Well - I noticed on the Web site the "official" F00F fix for 2.2.5 had been supplied. I got it downloaded, and applied it to my 2.2.5-RELEASE kernel source tree... (with some questionable fuzz-factors and line offsets), only to find it didn't work. That is, the F00F_HACK wasn't enabled. For example, the patch to machdep.c has: #if defined(I586_CPU) && !define(NO_F00F_HACK) which one would suppose to be fine. But... the 2.2.5 release of machdep.c doesn't include "opt_cpu.h", thus, I586_CPU isn't defined... so the F00F workaround doesn't get compiled in... (perhaps somewhere after the 2.2.5-RELEASE cut, this include was added?) trap.c suffers from this problem as well. The following diff to machdep.c and trap.c fixes the patch... - Dave Rivers - *** machdep.c~ Sat Dec 6 17:07:23 1997 --- machdep.c Sat Dec 6 17:10:33 1997 *************** *** 45,50 **** --- 45,51 ---- #include "opt_machdep.h" #include "opt_perfmon.h" #include "opt_userconfig.h" + #include "opt_cpu.h" #include <sys/param.h> #include <sys/systm.h> *** trap.c~ Sat Dec 6 16:16:41 1997 --- trap.c Sat Dec 6 17:11:03 1997 *************** *** 44,49 **** --- 44,50 ---- #include "opt_ktrace.h" #include "opt_ddb.h" + #include "opt_cpu.h" #include <sys/param.h> #include <sys/systm.h>
