[please bear with my relative n00bness; i'm trying to cut my teeth on some driver hackery] The ne2k driver ed(4) is disabled in amd64's kernel because it doesn't even compile. I gather that its use of kvtop() is deprecated as well (from the busdma project page). The pointer size problems with this driver I can deal with - there are some local variables declared int which need to be c(?)addr_t instead. But I have no idea what to do with kvtop(). Some googling yields hits about it being taken out, and about people being confused and the handbook section on the PCI bus containing an outdated section. But nothing about what the function does (well, I can guess virtual-to-physical address translation for kernelspace) or what is supposed to replace it. Barring a cvs log on some driver that's already made the transition to not using kvtop(), is there any documentation available on the issue? Or a hint, at least?
