From f1157141636848f52c5f74040bed0ba355cf59b7 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Tue, 7 Dec 2010 00:55:29 -0800 Subject: x86, apic: Remove early_init_lapic_mapping() It is almost the same as smp_register_lapic_addr(). We just need to let smp_read_mpc() call smp_register_lapic_addr() when early==1. Add the apic_printk to smp_register_lapic_address() Signed-off-by: Yinghai Lu Cc: Suresh Siddha Cc: "Eric W.
