From 5f76cb1f6c42e7575256595f85b8b97d84ec669e Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 30 Jan 2008 13:30:50 +0100 Subject: [PATCH] x86: single_step 0xf0 This fixes the 64-bit single-step handling code's instruction decoder to grok the 0xf0 (lock) prefix, which the 32-bit code already does correctly.
