From c5f66596313734cd7e95cc748d643d3b9ba2ca81 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 17 Sep 2013 13:58:12 +0200 Subject: [PATCH] MIPS: Provide nice way to access boot CPU's data. boot_cpu_data is used the same as current_cpu_data but returns the CPU data for CPU 0. This means it doesn't have to use smp_processor_id() thus no need to disable preemption.
