From cf8a056a2226754087320541fb4de743cc81cd2e Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Tue, 10 Apr 2012 16:20:54 +0000 Subject: [PATCH] powerpc: Clean up lppaca->cede_latency_hint We have a union containing fields from the old iseries hypervisor that has been reused for the cede latency hint. Since we no longer support iseries, remove the union completely.
