From 098e8957afd86323db04cbb8deea3bd158f9cc71 Mon Sep 17 00:00:00 2001 From: Jeremy Kerr Date: Wed, 11 Mar 2009 17:55:52 +0000 Subject: [PATCH] powerpc: Add dispatch trace log fields to lppaca PAPR v2.3 defines fields in the virtual processor area for a dispatch trace log (DLT). Since we'd like to use the DLT, add the necessary fields to struct lppaca.
