Following up on some off-list email, I've discovered that files.amd64, where I added the defparam line, is inside "ifdef xen"..."endif". This seems to reinforce what you just said. HOWEVER....so is the defparam line for opt_realmem.h, another of the .h files included in that block of unconditional #include lines in amd64/machdep.c. And, spot-checking a third include file, there's opt_cpureset_delay.h among the #includes, and the only files in all of /usr/src that include the string "cpureset_delay" are sys/arch/amd64/amd64/machdep.c and sys/arch/i386/i386/machdep.c, so I have no idea what makes config generate opt_cpureset_delay.h. I clearly need to dig deeper. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
