[PATCH 3/4] x86: add kprobe-booster to X86_64

[Harvey Harrison]

Sorry I missed an ifdef in this patch in the following hunk:

@@ -183,6 +185,9 @@ retry:
        }
 
        switch (opcode & 0xf0) {
+#ifdef X86_64

        case 0x60:
                if (0x63 < opcode && opcode < 0x67)
                        goto retry; /* prefixes */

Just add the #ifdef to only catch case 0x40.
