Sorry this line:
 >>>>>>>>>>>>>
$ cp /usr/src/sys/<arch>/include/param.h /tmp/param.h && perl -ple 
's/#define PREEMPTIVE.+\n$//i' /tmp/param.h > 
/usr/src/sys/<arch>/include/param.h /tmp/param.h
 >>>>>>>>>>>>>

Should read:
 >>>>>>>>>>>>>
$ cp /usr/src/sys/<arch>/include/param.h /tmp/param.h &&  perl -ple 
's/^#define[\t\s]+PREEMPTION//i' /tmp/param.h > 
/usr/src/sys/<arch>/include/param.h
