+Subject: powerpc: Initialise paca->kstack before early_setup_secondary
+
+From: Matt Evans <matt@ozlabs.org>
+
+commit f761622e59433130bc33ad086ce219feee9eb961 upstream.
+
+As early setup calls down to slb_initialize(), we must have kstack
+initialised before checking "should we add a bolted SLB entry for our kstack?"
+
+Failing to do so means stack access requires an SLB miss exception to refill
+an entry dynamically, if the stack isn't accessible via SLB(0) (kernel text
+& static data).  It's not always allowable to take such a miss, and
+intermittent crashes will result.
+
+Primary CPUs don't have this issue; an SLB entry is not bolted for their
+stack anyway (as that lives within SLB(0)).  This patch therefore only
+affects the init of secondaries.
