+Subject: Fix speedstep-smi assembly bug in speedstep_smi_ownership
+Message-Id: <20060324194037.3a7495b7.akpm@osdl.org>
+
+From: Andrew Morton <akpm@osdl.org>
+
+Fix bug identified by Linus Torvalds <torvalds@osdl.org>: the `out'
+instruction depends upon the state of memory_data[], so we need to tell gcc
+that before executing it. (The opcode, not gcc).
+
+Fixes http://bugzilla.kernel.org/show_bug.cgi?id=5553
+
+Thanks to Antonio Ospite <ospite@studenti.unina.it> for testing.
