From 1ece355b6825b7c61d1dc39a5c6cf49dc746e193 Mon Sep 17 00:00:00 2001 From: Milton Miller Date: Tue, 10 May 2011 19:29:42 +0000 Subject: powerpc: Add kconfig for muxed smp ipi support Compile the new smp ipi mux and demux code only if a platform will make use of it. The new config is selected as required. The new cause_ipi smp op is only available conditionally to point out configs where the select is required; this makes setting the op an immediate fail instead of a deferred unresolved symbol at link. This also creates a new config for power surge powermac upgrade support that can be disabled in expert mode but is default on. I also removed the depends / default y on CONFIG_XICS since it is selected by PSERIES.
