I'm having trouble building the latest rsync of the benh kernel. First I got an undefined symbol "xmon_printf" trying to link kernel.o, so I ran menuconfig and added xmon into the kernel. Now I fail trying to build misc.o with
/usr/src/linux-2.4/include/asm/cputable.h:45: `NR_CPUS' undeclared here (not in a function) and I'm not sure what to try next
