From 7bc9036d160c6235d96e1bed49331696d7fa9a09 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Fri, 10 May 2019 11:58:37 +0530 Subject: arch/cpu: Rename mp_get_apic_id() and add_cpu_map_entry() function This patch renames mp_get_apic_id() to cpu_get_apic_id() and add_cpu_map_entry() to cpu_add_map_entry() in order access it outside CONFIG_PARALLEL_MP kconfig scope. Also make below changes - Make cpu_add_map_entry() function available externally to call it from mp_init.c and lapic_cpu_init.c.
