From 2c8656204742a5e2d373972b139d0cc26ae93ff0 Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Tue, 19 Feb 2019 16:57:19 +0100 Subject: MIPS: SGI-IP27: do boot CPU init later To make use of per_cpu variables in interrupt code per_cpu_init() must be done after setup_per_cpu_areas(). This is achieved by calling it in smp_prepare_boot_cpu() via a new smp_ops method.
