From 4ec60c76d5ab513e375f17b043d2b9cb849adf6c Mon Sep 17 00:00:00 2001 From: Igor Mammedov Date: Wed, 6 Jul 2016 08:20:40 +0200 Subject: pc: cpu: Consolidate apic-id validity checks in pc_cpu_pre_plug() Machine code knows about all possible APIC IDs so use that instead of hack which does O(n^2) complexity duplicate checks, interating over global CPUs list. As result duplicate check is done only once with O(log n) complexity.
