Subject: [PATCH 3/4] x86: add kprobe-booster to X86_64
Date: Mon, 17 Dec 2007 14:27:44 -0800 [thread overview]
Message-ID: <1197930464.23402.112.camel@brick> (raw)
Sorry I missed an ifdef in this patch in the following hunk:
@@ -183,6 +185,9 @@ retry:

switch (opcode & 0xf0) {
+#ifdef X86_64
+ case 0x40:
+ goto retry; /* REX prefix is boostable */
case 0x60:
if (0x63 < opcode && opcode < 0x67)
goto retry; /* prefixes */
Just add the #ifdef to only catch case 0x40.
