From 0359b0e2d0bbd28289c38ebe779b5f1c61f8ccc8 Mon Sep 17 00:00:00 2001 From: Javi Merino Date: Wed, 29 Aug 2012 18:32:18 +0100 Subject: [PATCH] arm64: head: match all affinity levels in the pen of the secondaries The reg property of the cpu nodes in the DT now contains all the affinity levels in (MPIDR[39:32] and MPIDR[23:0]) and that's what boot_secondary() writes in the pen, so increase the mask in secondary_holding_pen accordingly.
