From 105765f451d3ff007bb4ae3761e825686d9615db Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Fri, 1 Apr 2011 09:23:37 +1100 Subject: powerpc/smp: Don't expose per-cpu "cpu_state" array Instead, keep it static, expose an accessor and use that from the PowerMac code. Avoids easy namespace collisions and will make it easier to consolidate with other implementations.
