From 176d2cda0dee9f4f78f604ad72d6a111e8e38f3b Mon Sep 17 00:00:00 2001 From: Like Xu Date: Wed, 12 Jun 2019 16:40:58 +0800 Subject: [PATCH] i386/cpu: Consolidate die-id validity in smp context The field die_id (default as 0) and has_die_id are introduced to X86CPU. Following the legacy smp check rules, the die_id validity is added to the same contexts as leagcy smp variables such as hmp_hotpluggable_cpus(), machine_set_cpu_numa_node(), cpu_slot_to_string() and pc_cpu_pre_plug().
