vm_glue.c for example :-)). Please refer to >the ifdefs... Granted, NetBSD has a few i386 and pc532 #ifdef's in the MI vm code. However, those are XXX'd, and will eventually go away. However, the notion of having to write an i386 MMU emulator for the PowerPC seems ... wrong. I was simply reacting to Terry's comment that he wanted to do so so he could more easily track FreeBSD's VM changes. Why that would be necessary only leads me to believe that there are more assumptions than necessary. -- Jason R. Thorpe <thorpej@bayarea.net>
