From 61b1a94254a2158d053458764a5bd30331d73a54 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 20 Sep 2005 13:52:50 +1000 Subject: [PATCH] ppc64: Store virtual address in TLB flush batches This patch slightly change the TLB flush batch mecanism so that we store the full vaddr (including vsid) when adding an entry to the batch so that the flush part doesn't have to get to the context. This cleans it a bit, and paves the way to future updates like dynamic vsids.
